[@Scooter-K]

LOVE IT! did a shoot this morning on my A7III. Fair to say, "I'm in love with this lens."

[@charleschien6949]

Interesting video. Thanks for sharing. Would you do the same video with Sony GM on A7III and Tamron on A7RIII? I wonder if the focus speed of the GM is affected by the different number of focusing "cells" on A7RIII vs A7III.

[@kasekuchenmitsahne9568]

Why don‘t you just switch cameras so that you can test whether the af is worse because of the camera?

[@treepizzle]

Käsekuchen mit Sahne I thought the same thing. Probably because he didn’t think it would be this big of a difference. You can tell he was doing this solo with a tripod. I’m sure he’ll do that next time? Maybe?

[@geirisk8]

Because with two cameras you have the subject identical on both shots.

[@KedarBhatlive]

Exactly what i am wondering

[@MrKockabilly]

Exactly. The camera sensor (thru its focus points) is the one that knows whether a scene is in focus or not... and correspondingly gives command to the lens.

[@ericohenrique4728]

I think the a7iii have a af improvement better than a7rIII because of it, the tanrom have similar result than native sony lens

[@lyonngo]

Sweet test Jason! What you can do next time is switch the lenses on the bodies halfway through-this could help let us know if the body affected AF performance.

[@JasonVong]

Good idea!

[@swonghobby]

Hey Jason, when you got time. Do a straight photo comparison of the Tamron 28/70 vs Song GM 24/70. Just photos. Sharpness, Vignette, etc

[@jamesjung3137]

That's what I also want to see. Thanks

[@WuschelofDespair]

I feel like this is such an important lens for the Sony system. Reasonably priced and it seems to be extremely good. Hope this gets the industry moving. Excited to see Sigmas real native Art lenses, not just the Canon with integrated adapter. So big, heavy and clunky for a mirrorless I think

[@Scooter-K]

Just received my copy of the Tamron, its the one lens I can honestly say is simply amazing and competes with Sony for sharpness, and Zeiss for color rendition. Simply awesome

[@Nick-rh8qk]

maybe it is easier to switch the lenses around so i get an idea of how fast does the GM focus on A7III.

[@JasonVong]

Next time! Just wanted to do a quick video yesterday !

[@Nick-rh8qk]

anyway if you come to NZ please let me know

[@IMDABROWN]

Jason Vong what a cop-out answer, you could have did 4 mins with the lens flopped and took back 4 mins of the other test

[@RickThatcher]

Do it yourself if you don't like it. You can make a request without being a dick.

[@ankurchitkara383]

Hi Jason. as usual, an informative and entertaining video. At 70mm I thought the gm had more magnification as compared to the Tamron. Can you please confirm. Thanks.

[@casualbricks]

Was waiting for your Autofocus test. This just sold me on the lense. Thanks!!!!

[@JasonVong]

Glad this helped!!

[@DevanRawn]

Do you think the Tamron is exposed slightly brighter because that lens has a lower T-stop at F2.8 than the GM? or is it just my eyes playing tricks on me?

[@JasonVong]

Maybe! Even though the settings were all the same, the metering showed it was a bit brighter! Good eye!

[@samyrnovelli]

Is not it the camera that is influencing? A7R III have more/little pixels = less light? I can be talking bullshit haha

[@zakcovert3142]

Thanks man. After further evaluation, I’m going to get this Tamron lens for the versatility and be my daily lens that generally stays on the camera body.

Hi, is eye AF only in 1080p? Not in 4k video mode?

[@JasonVong]

Eye AF only works in Photo mode

Jason Vong thankx 📷😊

[@oriomenoni7651]

Based on what I can see in your test, the Tamron is faster in acquiring the subject when starting from zero (i.e. when the subject appears out of nowhere), but the GM is definitely better in keeping track of the face when the subject is moving. It keeps the face engaged most of the times, whereas the Tamron seems to miss the face easily and to take quite some time in re-engaging it. So based on what I can see my opinion is not very good about the Tamron. For me when shooting video a good tracking ability is more important than the speed of initial acquisition.

