how to calibrate the canon 7d for accurate focus

[@daveknowshow]

99.999 percent of people who viewed this video and applied this method have had perfect results! the video itself shows documented proof that this method works and surprisingly still there are trolls who comment that it is all wrong. how can a video recording showing it actually works and have all these people who viewed it, try it and have 99.999% success rate and be wrong? I get emails everyday from people all around the world who had success with this method. I will never understand youtube trolls who insist on trying to undermine a good thing like youtube where folks help other folks. it's quite sad.

[@Avidcomp]

Personal comment. I know once in my life I would have felt aggravated by the slow delivery of your voice, but times change and I've grown to appreciate it today. When one is trying to learn something...what's the rush? I've learned to slow down and take it easy if I'm going to learn, and learning is what's important. So thank you friend, you explained that really well.

[@susangreenlee2460]

I recently purchased my second Canon 7D with only 8,400 shutter clicks. It was mailed to me from Japan, so I wanted to calibrate the lenses I have with it. Thank you so much for this excellent video! I am so anxious to try it out later today.

[@daveknowshow]

awesome so glad I could help!

[@adude394]

I'm a lot of years late to this dance, but as the happy owner of a new (used) 7D, I'm really looking forward to trying this out. Glad I found it!

[@daveknowshow]

you will be happy with the 7d I still love mine.

[@s1dew1nd3r4]

@@daveknowshow just bought one of these myself with a 70-200 2.8 usm lens and tried capturing some action shots of my dogs tonight, man not one shot in focus - weirdly iv used plenty of other cameras and had good success but for some reason struggling with this setup, AI servo mode - would you suggest altering the sensitivity on the tracking?

[@daveknowshow]

@@s1dew1nd3r4 you can try that, it may help

[@dzungpham9174]

All I have to say is "THANK YOU VERY MUCH". Your explanation is very understandable. My problem has been resolved, not 100% but satisfactorily.

[@bassplayer60]

This is the best video I have heard to microadjust the lens...and it works. Thank you Sir

[@daveknowshow]

thank you so much for the kind words! it has brought me a lot of joy to share with others the things I have learned on my journey through this life. again thanks for taking your time to watch and share my video!

[@rhykko77]

I just bought one of these wonderful old cameras in like new condition .......Thank you VERY much for your detailed and thorough tutorial on this issue !!

[@daveknowshow]

you will love this camera! its a great camera that will last you a long time. I still shoot with mine today. glad you enjoyed the video

[@kimayres]

I've been suspecting for some time my lenses were focusing in front of where I was expecting. Following the instructions on your video, I've found all of them to be out and have adjusted them by between +10 and +18. Many thanks for this - it's greatly appreciated :)

[@daveknowshow]

your very welcome and thanks for watching. be sure and subscribe as I maybe adding more controversial yet honest assessments on photography related subjects.

[@MightyLuc]

My Dad left me this 7d and I never thought to calibrate the lens. Thanks for the tip.

[@AAO-Falcon]

I was looking at 7D reviews and stuff and yet i randomly clicked on this lets call it hella good knowledge to have. im going to buy a 7D when i get the money and this will help me so much encase i encounter the problem and to also help me in the future to calibrate my camera and lenses

[@Teddykhil]

Hi Dave, I'm no shit hot photographer, still getting used to my new 7D after having my 500D which I've had for 3 years or so. I don't get much time to get out and do a lot of shots so I can learn how to use the 7D as it's the only way really to learn how best to know your camera and take better pictures. Seeing this KZbin vid I will say is quite effective and well worth the look at and save in my Favorites lists. Thanks for doing this tutorial and helping US the mere mortals out there a few little tricks and also, to save money that IF we had to get a shop to teach us or adjust our camera for accurate focus, will save us money in the long run. Thanks buddy, Keep up the great vids. Kev.

[@daveknowshow]

thank you

[@cbnyjwl]

I am so happy I took the time to watch this video. I was seeing some very soft areas in my macro shots that have now been resolved. Good job sir.

