I started out with a 24-70 F2.8 and it was too heavy. So I switched to dueling primes, a 35mm and a 85mm both F1.8 so I can shoot in really dark places like subways which is something I do a lot. And I love this setup, its fast to switch and its only 2 lenses. But sometimes I just want to go wider. But F4 is too dark and lacks good DOF, so the 20-40 Tamron fits perfectly replace my 35mm. I can still shoot 35mm all I want but when I want to go wider, its so easy. 40mm on the upper range is pretty close to 50mm which is nice. I will never need any focal length between 40 and my 85 so it works perfectly.
F2.8 is a big deal. For more boke and better low light. Actually the main reason I use mirrorless camera instead of phone is because of bokeh and better low light so Why should I spend on a F4 lens. I think the best option is 24_70 Gmii but it's pretty expensive and also sigma 24_70 which is pretty big and heavy. hard choice
Yes! I got the Tamron for low light. Great for night city shots. It will capture moving video screens crystal clear at night with a blurry background without a tripod. Love the Tamron.
This guy gets it.
I rarely need the 20-40 but it pairs nicely with the 35-150 so that is what I bought. My starting point was the 35-150 and I often need f/2.8, so the Tamron works for me. Great to have all of these options, and I may get more Sony lenses if I pass the Tamrons off to my nephew some day. Until then, I'm happy.
the difference in active steadyshot was much larger than I thought it would be, this saddens me.
Me to - but paying that kind of money for a F4 zoom just doesn't make sense to me. I still think F2.8 is more useful to me as I shoot indoor events.
I am using the Tamron 20-40/2.8 on the 7RIII and can crop easily to 60/4.2 and combine it with the 70-180/2.8 on the A7IV. Very vertasile set up.
60/4.2?
60/2.8
When you Crop you have to multiple the apature by the same amount you did with the focal lengh. So on 40mm F2.8 you will get the look of a 60mm F4.2 @@SuperDraupnir
Than you for your honest opinion on active stabilization with 3rd party lenses. This is the reason why I returned tamron 20-40. For handheld video sony lenses are just in another ligue. Maybe this is the reason why some people are complaining on Sony stabilization. It is good. But not with sigma or tamron.
Yeh it’s definitely better with Sony glass, makes sense though when it’s all the same eco system
I had no idea that active stab is better on sony lenses. That makes sense then why no matter how careful I am with handheld on my a7iv it still looks super jerky with my tamron lenses. Time to upgrade to a Sony I guess.
with active stabilisation turned on the tamron will not be stabilised as its a third party lens, but you can set the stabilisation manually in camera which for me works perfectly
@@danthorne1883does it apply to tamron/sigma zoom lenses ? I mean if you set the focal lengh manually eg. 24 and keep 24 on zoom lens, this will perform in active stab mode as with native sony lens ?
Huh, in my experience I always thought my Sigma 28-70 didn't work very well with active stabilization, but I just thought that was because it was at 28mm. Didn't realize it was a third party lens thing!
Glad more people are talking about the Active Stabilization difference between Sony and 3rd party lenses. It’s a big deal for many situations.
What the heck. Why is this?
@@USGrant21st Yes. that is correct. For photo - its no issue.
I'm just watching ,Chris because I already have bought the Tamron. Nice to see that I am not missing out on IQ according to your tests. The Tamron is perfect for my need to have a small, light, fast lens that makes a perfect companion for Tamron's 28-200 on the a7C for travelling and uses the same 67mm filters. Btw , Tamron lenses may seem plain but they are built like a tank and look as good as new years later. I have already used the USB port on the Tamron 20-40 f2.8 to do some customization; it's a great feature. Curiously, I have never used an AF/MF switch on any of my Sony lenses because I have that feature programmed to the center button on all my camera bodies for consistency and ease of use. The price difference in Canada is substantial between these lenses which ,of course is another deciding factor.. There is quite a difference in the sizes of these two lenses which was also a determinant for me. Good video!
thanks for watching and the ongoing support here!
also since the a7c does not have active steadyshot, the biggest downside of the lens does not even apply to you! cheers!