[@shekusheriff1438]

What the difference in price of the two lenses?

[@dresistena3178]

Tamron Lens is gonna be about 800 whereas the Sony GM Lens will be 2000-2200

[@DennisMoncla]

When is fast and responsive I thought the Tamron was better than the GM but they were on two different cameras with different focus systems. The focus on the 73 is slightly better than the R3.

[@immfocus]

Do you think in an 7R II would be much worse?

[@subirthapa8542]

Maybe also do a Sharpness , Colors comparison of two Lens on A7r3

[@v3zMedia]

Welp! There goes the G Master sales. Tamron is now in my cart. 😂

[@heyitzLou]

v3z See you in August when your backordered lens finally arrives.

[@v3zMedia]

I can get it locally at ProCam too. So no August for me. Lol!

[@heyitzLou]

v3z ugh. Mine is still backordered at B&H.

[@v3zMedia]

I heard they were backordered the 1st week it was announced. Sigma just released the Bokeh Master info today. $1,600 end of June.

[@youdontknowmeman01]

don't base your purchase decision on this video if AF is your concern. the a7iii has a9 levels of AF, and the a7riii only half that

[@CYKuo-yl9lg]

Waiting for 2875’s image quality review in photography aspect!

[@ArunBarnard]

Wow didn't expect such good results from this lens! Would be nice to see a follow up with the lens on the same camera, but I'm pretty much sold. Hopefully people can stop complaining about uber-expensive lenses for Sony now.

[@aidangreen1491]

Please do a sharpness and noise test! If the results of the Tamron are anything similar to the G-Master, I'm switching.

[@Laajaaairsoft]

5:51 Tamron Missfocus Sony full time in focus, on winter i sell my ASPC technique and i buy my first FF and that A9 + 70-200mm G F4 i try shooting motocross, but i had a6400 + Tamron 17-70mm and i have a lot trash.

[@rjog1991]

Always good news seeing these vids in my feed!

[@JasonVong]

Haha 🔥🔥🔥

[@theTechNotice]

Did you have the cameras landscape or portrait orientation ?

[@mariaengstrom4384]

All we really need to know Jason: Will it balance perfectly - and get clearance in the back - on the Crane Plus with a Manfrotto Quick Release?

[@JasonVong]

There's enough clearance. Just checked!

[@mariaengstrom4384]

You're the man Jason, seems like an awesome combo for that gimbal. Just used the C+ on a trip with an RX100V, may have to pull the trigger on these two now. Thanks from Stockholm!

[@user-wh7pu4kl6h]

Could u plz do a 10-18mm video for the Sony A7? Thx and great video for comparison

[@jdinbigd7437]

Thanks Jason. One thing you could do is swap the GM and the Tamron between cameras.

[@JasonVong]

Haha! I may redo if I have time!

[@oscarkhlee]

At 4:40 of 70MM, Jason's face is thinner on Tamron's image than on GM's image. At 5:05 and 5:22, the images show a thinner Jason on left. Maybe it is just the angle. Can anyone advise?

[@rodelmedia6184]

it will be a great pickup for those who were contemplating on not spending on the expensive 24-70GM, but not sure where to get it repaired if something happens to the Tamron for working professionals.

[@rvg1997]

Tamron service for me has been very fast and I have never had to send a lens back because of poor repair service.

Interesting test Jason, thank you for putting in the effort and getting a bit of exercise at the same time. :) They both perform quite well especially with the response set to fast, pretty much a toss up with the slightly different attributes balancing out. The Tamron looks like a the bargain favorite by virtue of it's lower price, it was difficult to see any critical image quality comparisons in this test but they both looked good with the GM rendering slightly warmer.

[@JasonVong]

Thanks Carl!!

[@Brizandeer]

Hmmm this is such a tempting lens!!!! Would this work well with the a6500 you think?