[@daveknowshow]

thanks for dropping by my channel I'm sure you will have great results with this method. appreciate the kind words. peace love and respect Dave in Virginia

[@johnsedeski8340]

Dave...an excellent demonstration for a "down-n-dirty" way to get the job done. One important note. Remember that depth of field falls 1/3 in front & 2/3 behind critical focus. Don't look to balance the falloff evenly in front and behind. This is a mathematical constant for all lenses, all f stops and all focal lengths.

[@daveknowshow]

1/3 and 2/3 is not always the case. you can check that by using the online depth of field calculator. near limits and far limits change with relation to subject to camera distance, aperture and so on. here is an example of a near 1/2 and 1/2. lens set at 55mm aperture of f-1.0 Subject distance 8 ft Depth of field Near limit 7.88 ft Far limit 8.12 ft Total 0.24 ft In front of subject 0.12 ft (49%) Behind subject 0.12 ft (51%) Hyperfocal distance 522.5 ft Circle of confusion 0.019 mm

[@foundation922]

I like it!... Love it when people keep it simple, some people will always miss the point and complain, guess it's in their makeup? Now the fun starts by exercising what I've learned. Thank you for sharing this video Dave, your the man...

[@dstechstuff1131]

Saved my bacon. I have a canon 7D mk1 and it's just gone soft focus after 9 years of usage. Great tutorial. Hope the 7D has been a good camera for you. It has for me.

[@daveknowshow]

absolutely! I still use my original 7d and after using this method with my glass its a beast of a camera! I have put it through a lot of rough use and some would say abuse. its still going strong! thanks for watching and appreciate the kind words and the time you took to leave a comment. much appreciated!

[@dstechstuff1131]

You're very welcome. Have fun!

[@athenarobbins2515]

Your calibration video was terrific!!! You're down-to-earth, to the point, and very simple to understand. It was a great help to me just starting out and I very much appreciated it. Thanks is all I can say, but I really do mean it!!! Have a blessed day yourself too and look forward to learning and sharing back someday soon. Cheers!

[@pink7ukusa]

Truly remarkable how you explain this technique in such an informative way, thank you so much for teaching us something which is never really discussed but is so very important to photography....well done brother!!!

+John Matys thank you for watching and I'm so glad this has helped you!

[@Ravindra.Dubey1]

Hats off to you Dave! It's so useful explanation that you deserve to charge for this video. In fact there are people selling software and hardware (like Pyramid!!) to give exact same result, but here you have helped for Free, that too giving an in depth logical explanation. You so rightly stated that in fact it's camera body (firmware) calibration rather than the lens calibration. Don't worry about ignoRants trolling this video, as they rant only because they lack basic understanding of science! Regards mate! God bless you...

[@daveknowshow]

Amen brother! I wont let them get to me when I know full well it works and so does a multitude of other people who have watched and used this video. I dont charge for any of my videos but they are monetised so I can make a few pennies each time its viewed. it helps me when people share the video on their personal social media page or other places. and of course commenting liking and subscribing also helps my channel grow. thank you so very much for taking your time to watch my video and leaving such a nice comment! be bless my friend peace love and respect to you and yours!

[@barretojrj1]

daveknowshow, Thanks a lot, i purchase a used Canon eos 7d and i was going kuku!! with the soft focus, checking all the internet for a solution and believe me most of the stuff i heard some make sense other were too complicated to understand or there was a need to buy a calibration tool. Until i found your video IT COULD BE SIMPLER A REGULAR CONSTRUCCIÓN SQUARE HA!! AND YOUR SIMPLE TO UNDERSTAND WAY. I Started with the 18-55 kit lens i told myself if it work with the kit lens then everything will be alright, so you know what the results were super, now i'll do the rest of my lenses thank you very much for taking the time to make this video, Gracias!!! hasta la vista!!

[@daveknowshow]

so glad it helped you please share the video with friends so others can benefit from this simple fix. this method can also be used on many other brand cameras and many other model cameras. thanks for the kind words.

[@myhealthtoo]

and lastly do you think that 70d is better than 7d?

[@photobobjohnson]

Dave i am guess n but could it be that once a year we should change the lil battery in the camera. My reason it could be giving a lil less current and causing the issues.?