I had no idea that active stabilisation works better with sony. Is it just with the new sony lens? Or all sony lens?
all
Can we get a 20-50mm F2.8? That would be sweet. Thanks for the video Chris!
hahah we can.. $5k and 15lbs of weight ;)
@@chrisbrockhurst Nah man. It’s only 10 more mm than the Tamron 20-40.
not coming since they have a 24-50 2.8 now
Great comparison, I'm loving my Sony 20-70 so far for outdoor adventure videos (I've used it for one video so far) and it was GREAT. I was using my 24-70mm f/2.8 GM II before that and its a HUGE difference in weight from that lens. Might be my favorite lens at this point.
this is what i mean by when people try out the 20-70 they will be pretty impressed. Such a huge weight difference
@chrisbrockhurst ahhhh man help me out.
I cant decide which to buy.
I have 35gm 1.4 and sigma 85 1.4
I'm going traveling for 6 months and don't want to take 3 lenses.
I'm taking the 85 sigma as it's the boss!
The 35gm must stay at home.
Sooo.. I have a7iv. I want something that is light which they both are. I want a nice zoom. I know the sony and its steady shot will be great. At 20mm the sony is wider than tamron, but the tamron is half the price and could still do the job. I mainly want it for wide photos of machu Pichu etc..
I hope to do abit of video too
@@elzycollins Why don1t you get something like the Sigma 14-24mm F2,8 DG DN or 16-28mm F2,8 DG DN Tamron 17-28? You got your wide angle and they are good for video as well. Would be killer with your 85mm lens.
Very interesting observation about the stabilization of Sony lenses against the third-party glass
I wonder if doing post stabilization in Catalyst browse will show any differences.
same question with Catalyst browse :D
It's not as good. It crops a lot in the frame
@@andora9695 catalyst? you can adjust the crop
The Sony ZV-E1 supports Clear Image Zoom in video which essentially makes the Tamron a 20-60mm. The ZV-E1 is also the first camera to allow AI focus/eye af while using Clear Image Zoom. I fantastic combo if you ask me!
So will the active stabilization still be this bad on the ZVE1 using this lens?
would be interesting to see a crop from the tamron to 70mm to see if its useable. Furthermore the 20mm on the sony look wider becuase its not corrected at all and I really could see it on the vertical lines and as meantioned in the video with the vignetting. I think that for the price the tamron offers actually more. 50mm would be superb but I think its a nice lens
@@USGrant21st ok that's interesting, thanks! If the Tamron would be longer I probably would go for it, the Sony is to expensive in my opinion.
I really like to get the Sony 20-70mm even though I already own the Tamron 20-40, but after seeing the price here in the Philippines, I think I'm going to wait a couple of months and see if the price goes down 😜 Great comparison Chris!
Appreciate you 🙏🏼
Great video Chris! What’s your opinion on Sony 20mm f1.8? I have one and thinking of changing to Tamron 20-40 f2.8 for the versatility. Do you think i will miss out on the f1.8?
Nice and i interesting review. But at the long end? At 40mm I think the Tamron Is a lot worse, what do you think about?
To the photo nut, everything said is easy to understand. For the novice, they have no idea what is going on and are happy to get a good picture. Overall, it seems the Tamron is a great short zoom lens with 2.8 aperture. The Sony looks great and more suited for outdoor use where the 4.0 aperture will not be a problem. I'm happy with the 24-105 4.0 with OSS. On the A7R3, it's a pair made in heaven, very pinpoint sharp.
I've always had this thought that it isn't 100% fair to compare focus performance of a f2.8 lens to an f4 lens because the depth of field is more shallow. Just a thought. Maybe it would work just as well at f4?