[@JasonVong]

I don't see why not but I will give a shot when I get the chance

[@Apaolino21]

Solid performance! Very excited for this lens.

[@JasonVong]

I was shocked too!

[@krishnastock]

Ordered through your link! If possible please compare to Zeiss 4/24-70! I hope that the next Tammy is a 2.8/70-200 for about the price of their current Canikon G2 version! :)

[@JasonVong]

I probably wont. I've been hearing the 24-70mm f/4 has softness issue. I'd go for the 24-105mm. Or this!

[@treepizzle]

Interesting. I bet you didn’t expect the Tamron to spank the Sony. Now you’ve got to switch the lens and body combo! Verify it wasn’t just he camera system. 👍 thanks for the video.

[@hamzabenarafa6782]

same question here, why not simply switch ?

[@ClevelandTerry]

Good test. Curious why you didn't just swap the lenses on the camera bodies. That would have told you if the tamron is truly pulling focus faster.

[@JasonVong]

Wanted to do a quick video. Will see if I have time to redo

[@ScottsReviews]

To me the first round the g master tracked the subject better as it moved away. Tamron focused quicker as the subject popped into frame.

[@JasonVong]

I noticed that too. Especially when the object is coming forward

[@GeorgeRTurner]

Thank you for putting all the effort to make this very useful video! :-) I'm considering the Tamron lens and your tests really help me...

[@JasonVong]

Glad I can help!

[@zabigraphyphodeoproduction8514]

Thanks Jason! I've been looking around for someone to upload on the new Tamron + AF Tracking. Decision has been made!

[@robzildjian]

Shoulda tried swapping the tamron to the a7r3 and the 24-70 to the a73. Good comparison though.

[@JasonVong]

The focus was on the a7III combo anyway. I was too shocked by it and forgot I shouldve switched! haha

[@danreynoldsphotography2735]

Nice! Why didn't you swap the lenses on the bodies to see if the tamron still focussed faster on the Riii?

[@JasonVong]

mainly wanted to focus on the a7iii and tamron combo since it will be the most popular. if i get the chance, I will redo the test

[@JamesZhan]

I have been waiting for you to get your hands on this lens! Please do a full review of it (photo/video) if you can! I need to know how much tears I should shred for buying the GM version.

[@JasonVong]

Gonna be shooting a wedding this weekend with it

[@weixzero6038]

The focus test might not be fair to the Tamron, because of the constant vehicle moving on the side due to the framing. Quite surprised the Tamron keep up quite nicely, it acquires focus much better when the subject is closer to the camera.

[@JasonVong]

The focus area was set to focus zone center and face detection on so the cars shouldn't affect the AF

[@vpr5562]

Jason, could you please check how the lens behaves at f9, f10 etc? Will be much appreciated.

[@whatdoesnt]

Yes 🙌🏻 pre-ordering now. Thanks for making me spend more money💸

[@JasonVong]

it's my job! hahaha

[@petergrillone2064]

Ive been shooting with this lens for the last 2 days, on actual photoshoots and it has been flawless. I actually listed my GM on ebay after the first day. Sharpness has been truely amazing. Shooting on a A7R3. I compared it to my GM and couldnt justify keeping the GM. The Tamron for my use it a better lens with better autofocus speed and 99% the same sharpness

[@MisterBandsman]

thats great news! I wonder how well this would balance on the crane plus. It would be a killer combo for events, light weight, good autofocus, good range and good price

[@JasonVong]

Just tried it. Haven't looked at the footage yet but it balances fine!!

[@andyyoon7853]

Thanks Jason. Looks like you can save quiet bit of money with a7iii with tamron if your product is more toward to video.

[@lordbilal2012]

The best review of the lens for video so far amazing

[@ReggieU]

Thanks for this test Jason, this was very helpful. Looking forward to getting mine and doing some tests of my own

[@JasonVong]

You're welcome!

[@markcinelast]

hi thank you for the review. was that the tamron rxd?