[@rogerbeltz2370]

Very well explained but I do wish the clarity of the video were better. One question: What do ya use to support the carpenter's square? (A little off subject, but still curious). Oh one other thing, does it make any difference whether you perform these tests through live view or the view finder? Thanks

[@daveknowshow]

a book will hold the square up. live view worked best for me and my old eyes but you can use either. sorry about the video quality this was done many years ago when everyone pretty much shot in 720 P cause that is all that was available.

[@eyedream-gf]

great explanation. thanx

[@daveknowshow]

always happy to hear when these videos help.

[@williamandrus4704]

Dave I was getting ready to embark upon a complicated return to B&H photo in newyork. My 7D out of the box has been soft, and I was very upset and wondered what was the problem. I actually just received the RMA# from them when I stumbled across your video....A LIFE SAVER! I will post how my two lens calibrations go once I've completed them .....Thanks so much again for sharing this information. You should be working for canon....why did they not share this information with you in the first place??

[@NathanSchiro]

I am using a 50mm prime lens and I am having trouble with too much variability (as in, out of 5 shots, some are focused in front of the subject and some behind). Any advice?

[@daveknowshow]

yes calibrate the lens over and see if that helps. if not go old school and use manual focus. manual focus is 100 times better all the time,

[@cam62blue]

Thank you for this, I am have awful focus problems with my new 80d and my 100-400mm Mk.2 lens I use for aviation photography. I'm going home tonight to follow your video.

[@daveknowshow]

I'm sure you will get great results, however aviation photography is really tough at times. there is a bit of luck involved at least it proved to be in my experience. the calibration will help.

[@cam62blue]

Thanks a lot !!

[@synapsecracklepop2948]

So... I have one tutorial that says have the lens at max aperture for this process and another that says it has to be at maximum focal length, which decreases the aperture. It also states that for this calibration to be right, you have to be a minimum of 50 times your focal length distant from the subject. I notice you're indoors with a 70-200mm and don't change your distance from the subject. I'm calibrating a 100-400mm to a 7D (don't know because it's second hand but new in box, whether or not it has this firmware update. It was manufactured in 2012, so I'm assuming it does). It's raining, of course, (I'm in Seattle), and I would rather not try to go outside. I really like what you're doing here with the Square... very smart. I'm just conflicted about whether or not to do it your way, or the book's way. All I know is autofocus isn't working right and my pics are all fuzzy... but not everywhere... just on my subject... so I eliminated everything else... body mechanics, shake, settings. It's clear I need to do this. HELP MR WIZARD!

[@daveknowshow]

+synapsecracklepop2 sorry for the delay. I would suggest doing this at a longer distance that allows a quality manual focus at both 100 and 400mm that shows the numbers and lines on the framing square used filling the image frame as much as possible. then switch to auto focus and calibrate. then test the results at various distances. I use a wide aperture 2.8 to render a thin depth of field at 100 as well as 400 with in reason when doing the calibration. I will say that you may get best results calibrating from further away since most of what you will be shooting will be further away. I'm assuming you will be shooting birds and such. keep in mind birds flying at you or away from you are extremely difficult to capture tack sharp no matter how well your auto focus responds. auto focus is a great addition to shooting photography that is moving. if your shooting still images manual focus is your friend and will deliver far better results if you have good eyes and a steady hand or tripod. most everyone that has used my method has had great results. the only ones who seem to complain are the ones who spent to much money on a high dollar calibration device or they sell those high dollar devices and don't like my simple way to do the same thing at less cost. I hope you have great luck with this fix. let me know if you have more questions.

[@shanehinds1940]

I found this information very useful! I've had issues with soft focus on a couple of my lens and this helped fix it. I did find this video hard to follow during some portions because of the extra time for unnecessary steps. For instance when you say push the "Info" button you don't then need to count the buttons both up and down to the only button that says "Info". I personally find this annoying. However like I said the actual content was very informative and you seem very knowledgeable in the technical details of your gear. Thanks!!

[@graphicartdude]

Thanks a bunch for this easy to understand video Dave. Can't wait to try this out.

[@marcandsebe]

I don't mind your slow voice. I think you have explained it very well. Thank you.

[@troilus12]

Thank you! Thank you! Thank you! Clear instructions and I already had a framing square. Very much looking forward to getting out today to test out the adjustments. I think I ended up at -10! Again, Thank you!