I think the Sony also is parfocal and a "sort of" macro capability. Added if you use Clear Image Zoom or Crop Mode; you can extend the reach - really great on the a7rv... perfect timing of video. I had narrowed down to this lens for my trip to Japan. I think it'll be a great hybrid lens for travel. (I was looking at the 24-105 OSS originally). * I wish this had OSS like the old Zeiss. ** In my dream, a 20-50 1.8 would be sweet!
Why "don't buy one on these'?
Because clickbite
Great job on the video Chris! Thanks for making it.
Anyone know why the active stabilisation is so much better with Sony lenses? What’s going on electronically?
Im guessing gyroscope data
How would you set autofocus on the Tamron without the switch ?
(Sorry, I'm a new photographer.)
You can set in in your camera.
I’m just a sucker for faster lenses, but agree that 20-70 is just more useful on all levels.
we are all trained to think that way haha
Variable aperture glass solves the size/cost/weight equation. They just need to make the lower end f2.8 (or lower) instead of f3.5 or f4. I'd actually like one that was faster on the long end for smaller DOF (if that is even possible.) Nikon made the 16-80DXVR which was a stellar all-around lens, other than being prone to "inhaling" dust.
Great video Chris. I like the Sony's range and the extra reach on the long end. The extra cost is not as much of a concern as I consider lenses as long term investments and all thing being equal, $1,100 is not that bad.
I shoot mostly landscapes and the fact that Tamron is sharper in the corners at 20mm is a major plus. How is the sharpness in the corners at other focal settings, say at 50mm and at 70 for the Sony and 40mm for the Tamron? Thanks.
thanks for watching Boris, I didn’t comprehensively test it at all focal lengths but there are some more specific tests out there. Gerald has a great vid on the Tamron 20-40
@@chrisbrockhurst Thanks Chris. I'll look up Gerald and a few others to get a better idea. I like your review as it is a practical real life test not just charts and brick walls!!
I think it's clear as day that the images are sharper on the 20-40mm f/2.8. Thank you for this video which is what I was looking to figure out before I make my purchase.
Great video! Chris pls tell me, do I understand correctly. Sony 20-70 does not have Ibis, but as far as I can understand, Sony IBIS works better with native lenses even if they do not have in lens stabilisation?
Yeh when we talk about IBIS now it’s gunna be in body. New Lenses don’t generally have it anymore unless they are tele zoom. The in body stabilization is called ‘active stabilization’ and it will 100% perform better with sony glass than any 3rd party. (At least with newer sony lenses anyway)
@@chrisbrockhurst I have the older 24mm 1.4 GM and it’s a big difference in active stabilization as well.
Thanks Chris I was going to buy the 20 40 Tamron with a A7R5, but this video has me thinking, am I making the right decision. I think I am because I do shoot indoor events a lot, just not sure if F4 is enough.
yeh tough decision, either way both are great lenses in their own respects.
And now there’s the Tamron 17-50mm f/4!
Yep, gonna cop this one in place of the 17-28
I don’t think I am buying lenses anymore other than Sony lenses…I like my Tamrons but now Sony is really pushing some of these features that are not available on 3rd Party lenses. My next lens will probably be the mysterious 16-35mm GM ii (that will replace my 17-28). Then I need to get the new 24-70 to replace my Tamron 28-75. I need to go make more money lol 😂
yeh the sony features are really making it hard to not pick them these days
I feel the same way. I am staying with Sony native.
I love my G’s and GM’s especially for pro work.
Mate I tried to understand the difference on the blur. I couldn't. I think more and more people will understand soon that they don't need 2.8 on a full frame camera that much.
I would argue that when you need f2.8, f1.2 would be that much better. I've been shooting APS-C for over 10 years with f2.8 lenses, and F4 on full-frame cameras is better, so there is some truth to what you're mentioning. However, we need more affordable 1.x lenses with the camera's brand. I really like the 15f1.4G, but they haven't released a camera for it. The A6600 has USB-B, and that is a deal breaker for me these days, and I need an EVF. ;)
So which one are you keeping!?
