Sigma 18-35mm f/1.8 "A" Review

[@falcon048]

Just want to add a few things: 1) Image Stabilization. You don't need it at 17 to 35 mm. The longer focal lengths need it. This keeps the cost and weight down. 2) The Vignetting. This lens is for APS-C or cropped sensors. If you put it on a full frame Camera, as the author of this video did, you will get vignetting. That really isn't the fault of the lens because you get no noticeable vignetting on a cropped sensor camera. 3) This Sigma lens can be updated via the firmware through a docking station (sold separately.) It also lets you fine tune the focus across each major focal length up to four different focal ranges for a total of 16 separate adjustments. 4) Low light autofocus performance has more to do with your camera's capabilities than the lens. As the camera has to figure out what object is out there to focus on. The lens is just feeding the sensor what its optics allow through. I have had this lens for some time and use it on my D500. Out of all my lenses, this is the best. I have not had the issue of AF mistakes as has been heaped on this model. I have to wonder if it is because most people do not calibrate the lens to their cameras before serious use. I can see it missing autofocus if the lens is forward or backward focusing too much. Thankfully, the D500 allows for autofocus fine tuning. I also used FoCal to calibrate the lens to the D500.

[@markharris5771]

Had this lens for about 2.5 years and it's easily my most used lens, never had any hunting or inconsistency with it at all. This is much more likely to be on my 7DII than my 24-70 to be on the 5DIII. I do keep the software up to date though and undated it before fine tuning it for the first time so I may have by-passed these issues in that first update. I know I did bypass back/front focusing issues on the 150-600 Sport by updating its software straight away. That hub is a fantastic bit of kit.

[@KPAki1Ler]

Would you recommend this lens for a 70D? Did updating it reduce the need to calibrate the focus extensively? thanks

[@markharris5771]

James Chisholm James Chisholm I would recommend it for any cropped sensor camera, it really is that good. I always like to calibrate my lenses, but usually it is done in camera rather than in lens. I don't remember this lens having as major update as the 150-600 but small ones as I've gone along. I've never had the focusing inaccuracies talked about in this video, but that may be because I do calibrate it, but these calibrations were more "tweaks" than major overall. I know I did make some quite radical changes on the 150-600 but not on this lens. Allow yourself half a day to do it and you won't regret it. I have 4 good quality L lenses, one in the range of this lens (my 16-35 f4) and at equal setting the Sigma is better.

[@fatmata141]

Mark Harris hi. Can you please email me or dm me? I have a question. Many thanks x

[@MicLoveMedia]

This is probably the most detailed review Ive ever watched on any product. Good job!

[@DarrenMiles]

Thanks Mic!!!

[@NarekAvetisyan]

Great review Darren. Love this lens. I hope Sigma comes up with a Mark II version of this lens with Optical Stabilization, faster focusing and Weather Sealing.

[@peterkoch3116]

Optical Stabilization, can not be done on this. Impossible.

[@CaptainVapes]

THESE REVIEWS ARE OUTSTANDING, putting its pros and cons into groups and marking out of 10 really makes it great for viewers, as I trust your judgment going off your knowledge and experience, I'm so sick of other reviews being mixed and not knowing what they think, if I need to know how image quality is in yours I know it's close to end of review lol, which helps when looking for lenses I don't need great focus speed for, as I use a lot of wide angle for landscape and focus speed I don't really need

[@keithbrown454]

Wow!! In all honesty, this was one of those most in-depth reviews I have seen on this lens. Outstanding video and commentary!

[@DarrenMiles]

Wow, thank you sir, much appreciated!

[@keithbrown454]

Darren Miles have you done a review on the Sigma 50-100mm 1.8 lens and why do you believe it took a 3rd party lens manufacture to make an an outstanding APS-C lens for Nikon and Canon. Why didn't Canon and Nikon make that lens first in your opinion?

[@DarrenMiles]

I have - kzbin.info/www/bejne/qpindKKEm7qFpJY - Overall, Sigma has done an amazing job with some ambitious ideas - specifically wide aperture zoom lenses - I'm a big fan, but my experiences with the 50-100 were a bit of a mixed bag...

[@eliaspap8708]

Wow! Im glad im not the only one in love with this lens! Im using it on my Fuji XT3 via a Fringer pro 2 adapter and it really is stunning, its like having 3 different primes, also the focus accuracy is much better with a mirrorless sensor, well I dont seem to have any issues with AF so far, the you may want to try putting this lens on your full frame body, at 35mm there isn’t any black edges, ofcourse there is some vignette but wow! the images are truly astonishing and very Artistic.