[@daveknowshow]

glad it helped.

[@alanbyrd]

If the focus had been off at 70mm, would you make an adjustment there also? Or, would you average? Or....just leave it alone? I noticed on another video where there was a choice for Wide and Telephoto settings, but I'm sure that the camera involved was not a 7D. Thanks in advance.

[@daveknowshow]

generally you set and check at all focal lengths adjust as needed. if nothing moves camera stays in the same place, point of focus stays the same distance then they should be with in tolerance. if they are still far off from each other send it in for factory cleaning and adjusting because something is seriously wrong. with that said keep in mind that we are doing this to calibrate " auto focus " and auto focus will never render the most optimal artistic focus as manual focus will. when and if you have time use manual focus. additionally if you know you use a specific lense for example the 70 to 200 2.8 to shoot portraits at 85mm from a distance of 20 feet away from the subject then you can calibrate for those setting. however that is beyond the scope of this tutorial and is a practice used by seasoned photographers who are aware of the risk and have a keen eye to be on the look out for errors as the shoot is progressing. in doing such a set up a photographer may set a lense to bias a forward focus when pointed at the eye closes to the camera or vice versa depending on what they wanted full in focus. " from the closest eye to the camera and infront of that eye or from the closest eye to the camera and behind that eye. keeping the eye tack sharp and allowing the softing to bias one way or another. again this is best done using manual focus in controlled settings. I hope I did not get to far into this topic as it can be very broad in scope of what acceptable focus bias is and how best its used and when. thank you for your great question!

[@JimDurfee]

Most newer camera's allow you to micro adjust a zoom lense at the low end and also at the high end......

Thanks Dave. I too have had tons of issues since the update, including this "cannot recognize battery" error since the update. VERY disappointed with Canon. Called and was told that they hardly hear of this issue, and wanted me to send it in for adjustments (at $200 bucks). Even though I see tons of posts about it. Anyway, major issues with focus since, and after trying your way, feel tons better. I've tried the "remove battery"/hard reset options, and no results. Just went through and adjusted ALL of my lenses (though I'm more concerned that it took a +25-20 to get them all right.) That can't be good, but it'll work until I find someone that will take a look at my camera...

[@markballi4805]

very informative Dave. I have a 100 - 400 mm Canon USM II L series lens. how far away from the lens does the square have to be? Thanks again.

[@daveknowshow]

i was about 15 feet away with the 70 - 200 id go twice that with the 100 to 400

[@daveknowshow]

I feel strongly this will help fine tune your focus issues that come about due to extreme front / rear bias focusing. keep in mind auto focus is best used for situations where manual focus is not practical. manual focus is the very best and most accurate focus with the most control. when ever possible for best results you should be using manual focus.

[@dorothykufeji944]

Thanks Dave. Great video. My question is: Will this method of calibration work for my 50mm f/1.8 which is not focussing well with my 7D? Or is it just a peculiar problem with the lens

[@daveknowshow]

yes it will work with the 50mm1.8!

[@johnmbouchard]

Does this then work in all modes, Auto, portrait etc, or do you have change to the CF, option when shooting?

[@charlierussom7439]

Dave, I watched this video about a year or so ago. I found it quite interesting BUT did not try it out. I am having major focus issues with my 18-135mm lens and my 100-600mm lens. I may have caused the problem but it is driving me crazy. Actually stopped shooting for awhile. I am currently on vacation and have started to use manual focus. I bought a docking station (I think that is what it is called) tried to calibrate my 600mm lens but it was too complicated to figure out. Guess I am getting to old. Question is, can I place the square/yard stick in one place and use it for all my longer focal length lenses? I have a 80-300mm also. I really need to get this fixed. I hate the out of focus shots.

[@daveknowshow]

yes it works with all focal lengths. make sure your diopter adjustment is set correctly. there should be an adjustment knob beside the eye piece when you adjust it for our old eye sight do not look at the image instead look through the lens at the reading at the bottom iso, shutter speed, aperture, and exposure meter. make sure you adjust the diopter so those readings are in focus first. then calibrate your lens for sharp focus.

[@charlierussom7439]

daveknowshow Thank you sir! I will check my diopter first. Today I used manual focus and only AF for scenery. I will let you know how it turns out.