The 20-40 is a much better indoor event lens, especially paired with a 35-150. I plan to replace my 17-28 with one soon.
I need wider hence 16-35 CZ and 24-105 work admirably for me
I tested this with samyang 18mm and the active stab made a visible improvement over standard stab.
video on my channel
Your review from a user POV is always more useful than a Techy graphs & specs review. And you covered a lot of usability scope here. I was happy to see your surprise at the Tamron sharpness and lack of vignetting since I have purchased the Tamron- in fact, you were making me nervous up until that point. 🤔🤣 I was reserving my "out/but" in case I needed it since I mostly shoot indoors with it and don't need the Sony extra 41-70mm. Bottom line for me is I saved a lot of $$ and have a very workable AF eye focus lens. If I was a respected pro, ahem, like Chris B, yeah, I'd do the Sony. 🤣
Its a good purchase - Im hoping to buy the A7R5 so the 40mm will be a 60mm at 27mp.
I would buy Sony but then again I don't need any lenses right now. That said my favorite lens is my Tamron 35-150 it rarely comes off the A74. I got a sweet deal with the 35-150 and the 150-500 about a year ago and I'm happy. I had the 16-35 Sony GM and I ended up with the Tamron 28-75 in a deal and I have yet to use it but will be selling it with my FX3 when my FX6 get here. My next camera will be the Sony FR7 Cinema Line PTZ Camera which I think is amazing.
I will never park my car anywhere near downtown SF ever again.
I'm just watching... So you're welcome haha but honestly, leaning more towards the Tampon, but only because I already have the 28-75 and the 20-40 just seems like a nice little travel lens for vlogging
That’ll slide nicely in with the other tamrons 😉
Trying to get an x100v to travel with so I don’t have to worry about what lens to use.
the worlds rarest camera right now
@@chrisbrockhurst I actually broke down and bought a used x100F which I’m really enjoying. I do have a Sony a7iv with several lenses including the “beast” 35-150 (which I love).
Seems you don't see the dimensionality of one lens over the other? it is pretty obvious, the one on the left has a better dimensionality.
Are u testing different mic at the same time ?
LOl
Don't forget, every exemplar is different 😉
considering that in europe the sony is literally double the price, the tamron is looking pretty strong.
“20mm - 70mm is more useful.” Very insightful. .
IQ comparison at the long end for the Tamron?
Unfortunately this is also the weakest range for the Sony
im just watching cause I can't afford either 🙂🙂
All in good time!
I’d keep my 20-40 over the Sony any day of the week.
You've made a good case to not buy the Tamron here....
well the Tamron offers a huge amount of value if the budget doesnt allow for it
I believe the 24-105 F4 OSS is better than both
Sony's software limitations are joke
Sony is 400$ more ….sooooo
8:18 I'm sorry but the f2,8 aperture is more important than 70mm on the long end of the Sony. You can get that 70mm no problem with a relatively small crop. I'm pretty sure that if you really need tele than you just get a tele and you don't care about the long end.
6:10 looks like the Sony has a bit of lower light transmission and that is why it looks as if it has a bit of more contrast.
I got the Tamron 20-40mm and to be honest that is the perfect gimbal lens imo. I'm using it with DJI RS3 and it doesn't matter for the balance if you zoom in and out it's always balanced. I might even sell my GM 35mm because I did a test and side by side there is really no difference at all. There is no possible to say that one is EUR-1,600 and the other EUR-800. In terms of sharpness side by side the GM wins by a slight margin and the GM is a prime top of the line lol
I was really confused about who the Tammy was for, but then I did a couple of video shoots and went “aha!” Now I too own one of the Tamron’s specifically for gimbal use.
@@angelamaloney4871 Yeah and for gimbals dials and buttons on the lens isn't really that important IMO. Now I attached the focus motor of the RS3 to the Tamron 20-40mm and it works great. Even though it is not "parfocal" I would I argue that this doesn't matter at all 98% of the time.
7:12 that is not vignette there is just no more lens on the Sony lol