[@LoverofAllThingsGood]

Thanks for the video ... just bought one can wait to use it ASAP!

[@BabyBackManiac]

Loved the review, Darren. Very helpful. Thank you for taking the time to make it. I'm trying to decide if this would be a good choice for video. I have an 80D and often use a shotgun mic and I'm wondering if the autofocus is loud? I've seen some videos online that make it sound like a garbage truck and i can't imagine it's that bad or you would have mentioned it. What is your experience with that? BTW, Thank you for your even handed reviews. I really like your channel (and Tony N.'s) because I feel like you guys do a good job of presenting all sides.

[@charifhaddad5886]

Will look forward for another great review about the new Sigma 24-105mm f/4. Thank you Darren

[@TheGrace2Speak]

Outstanding review!!! Highly educating. Exceedingly articulate - impressive lexicon. Thoroughly evaluated. Great breakdown of ratings, i.e. optical performance, overall value, etc. Loved the analogy in the Intro about Hyundai - it made it accessible to understand the value of the company; hence this product. Wonderful to watch from beginning to end. The entire 12:07 minutes was well-worth spent. A very credible review. Thank you for your investment in time to make us more adept in understanding the value and power of this lens.

[@DarrenMiles]

That could quite possibly be the nicest thing anyone has ever written about one of my reviews. Thank you very much!

[@TheGrace2Speak]

It was spoken from the heart, in gratitude and appreciation for your investment in others; many of whom you will never even cross paths with. And by the way, not only are we grateful for your time, but likewise, the quality of your video was outstanding - as commented by others. Just an overall class act! Can't say enough - thank you, thank you, thank you!

[@DarrenMiles]

Grace M. Stinson Wow! Well, thank you again, and if you haven't already, please don't forget to subscribe :-)

[@mikeresnik]

Thanks for all your great reviews! I have been getting more into the video side as of late and its so nice to find well done reviews of lens that include a video aspect.

[@monkey401]

I also had the sigma 18-35 in the past month on a 7D before I recently upgraded to full frame and your review is spot on with the AF. Besides the AF issue of the 18-35, it is easily my favorite walk around aps-c zoom lens on a crop body. I'm now shooting with the Sigma 35 1.4 and look forward to your review. You have one of the best equipment reviews online. Keep it up!

[@DarrenMiles]

Thanks Daniel! Much appreciated!

[@howardkahn717]

Excellent review........It will work on a Sony full frame because the a99/2 and a99 "A" Mount models have an aps-c mode........

[@Twobarpsi]

Just bought one! It's amazing!!

[@TEMTECKPHOTOGRAPHY]

Just ordered one off of the Mighty Amazon.

[@sawyerh.923]

Canon did make an "L" type lens in this focal range for cop sensors. It's the EF-S 17-55 2.8. It's also about the same price point.

[@DarrenMiles]

Hey Dan, thank you for your comments. The 17-55 is indeed optically excellent, but I wouldn't put in the same league as the Sigma 18-35 or any of the L lenses from canon - as it's poorly built, not weather sealed, doesn't include a lens hood or a case and it's also a dust magnet, moreover it runs about $80 more than the Sigma. But all of that is forgiven when you see the results, as they are pretty darn good! You're right though, optically it's about the only serious lens that Canon ever came out with for crop frame bodies - but the rest of the EF-S line is definitely targeted toward consumers - the only other exceptions to that might be the EF-S 60mm f/2.8 Macro or the EF-S 15-85...

[@sawyerh.923]

Well I've never heard anything bad about build quality. And I thought the Sigma wasn't weather sealed either. Also I wouldn't really consider the accessories it comes with to define a lens in anyway. That being said, I've never used either so you'd probably know better than I would how they perform compared to L glass. I just think if Canon made L glass for crop sensor, then that would be have the red ring.

[@steezeyboss]

I LOVE this lens

[@jpjacobsenbr]

0:14 Yes, there is something in the water of Fukushima. It is called: Nuclear Radiation.

[@simenrogne]

Fantastic review! Definetly going to get one for my D7000.

[@DarrenMiles]

Thank you sir! It's a great lens!