[@richarddriessen4128]

[@biggun98056]

Just do like I’m in the process of doing is switching to Nikon from canon I don’t like soft focus rather

[@daveknowshow]

I prefer the canon for now and focus is tack sharp once you calibrate. for your information even nikon has this same issue. they all need calibrating from time to time this is why the include a calibration adjustment with in the camera body.

[@JimDurfee]

I've been doing micro adjustments for some years now somewhat like this and it works perfect! All my lenses are tact sharp right where I focus. I use a book and a tape measure on about a 45 degree angle next to it and dial things in and presto! done deal!!!!!! (I don't use live veiw though but always the view finder in oneshot with the center focusing box).....just my way, but it works for me.... I actually just made a video showing how I do this and tell people you don't need to be a friggin engineer to adjust auto focus! LOL You explain it though a lot better than I do in my video!

[@daveknowshow]

this has been my most popular video of all my videos. thanks for watching and sharing

[@Guoenyi]

Micro adjustment cannot affect live view shooting.

[@foxfit4904]

The quality isn't the best but excellent info in this video. Good work man.

[@GeorgeTorres]

I think you can get a better focus if the shutter was at 250. There is hand shake when you hit the shutter button. I am saving this video o my favorite very very helpful. But In a bright room with some strong sunlight you can use ISO 100 and us shutter speed 250 or higher. Freeze any motion... But I do think you nailed this on the head and I will try it. Thank you

[@daveknowshow]

George Torres if your focus issue is related to camera shake then your correct higher shutter speeds will help fix that. this is for when your using all the methods to insure no camera shake and the lens to camera calibration is out of calibration and causing the focus issue. this will fix that issue. this will not fix shaky hand issues, ultra slow shutter speed issues, or subject moving issues. thanks for watching and commenting. :)

[@GeorgeTorres]

I under stand but I think I saw your camera move a little or the strap when you was micro adjusting at -1. Anyhoot. I have never seen the expensive apparatus. That is actually more expensive. What is it called. I would like to google it.

[@daveknowshow]

George Torres just google lens calibration equipment there are many out there.

[@GeorgeTorres]

Thank you

I have a high end 35mm contax camera with Carl zeiss glass that I bought new, and barely used it. Paid big money for it, then they came out with digital. Makes one hell of a nice paperweight. Not sure what to do with it. Maybe it'll be worth money some day. But the road to someday leads to the town of nowhere.

[@williamreymond2669]

Minus 2 out of a range of -20 to +20? That's good eyesight. That's good shooting. Well done. If you can figure this out on your own without instruction? Even better.

[@daveknowshow]

figuring things out is what I do best. its both a blessing and a curse. I'm just glad that so many have been able to benefit from my discoveries.

[@julieholland9639]

dumb question but I have a 7DII and wondering if you go to the left or right for back focusing lens

[@davidharvey4059]

Minus microadjust moves the plane of focus back and vice versa, so if your lens is focusing behind where you want it to you would use +, to bring that plane of focus forward

[@BisonWorkshop]

i need to ask. can i hook up a wireless mic to my jvc camra like you have. if so. how?

[@daveknowshow]

+Bison Workshop I don't think you can on the jvc. no mic input plug on that model jvc.

[@BisonWorkshop]

it will when im done. ill just add one

[@daveknowshow]

make sure you add one that has a switch built in to turn off the one on the camera. that will help noise issues from running two mics at the same time. I been thinking about using an additional audio recorder for the audio tracks. just a simple unit like a sony model no. icd-px312 bought it at walmart.

[@BisonWorkshop]

+daveknowshow i desided to do my sj4000 instead. i will use a jack that cancels the other mic when something is pluged in it. so if i was going to do this too the jvc thats how i would do it, but i dont want to mess with it. on the sj4000 i will remove the mic in it. and i just bought a second one just incase i mess it up with braking it while taking it apart. im not worried about my work on the electronic part. thats a breeze but we are talking about cheap plastic. loli will be videoing that mod. when i get the new one.i also ordered this to try out. www.ebay.com/itm/252123267158?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

sweet

[@travelerfourever1347]

Very informative video. Great job, thank you.