[@natepalmer5792]

ahhh been waiting on this review. Thanks!

[@JasonVong]

thanks Nate!

[@marcoandreas185]

Great Video👍🏻. Did. you notice any focus noise?

[@JasonVong]

Only if I smush the lens into my ear but other than that, not noticeable in the field

[@HDPhysiques1]

This intersection looks familiar. Culver City?

[@balbonvids7124]

I wonder if this will be good lens for all around traveling- compairing to sony 18-105. Mainly day photography

[@gregzargo9413]

I preordered after watching this but would like to know your honest opinion about image quality when compered to GM going off of this test???

[@alvinlee5884]

Hi Jason, I usually use AF to get initial focus, then toggle to MF. How is the MF control on this lens? Compared to Canon lenses, is it easy to nail focus under MF?

[@kiukle]

To further test is if was the 7 versus R causing slower focus, you should have done the same test and just swapped the lenses on to the opposite bodies. :P

[@markshirley01]

Do you have to register a face for Face Detect or is it just a mode that can be assigned to a FN button.

[@JasonVong]

You don't have to. Face Detect works automatically. But you can register if you wanna track a specific face

[@adamknight309]

Has the lens got image stabilization?

[@LetsGoHelio]

Jason has the body of a Greek God.

[@JasonVong]

LOL I wish!

[@ayaphoto1718]

Hi Jason, the difference in speed of focus is pretty crazy! Could you do a test where you test the focus and then reverse the lenses so we could get a clear picture wether the speed of focus is due to the lens or the added focus points in the a7iii? I'm buying a sony body and so far I was leaning towards the a7Riii but that might change my mind. Thanks!

[@JasonVong]

I have a few more days with the lens but I will be using it to film weddings. If I have time, I will redo the test

[@jinzhou1297]

Hi Jason, if I want to use one lens for travel, tamron 28-75 or sony 24-105?

[@cactustweeter2890]

Jason, I got my B&H shipping notice just a few minutes ago. It hasn't made it to the processing facility yet so I don't know the exact delivery time. I'm hoping for delivery by at least Saturday so I can enjoy it over the long weekend. :-)

[@JasonVong]

Did you do overnight?

[@cactustweeter2890]

Unfortunately no. I blew it in the planning department not noticing that May 24 was so close to the weekend with a holiday on Monday. It looks like I won't get it until Wednesday, May 30. Anticipation... :-)

[@mirageinmirror1497]

Great idea, but please resynchronize vodeohalves! Some parts is a7riii bit before a7iii

[@dallatorretdu]

1 month ago I preordered this lens... I hope I didn't do a stupid move, can you test the fringing and chromatic aberration? It might not compare to a prime lens as far as Bokeh but I would be sure to use it confidently even on outdoor events

[@JasonVong]

i will see what i can do

[@neosinfo38]

Great video! I would like to see this lens on a7ii vs a7iii so we can also see how much better is the focus system on the a7iii compare a7ii. Thanks

[@JasonVong]

No need for test. It's way faster!

[@jeffreyhong6191]

any chance we can see this test on a slightly older camera, like the a7sii?

[@JasonVong]

a7SII does not have PDAF so it's already slow with the AF regardless

[@Roxus3]

Hi! Does the Tamron have any (auto)focusing noise? Thanks

[@nightcoder5k]

Perhaps, the Tamron handles focusing faster because it's on the A7iii? I'd say you need 2 same cameras just to be sure. :)

[@loriphillips7902]

Thanks for doing the comparison. Looks like a winner. I pre ordered the Tamron the first week of may, and it was scheduled to be released yesterday. However, I was informed today that Sony hasn't "allowed the official release yet". 8O I need the lens for a wedding next weekend. Yikes!

[@iancairns01]

I have it on backorder. I can see what people mean about the bokeh. Deffo not as nice

[@andreasi8745]

Hi You have to use the sametype of camera, and your head looks rounder on GM? why distance difference

[@infinitefighterful]

Hi Jason!I have a crave v2,is it strong enough to hold this tamron lens?