[@danielbarrera6880]

Hi Darren, The quality of your excellent review , with no doubt prompt me to subscribe. Could be very interesting to me an other Art Sigma lens , the 24-105 f/4, I look forward an other great review from you about this interesting lens. Thank you very much Dan

[@DarrenMiles]

Thanks Dan - that lens is on my radar.

[@Design39media]

Phenomenal review! I have the 50mm 1.4 for Nikon, and I have been watching this one as my next purchase. I am pretty sure I have made up my mind. Curious, what lens did you use to shoot this video? Was very impressed with the video footage you showed from the 18-35. I plan on doing alot of video shoots with this lens.

[@villegas24]

Just ordered ,it I can't wait to get this!!!

[@MrMatthieuC]

In your opinion, would this pair up well with a 70-200 f2.8 and maybe a 50mm prime?

[@DarrenMiles]

Matthieu - if you're using a crop sensor camera then yes, it would make for a great combination.

[@MaherBaba]

+Matthieu Cramers this is exactly want I planned to get, Matthieu I raise my glass to you

[@fredmiu2001]

well done again, Darren.

[@DarrenMiles]

+Fred Miu Thanks Fred!!!

[@ThatSneakerGuyLA]

Hey Darren, I am about to purchase a 70D and now have made my decision to buy this Sigma lens. I have a question about your video footage that you used at 7:12 , are you using a tripod with wheels, I'm trying to achieve the same smooth moving footage for a project. Thank you!

[@DarrenMiles]

It was a camera slider - from cinevate.

[@CloverStarz]

I dont like third party but this is something caught my attention, smart sigma thank you for this, it will replace the kit lens, hopefully nikon and canon will listen.

[@Redbull357]

what lens did you film this with? thank you!

[@sonikabhattaraikhanal1207]

The video review quality is so impressive , if u dont mind can i know what kind of lens and camera you use for this video review ?

[@fumfumkoproductions331]

Great review! Very helpful :) What lens did you use to shoot this video? It looks great!

[@DarrenMiles]

Thank you very much! Probably recorded on a 5D mark iii with a 70-200 lens.

[@jangolhasaapso4070]

absolutely brilliant quality review video :) i am gonna get 11-16 mm tokina because of your review.

[@DarrenMiles]

Thank you! Why not the Sigma?

[@jangolhasaapso4070]

Darren Miles but i am going to buy d7100 and i found sigma lens is really good 18-35 for portrait i guess. what would you recommend lens for landscape. could you please share with me your opinion. thank you darren.

[@DarrenMiles]

Jango LhasaApso On a D7100, the Tokina 11-16 that you mention is really good, as is the Sigma 10-20 for landscape - especially on a crop body like the D7100. Not sure I'd use the 18-35 for portraits - perhaps for weddings or as a general purpose lens or photojournalism because at 35mm its the equivalent of 52.5mm on a D7100 (57.6mm on a Canon Crop Body) puts it on the short end of what is generally considered suitable for portraits (85mm - 135mm is "generally" considered portrait lengths.) That said, rules are always made to be broken :-) For example I LOVE portraits at 200mm and 300mm...

[@jangolhasaapso4070]

Darren Miles thank you for help darren. i finally pick my lens. i will get tokina 11-16. i would love to take portrait as well with sigma. but i am not on a bussines for wedding or etc. just for holidays. also can i ask something about cameras. also i am getting sony a77 as well. do you recommend Canon 7d or a77 ? thanx.

[@ladefreakndah]

Wish they would come out with these for the Panasonic/Olympus micro 4/3 bodies.

[@zuzkarory]

hi. thanks for the review. i'm wondering for film making purposes, (ASIDE FROM LOW LIGHT ADVANTAGES) if f1.8 is very useful at 28mm or 35mm? What does a wide shot with shallow dof look like? Is it a useful look? A common one? Its interesting and I ask because the conventional idea I think is that wide angle means you generally stop down anyways. But what if you don't? What does a 28mm 1.8 image look like? Do you think we see this type of shot in feature films? Thanks so much for your thoughts!

[@thinkingoutloud3757]

+PostModern Filmmaking You see all types of shots used in film, just like photo, depending on the type of feel you're going for. I was just watching The Fall (it's on Netflix), and there were shots of the murderer talking in a particular scene, where we were tight on his eyes, but the DOF was super shallow, to the point that one eye was out of focus while the other wasn't. Meanwhile the colors were very balanced and natural looking, not dark or gritty at all. So it just felt strange and twisted, solely on how the shot was composed and the depth of field.