[@daveknowshow]

+Travelerfour Ever thank you for watching and sharing my video. I hope you have a great Christmas holiday!

[@chirvisuals]

Thank you so much. it's so informative video. Lots of love from India. I want to ask something. when I go to Adjust by lens option then if I click info. for getting the info of the lens like 18-135mm, so many 0000000 like this comes which says review/edit lens information. I don't know what is this. Please help. I am using 7D mark2.

[@daveknowshow]

the 7d mark 2 should automatically know the lens as long as the lens is hooked up to the camera. when you press the info button on the left side of the camera you should go to the calibration screen where you can adjust the bias of the point of focus. whether its in front of behind or spot on the center selected point. I hope that makes sense. you may need to watch the video again and look at where the info button is at 6 minutes 23 seconds into this video. be sure your hitting the correct button and your screen looks like mine. I hope this helps and thank you for watching.

[@chirvisuals]

daveknowshow sure. I will look it again. Thanks again.😃

[@daveknowshow]

lots of love and respect from America, peace and love be with you always.

[@Omniklix]

thanks for this. very informative. i learned something new and guess what i aint giving canon not a one cent for doing this. thanks.

[@daveknowshow]

for sure save that money and use it for other stuff. I'm so glad that this method has helped so many people.

[@hbo1230]

Very helpful! Thanks for sharing!

[@daveknowshow]

happy I could help! peace love and respect, Dave in Virginia

[@BaddaBigBoom]

I have a Sigma 17-50 F2.8 and have had focus issues with it on my 7D ...will try this. Thanks a lot.

[@daveknowshow]

you will be happy with the results! I have a 17 - 55 2.8 canon lens that i used this on as well and it worked perfectly.

[@elbowroomtube]

Good video. I have the same focus issues with my 7D. How do do set up your focus points so that everyone in a group shot is in focus? I find this confusing. Thanks.

[@daveknowshow]

it is always a challenge when doing group shots. a down and dirty rule of thumb to get the job done is first make sure the focus plane of the camera is parallel with everyone in the group. a group of 5 people on a stair case one on each step going up or down would NOT have everyone on the same parallel plane if shot straight on. the person in front could be in focus and the one in the rear would be out of focus. so avoid that! also stop it down to f9 if possible or some variant. in other words dont shoot wide open at f2.8 your depth of field will be shallow. stopping down to f5.6 you would have a thicker depth of field at f9 it would be even thicker! so stopping it down will help get everyone in focus or at least increase the odds.

[@fredferris4877]

Thanks Dave for the video. I use a Canon 5D Mark II, does your system work with this camera also? Fred

[@daveknowshow]

yes!!! works great!

[@TheModernDayPirate]

Great video I will be doing this to my 70 -300 first chance I thought those micro adjustment calibrating chart gizmos would be a waste of money Thanks for the info I will let you know my results!!

[@joserojas7123]

Does the new firmware 2.0.5 fix this problem?

[@waymol]

Hi Dave,love your style & easy to follow Video, will the 7d memorise settings for Canon only Lens or will it work for say a Sigma 105mm f2.8 os Macro? Best wishes for 2014.

[@MarkMcLT]

Good stuff. And Batman/Lost In Space are a bonus! :)

[@daveknowshow]

yea i'ved learned to shut the tv off although i still forget the radio at times. lol

[@longd]

at 12:55......da da da da da da................Batman ! I love it! Thanks Dave I can't wait to do this for all of my lenses...

[@tonygrech1232]

good video. Thanks. I think its better to a use a timer to take the photo so that you can remove any shake when you are taking the photo

[@daveknowshow]

Tony Grech camera shake when on a tripod is near non existent. the amount of shake would not come near the amount of depth of field at f2.8 which is what this lens is. even at f1.2 if you have a lens that fast using a tripod will result in very little camera shake that will simply not affect this calibration process. if your shooting hand held then keep your shutter speed up high enough to counter any user camera shake. it blows my mind that so many people insist on a timer or remote shutter release to limit camera shake and those same people us the "focus recompose" method of shooting images. it simply does not affect point of focus to the degree to be able to see it.