[@JasonVong]

on the crane plus it is!

[@TheFirstCause]

I really liked this comparison. Mostly as a demonstration of the a7iii autofocus abilities. I can only imagine the new a7siii whenever it is announced will have similar or better and that is an exciting thought.

[@mpstudio140]

Do you habe an video with video settings for this capture with the a7iii 28-75?

[@whyFINAL]

What is the focus distance from the sensor on cca 50 mm focal lenghth? Thanks

[@elhasasadsa]

I have a sony a7iii with a canon lens 24-70 2.8 from a year 2014 with mc 11 sigma adapter….. and most of my shooting is video if i upgrade one of the lenses tamron or sigma better than canon lens for a sony ? have a big different and quality ?!

[@sebastienbass]

Great comparaison ! I have just a question this tamron is compatible crane plus ?

[@JasonVong]

I am testing that today!!

[@sebastienbass]

Jason Vong ok i wait your test before i but it ... because version GM not compatible and it very expansive

[@photographerjonathan]

I was looking at the image quality maybe more than the focusing, and its hard to see an image quality difference, they seem to both have similar color, contrast and sharpness and background blur, maybe the Tamron even seemed sharper, I love saying that to drive all the people who bought the GM crazy haha, but Jason please do more image quality comparisons with the GM for stills using the A7r lll, I have been telling people that I bet the Tamron lens holds it's own against the GM, and so far it seems like it does, but I just wish that Jason would've run up and down a few more times lol

[@JasonVong]

Also don't forget, the a7III shoots slightly better video quality so that may have been the reason! Just wanted to make this quick video to get it out there that the AF is solid! That's what matters to me! I will do the other test in the next few days but hard with such limited time

[@obayedh]

Really!? I have found the G-Master is significantly sharper, much better bokeh and color rendering is way better than the Tamron. I know the Tamron is way cheaper and may be a bit faster, but then a7III is a better focusing camera too! Tamron is a good option for the beginners for sure IMHO :)

[@photographerjonathan]

you found all that out by watching this video ?

[@PKmode]

There are several reviews out now. JV is not the only person who has a copy.

[@ReneGamper]

Is it just me or does the Tamron have less background blur on 28mm?

[@WalterSmolenski]

Jason. Thanks for the review I am looking forward to getting this lens my self. However with this video you have added some fuel to the fire for those that keep saying that the autofocus of the A7III is so much better than the A7RIII. I am not sure if this is true just based on the number of autofocus points. It is a topic that should be addressed for sports shooters but very difficult to do a reasonable test.

[@JasonVong]

They did say the a7III has the same AF system as the a9 so I wouldn't doubt it. But with the work that I do, they felt the same. If I done sports, that might be a different story!

[@WalterSmolenski]

Yes it makes more sence taking the 24mp autofocus system of the A9 and using it in a 24mp camera than to use a 42mp system in a 24mp camera. But that does not address real world differences of the A7III vs the RIII autofocus speed. Other camera factors like CPU etc will have effects, and the A7III is not a A9 for processor speed. Sorry, but I just get annoyed from forums where people actually think the reason all their pictures of the kids running in the backyard are out of focus is because they bought a camera without the best autofocus system.

[@rvg1997]

Jason, I enjoy your blog but I think you may have gotten your test wrong. After watching the video several times I think by having more of the building in the A7R3 and 24-70 it seems to focus on the building and then has to switch back to you. Where as the A73 and 28-75 just has to focus on you on the sidewalk. Love your videos but I think you need to do a retest using you as the main subject. I have the A7R3 and use the Sony 28-75 f2.8 on it with great results.

[@JasonVong]

I will see what I can do!

[@sayyar9]

Hi Jason... Tamron or New sony 24-105? Because I'm little confused in between those lenses I already placed an order but it can be cancel any time.. Should I proceed with TAMRON Backorder order? or shall I get sony 24-105 or Zeiss 24-70? (Budget only for one =)...)