[@kinjat561]

Hi Darren, on a budget here but planning to go with D7100 with this sigma 18-35, do you think it is wise decision? I was using Nikon 35mm f1.8 prime with D3200, although results were pretty good but I wasn't so happy with sharpness, going with this change, is it worth a shot?

[@stilmotionpicture]

Awesome review sir! I love the focal length of this lens and the fact it's f1.8. I have a Panasonic gh4, and I understand about the cropped factor, how would this lens be on a micro four third like my Panasonic gh4?

[@DarrenMiles]

It would be amazing - but you have to get an adapter - Canon or Nikon to M43 - metabonz has a speedbooster that improves both the maximum aperture and shortens the focal length. A lot of video guys use the 18-35.

[@stilmotionpicture]

Darren Miles awesome! Thank you!

[@MichaelJohnsenOslo]

I use it for my GH4 and it's one of the very best lenses for it. With the speedbooster, you're looking at a 25-50mm, so it's a fantastic all-around lens.

[@thebrandonkm]

Wonderful review!!!!!

[@DarrenMiles]

Thank you!!

[@cjr96]

Great review thanks

[@chestudios8742]

Hey, very helpful review. Were the video clips shot at f/1.8, or higher??

[@Rationalific]

Great review! Great lens!

[@dmstudiofoto8784]

Not for full frame should not included as a lack of this lens Coz this lens purposely for apsc. 24-70 f 2.8 lens for full frame as sigma 18 35 will be 24-53 f2.8 equivalent to full frame lens

[@ALJAMMAL83]

Hello Darren, Great Review, I would like to know if the focus issue is solved after using the USB dock fine tuning.

[@DonSolaris]

No. Sigma does not work with Canons. It front focuses 80% of shots. Dock doesn't help since the lens randomly chooses focus point from time to time.

[@ALJAMMAL83]

Thanks for your valuable information, Id rather focus on Canon lenses only then.

[@10399alex]

Great review

[@Banks111]

I feel like Patrick Bateman just reviewed this lens. Good info though

[@METAL4K-UK]

Hi Darren/somebody. Would the long end (being greater then 50mm on aps-c) be suitable for portraits? Im currently using GX80 with Sigma 30 1.4 and want a leap to a 24mp (80D) sensor without buying a load of lenses. Thanks.

[@alainmaftoum5568]

Hi Darren, excellent video. I own a Canon 70D and i love my Sigma 18-35 f/1.8A. I also have canon 24-105 F/4. I am planning to purchase a 70-200MM . Shall i focus on Canon 70-200 F/4 IS or 70-200 f2.8 IS II is more appropriate to crop lens? Is it worth it? I am not a professional only "Amateur"..photographe. who like to shoot portraits.

[@MysteryVibes]

good review! looks like great lens!

[@davidefranchin5441]

I'm thinking about buying this lens as a replacement for the 18-55 kit lens but I am really undecided between this or buying a sigma 17-70 and save money. Speaking of image quality, is there so much difference? And is it the right choice considering that I love landscape photography, sometimes I do portraits or wild photos? I’d really want to make a qualitative leap :/ Love your videos!

[@DarrenMiles]

Thank you for the kind words! The Sigma 18-35 is an awesome lens for a kit lens replacement and is very reasonably priced for what it is. Where it really excels is in low light. So if you want to do any city architecture at night the 18-35 is probably a better bet.

[@mrjohnbaseley]

Seems like a good lens, but the fact you have to buy the sigma dock right off the bat to correct "Auto focus issues" is just downright insulting. What use us it having a lens that is sharper than sharpsville from sharpsvania, when it doesn't even focus accurately?! I can overlook this fact...sorry...

[@PolluxChung]

I waited and waited for years and only got one last week.

[@sergius705]

Hi! You said that you've buyed the Sigma USB Dock for the autofocus problems. I've just got this lens and I'm not happy at all with AF :(. Is it worthy to buy the USB Dock? Any words? Thank you!

[@TheNAK20]

Seeing that the lens isn't weather sealed, would it be fine in humid environments? I'm from the Caribbean and would love to take this along with me on hikes but it's usually very humid there. Apart from the obvious rain and rain droplets, can you explain what weather conditions this lens can't be used in?

[@DarrenMiles]

TheNAK20 I live in Florida - which is practically the Caribbean - and had very few issues with hot and humid environments.