[@18primo]

How you do to focus on live view so fast? On mine it take some time to focus

[@daveknowshow]

I don't have any issues focusing fast on live view. make sure your battery is fully charged. that could be the problem since it takes a lot more power to focus during live view than when live view is off.

[@18primo]

@@daveknowshow Thank you for the response. I just did that and it still was the same but I think the problem was my lens because I change my lens and it focus way fast thank the one I was trying first

[@daveknowshow]

@@18primo dirty contacts on the lens. clean them with an eraser from a pencil and or a qtip dipped in peroxide.

[@18primo]

@@daveknowshow I will do that thank you so much for your response and help

[@daveknowshow]

@@18primo glad to help

[@nigelchilds4726]

How far away from the camera was the focusing point, is it a crucial measurement?

[@daveknowshow]

not that important, more important that you keep it the same for wide or zoomed testing. however, I generally try and stay just over the closest focusing distance of the lens. for example if my 70-200 has a close focus distance of 1.4 meters just over that is where I start my testing. after setting up the calibration I may retest at the mid distance ie: half way between the closest distance the lens will lock focus and the furthest distance just before infinity. if my lens closest is 1.4 meters and the furthest is 10 meters "just before infinity or the circle of confusion" half that would be around 5 or 6 meters. so I test at that distance. which is not easy to do from the camera back and is better done tethered to a laptop or some larger viewing screen. hope this helps.

[@BIGAACE]

Great video

[@daveknowshow]

thank you!

[@robertskeide9954]

Thank you very much for an excellent instruction to this problem!

[@daveknowshow]

glad to help, thank you for taking your time to watch it

[@kristinas1429]

This Was The best... Love when you show everything so good. The Best The Best. Love this!!!!!! Thank You =)

[@daveknowshow]

so glad this helped you. I hope you will share my video so others may benefit from this simple and effective method of fixing a very common issue. this will work with all DSLR cameras no matter what brand name it is. thank you for watching my video.

[@MrRenoman2011]

Thanks so Much Dave much appreciated! This will help me allot.

[@daveknowshow]

sir the thanks go to you for watching my channel! thank you so much! I'm sure this will fix your focus issues.

[@lonelyboatman]

Great video.. gonna try it on my Sigma lens.. Thank You.. forget trolls..

[@daveknowshow]

thanks for stopping by

[@chuckrossi]

Will this work for the Canon 70D?

[@daveknowshow]

+Charles Rossi yes it should work with any DSLR camera brand

[@lindaholder2225]

What mode are you adjusting at?

[@daveknowshow]

it don't matter as long as its not a custom mode. I shoot in manual mode 99% of the time. I'm not 100% sure what would happen if you calibrate in a custom function mode.

[@graphicartdude]

Dave, would you advice against doing firmware updates?

[@daveknowshow]

my feeling is "if its NOT broke why fix it" in other words do your research on what the update will do for you as a photographer or videographer depending on what you use the camera for. if the camera is working fine then why mess up a good thing? if the update is gonna add some bells and whistles that you just have to have then go for it but maybe wait 60 days to see if there are any complaints or issues that come along with the update.

[@graphicartdude]

***** Exactly what I was thinking. There were a couple of features in this 2.0 update I was interested in, but not sure it's worth the risk. I have been noticing a lot of my lenses haven't been very sharp (even with fast shutter speeds and correct technique). Your video should help immensely. Thanks again.

[@daveknowshow]

glad to help! :)

[@freelancereports7244]

Thanks for the vid. Really helpful and very informative! Will defiantly click on the add every time I visit one of your vids ;) (I think I heard that Batman theme in the background lol)

[@امیرطاهری-خ5و]

wow . tanks mate . it was great

[@daveknowshow]

happy you will have great results.

[@noelalbino7347]

This is very helpful! Thank you so much!

[@daveknowshow]

I'm very glad you found this video. I know you will have very good results applying this method. I hope you will consider sharing this video via your social media outlets to help other photographers learn about this money saving technique. not to mention so they can see just how far out of calibration their camera / lens set up may be. this technique can be used with just about any brand camera that has the adjustment option in the menu. thanks again for stopping by.

[@johnnyeightpence722]

Just Thanks !!! Will adjust my body accordingly, too these days.