[@petergrillone2064]

Ive never owned the 24-70 f4, but I have owned the 24-105 and the 24-105 is a great lens, just not as sharp as the Tamron. Even if the sharpness were the same, the 2.8 gives me much more to work with when it comes to HSS

[@ApertureViews]

My Tamron 28-75 hunts in low light but when I turn up the iso it’s finds focus just fine! Just bought it so it already came with the updated firmware.. just want to know if the hunting is normal in low light situations?

[@ShantulNigam]

Did you try it again with the patch?

[@johnbato657]

Always great videos!!!!

[@princeair]

Hey Jason, why not swap the lenses on each camera and compare?

[@JasonVong]

too shocked from how good the Tamron kept up that I forgot 😉

[@princeair]

I don't blame you, I'm just as shocked by how fast it was pulling focus! Very impressive

[@edkwon]

The a7iii + Tamron combo definitely kills the Riii + GM combo for AF lockon speed

[@NiazMahmood1977]

I would to see Sony A7iii auto focus performance with Canon EF 70-200 f2.8 with mc-11 adapter both in portrait and landscape orientation in low light.

[@ErethilClaw]

Just for the show you deserve the thumbs up xd, how is the eye detection in low light conditions?

[@ghostpanic]

I don't understand, In the 1st test the A7III shows a lot of moire' of your grey T-Shirt, Yet the A7R III shows none. But doesn't the A7R III have no AA filter. But the A7III does have one which is supposed to be there to reduced moire'?

[@ccphotofilm]

Hello Jason, what about autofocus motor noise and hunting?, I see a huge $ difference and I am fan of saving money, great review!

[@JasonVong]

only if you press it to your ear, but other than that, not noticeable in the field

[@gsonbiswas9765]

Finally it's on your hand. Please compare these two on the basis of bokeh, distortion and colour rendition.

[@JasonVong]

bokeh aint too shabby on the Tamron!

[@cherifshawky4846]

Great video Jason.Would like to see a similar comparison with two A7 mark3.The tamron seems to be holding it's own very well, looked sharper at 2.8 on the first auto focus mode.When you switched the af settings the Gmaster looked sharper but the Tamron held up really well.I would still like to see a comparison with the same body's but overall Tamron looks like they did a great job with this lens.

[@JasonVong]

Also don't forget the a7III shoots 6K full pixel read out so the 4K video looks slightly better!

[@cherifshawky4846]

I'M more of a stills shooter so I have to get up to speed with the video, but im really excited about this lens.I liked using my Canon 28-70 over a 24-70 so it would be nice to have one back in my kit again.Keep up the good work, really enjoying your vids.

[@damidammi]

Didn’t they always say that the a7iii doesn’t have track autofocus for video? 🤔 I’m confused

[@petercerrato8447]

Hi Jason... Just got this lens yesterday, but the Autofocus works zero percent of the time on my A7iii. It’s always out of focus. What firmware are you running on the lens?

[@JasonVong]

dismount and remount the lens. I'm having the same issue. so is Ryan Kao and that1cameraguy. I will talk about this in the next video

[@petercerrato8447]

Jason Vong That makes me happy and sad 😆... Dismount it while the camera is on?

[@cactustweeter2890]

Jason, since I have a7r iii I would like to see the comparison on 2 a7r iii's. :-)

[@JasonVong]

That! is actually possible! a couple of my friends have the a7riii

[@HI30s]

It’s so weird how all Sony lenses produces a “cold” feel. I believe the less post processing the better, just so I can go out and shoot more. It seems Sigma, Zeiss, and Tamron produces a warmer feel for skin tones. Am I wrong?

[@JasonVong]

I didn't test for that so I can't say for sure. :(

[@i_am_kayode]

Tamron is the clear winner here

[@marcoblondus3204]

review on the image quality?

[@sendykumalakanta1]

Luv the hamster face while you are running 😁

[@JasonVong]

my only workout of the year