[@0nizukaS]

I’ve been having massive front focusing issues when trying to focus beyond 2 meters with this lens and a 70D through the viewfinder. Did you notice anything of the sort in your tests? I’ve got the dock and have tried my best to fix it. But even after adding +20 on the far end the issue still occurs again and again. Amazingly sharp when manual focusing or using the live view touch shutter though.

[@ericmcfarland4228]

hey Darren, any plans on reviewing the new sigma 50-100 1.8?

[@DarrenMiles]

+Eric McFarland It's on the list... I'm sure I'll get to it eventually!

[@ryanwalvoord]

great review, what song are you playing during the video quality shots? i really like it

[@DarrenMiles]

It's called "Trees" - I got the license to use it off of PremiumBeat.com

[@ryanwalvoord]

Thanks for the response I appreciate it, really enjoy your videos.

[@DarrenMiles]

Thank you sir!

[@janisfarhat9935]

Why does this lens get 45.5 points? If you add 9.5 + 7.5 + 9.5 + 9.5 + 10 it's 46...!

[@DarrenMiles]

OOPS! :-) YOU'RE RIGHT!! Thanks Janis - it must have been late at night when I was doing the math... LOL - 46 - 46 - it's still a Highly Recommended lens!

[@Cidro1000]

Really good review and i like listening to your voice, its just annoying that you bring stuff up like 3 times, for example that there is no OS in this lens and that the focus and zoomrings are very dampened and has good feeling. This makes the video longer and makes people (atleast me) to skip forward in the video. keep it short and consistent :D

[@DarrenMiles]

Thanks Kung - appreciate the kind words - reviews starting late last year have cut waaay back on the repetition and no longer have a recap at the end - based on a lot of feedback similar to this.

[@Cidro1000]

Darren Miles oh ok! keep it up then ;) have a nice day

[@luiscanamarvega]

Please, can you help me out? I purchased this lens for my Canon 7D (not mark ii), and the autofocus doesn't seem to work. It just goes back and forth really fast without focusing when I press the shoot button halfway through. Please tell me this could just be a firmware issue (I haven't updated my 7D since i bought it).

[@DarrenMiles]

Check your 7D and see if the AF says "Servo" - if it does, change it to "one shot" - from your description that sounds like it COULD be the problem. Let me know.

[@sigeamer]

looking into getting a 70D, not going to be a professional nor anything like that, just want to significantly up my quality of photos in everyday life/travel. don't want to have several primes and having to switch them out as i can always miss a moment and such. would this be a bad first lens? would it make sense to maybe pick up a 17-70 sigma first and this later on, or do you think the 18-35 would be useable enough and then maybe pair a 50 prime? and MUCH later on possibly invest in a 70-200?

[@mnalls05]

how does it compare to the sigma 35mm1.4

[@adityaverma062]

darren what about the results with nikon D7200...is better then nikon 70-200 and nikon 50mm prime lens

[@shuolangliu304]

i like this lens a lot but i also have a sigma 30mm f1.4 and canon 50mm f1.8 do u still its worthwhile for me to get this lens? thanks :)

[@mcsabai963]

do you have focusing problem with this lens??

[@Kprawl291986]

I think sigma should make this lens available for full frame at least 15-35mm or 16-35mm would be awesome.

[@TheMoviesVG]

nice video... please the sigma 85 1.4

[@bovver6092]

Will you do a review of the new Sigma 60mm for micro 4/3?

[@tedp9945]

Did the dock fix the focusing issues?

[@jackyye4040]

Honestly, you can't even complain about the focal range because this is suppose to be a wide angle lens.

[@AlexK611]

is this lens made for cropped censors or is it for a full frame ?

[@vickychristmas]

hello Darren, i have tamron 17-50 f2.8 non VC - and that lens sometimes also inaccurate in canon 700d, do u think this is is as equal consistency with tamron? .. i also though about fullframe, but if upgrade i think too expensive... Thx u Darren

[@mdees88]

00:11 There is... Cesium-134, Cesium 137, and Iodine-131

[@SymonSaysTV]

What was that review shot with, lens and camera wise?

[@DarrenMiles]

I almost always shoot with a 5D3 mated to the Canon 70-200mm f/2.8 IS II - usually shot between f/2.8 and f/5.6...

[@SymonSaysTV]

Darren Miles Nice soft bokeh, especially between 1:45 to 3:46 Keep on the good job.

[@emiliocorin]

Darren Miles But is an Aps-c lens, do you used the 5diii?

[@DarrenMiles]

Not to shoot the review, no, we used the 5D3 for that. That said, you *can* attach this lens to the 5D3, but it will give you a huge black sections around the edge of the frame as the image circle of the 5D3 is bigger than the opening at the end of the 18-35... Maybe less so at 34 and 35mm, but it's better to use the lens on an APS-C camera like the 7D, 70D, etc...

[@SurferKroky]

so this WILL work with the d750 ? in crop mode . is it worthwhile getting it for this camera??

[@Mooowafy]

hi Darren i just have got my Nikon D7200 along with sigma 18-35mm and i cant shoot video at all, i have no idea how to set the auto-focus when shooting video makes it impossible to shoot video alone , please help me i thought if ill go for such expensive gears ill be in peace of mind.

[@juevestv]

Hello dont forget to calibrate the lens with the sigma dock.

[@Mooowafy]

+Facundo Carmona that's what I did and it works great now, thank you so much for your reply

[@miroslavkapusta2967]

I have Canon 70D and I want to buy this lens, but I am worried about focus accuracy with Canon 70D. Is it already fixed?

[@jurgenvanhest5676]

@Darren Would you recommend this lens for Conceetfotography? Think of very dark venues....

[@Noksus]

At f/1.8, definitely. The focal length range just is a bit limiting, so you'd need to get closer.

[@JuanLopez-oz9kh]

Which gems do Sigma have, aside from their Art line?

[@DarrenMiles]

Juan Lopez 4 come to mind, the 150 f/2.8 macro, the original 85 f/1.4 non art series (if you can get one that focuses properly) the 50-150 f/2.8 for aps-c (pretty sure that ones been discontinued) and the latest 70-200 f/2.8 ex os

[@patdinco]

A 35mm equivalent of 28-55...in regards to stills, what do you see this lens used for ???

[@sentatesar9429]

Low light, Astrophotography, weddings, landscapes, travel, filming cinematic. It's also worth noting that pro videographers use it on full frame bodies such as 1dx II and Canon cine cameras (when shooting in 4k they crop 1.3x)

[@santomndr5528]

hello Mr. Mile,could you possible tell me ,about the auto focus of lens in disco or low light situation? is it fast and accurate even in low light in case extremly low light like disco? your video is very good,really want to buy this lens after watching this video. Thank you in advance

[@DarrenMiles]

Sanjeeb Manandhar Hey Sanjeeb, which camera body/flash combo are you planning on using with this lens?

[@santomndr5528]

canon eos 550d,t2i

[@dsan45]

Greatvideo

[@freddiemurry]

Did you take any public speaking classes in college?

[@tomgee887]

They make other cameras besides NIKON CANON did you not know that

[@DarrenMiles]

Tom - who was that directed at?

[@ThelleKristensen]

Great review - what music is used during the sample video/stills?

[@DarrenMiles]

Thanks Thelle!! The song is called "Trees" - you can get it from PremiumBeat.com

[@ThelleKristensen]

PB is a great resource :) Can't find it when I search for it there.. Do you know who the artist is?

[@DarrenMiles]

I just went to the site and apparently it's no longer available - it was called "trees" by Nicolas Major

[@MrFrame1979]

did you find that the dock helped with that AF issues?

[@DarrenMiles]

Unfortunately, no... :-(

[@towfiqalam1971]

I want to make video perfectly. so, you can give me a suggestion about Sigma Art 18-35mm F1.8 DC and sigma Art 50-100mm F1.8 DC. which is best for me? plz reply fast.

[@ToggleswitchPH]

Can it still be at f1.8 even if zoomed in at 35mm?

[@DarrenMiles]

Rhys Bond yes it can!

[@alejandrobeltran8409]

How loud is this lens when focusing? Will my camera pick up the auto focus noise when taking a video?

[@Noksus]

It's not loud at all but yes it will if you use the on-body mic.

[@shuolangliu304]

when u meant focus issues u meant auto focus right? because i wanna purchase this lens for filmming and i do manual focus almost all the time :)

[@DarrenMiles]

Shuolang Liu I did mean AF, manual is awesome if you're into film - many a film maker have adapted this specific lens to the GH4.

[@fcoronel1]

Hey did the dock help fix the focusing problem?

[@tuukkap601]

Yeap, wanna know the same

[@sasca854]

It doesn't help if it is being inconsistent. IE, if it back-focuses sometimes and front-focuses other times, no amount of calibration is going to be able to fix that.

I need to replace my Sigma 17-70mm 2,8-4,5 with some excellent quality wide (for the portraits I have a Canon 85/1.8 and Im using Sigma only for the 17mm) lens for APS-C sensor, i this a good one? I will shot music concerts in the nights and weddings. I dont know if to buy this one or some not zoom lens, I really like how is 85/1.8 sharp, and I afraid to buy any zoom lens if it will be sharp enough... And what about focusing, sure its fast, but its accurate, i read some bad stories...

[@DarrenMiles]

Jaromír Adámek Hey Jaromir, I have not used the 17-70, but if you're shooting concerts and if they're indoors and at night in a club or something, on the wide end f/2.8 is fine, but f/4.5 might require you to bump up the ISO for a proper exposure, of course, if there's heavy stage lighting, it probably won't matter... I'll try and get around to that lens at some point in the future...

Kudos to SIGMA... Thank you...

[@mohammedjasaam]

Thank you for this demo video I have a question, if possible I have the following lenses from Sigma 8 mm f / 3.5 Fish Eye Circular 10-20 mm F / 4-5.6 18-300 mm F / 3.5-5.6 C 50 mm F / 1.4 A 105 mm F / 2.8 MACRO My question is Is that the lenses above what compensates for lens Sigma 18-35 mm F / 1.4 A In terms of efficiency and sharper pictures? Or do I buy another lens to complement the series lenses have? What are the lens that you should buy it?

[@DarrenMiles]

Mohammed Jasaam Mohammed Ali Mohammed - the big thing about the Sigma is the f/1.8 aperture throughout the zoom range - granted it's a small range - but the image quality is nearly as good as having a few primes. I think it could sub for several of these lenses, but certainly not all of them.

Darren Miles Thank you ... and got the idea

[@CostaReall]

Something in the water at FUKUSHIMA! HAHAHAHAHAHAA

[@thisisguitar1]

I couldn't quite believe I heard him say that...

[@DarrenMiles]

It was an unintentionally insensitive comment, I meant it in the most traditional of senses - in other words when I said it, I meant it as a compliment with regard to the good things going on at sigma, not about radiation from the quake, tsunami, or fallout from the nuclear plants. It's regrettable that it's been interpreted that way,

[@CostaReall]

But I loved it

[@thisisguitar1]

Don't worry Darren, it is unusual for a traditional saying like that to ever have the possibility of an interpretation like that! Taken as you meant it I promise. Lol at Alexandre!

[@incomprensible01]

hi is this lens good for event photography?

[@BlueBoyof08]

Is this true that you can use this on a full frame? only at 35mm though?

[@DarrenMiles]

BlueBoyof08 Yes! You still might get some vignetting though...

[@azizulzulzaha]

will it autofocus on D5300? (been a long time not follow update on DX lenses)

[@DarrenMiles]

It should, Sigma makes a Nikon version of the lens with will AF support - after the firmware update with the Sigma dock...

[@azizulzulzaha]

thx!

[@iTouchiPodz001]

What mic are you using? thanks

[@DarrenMiles]

Sony UWP-V1 - high quality wireless microphone!

[@santhosh_shooter]

bro wat lens u4 using for taking video

[@MrJensklein]

Does anyone know if the Sigma 18-35mm has aperture and zoom hard-stops? Also, how does the focal length translates to a Black Magic Cinema Camera? Thank you!

[@JAHistheONE]

Can I use this for street photography?

[@DarrenMiles]

Of course!

[@emadpro]

Is this lens Great for Wedding Photography ... On My cropped body !!!?

[@DarrenMiles]

With it's constant f/1.8 aperture, it would be a great lens for wedding photography.

[@emadpro]

So is it better than canon 24-105 f/4 for wedding .. Srry for many Q .. Thanks

[@DarrenMiles]

Apple vs. Orange. 18-35 better for indoors - low light - 24-105 - better for outdoors and well lit situations, f/4.0 - even with the great high ISO capabilities of the newest bodies isn't fast enough to capture moving subjects indoors, even slowly moving subjects...

[@therandiked]

Sharpness great, but when the light is funny this lens miss focus ...do you really want to lose a shot at a wedding

[@JishinimaTidehoshi]

Fukushima, hmmm, there's something in the water all right... Looks like a great lens, me wants!
