Tamron 20-40mm f/2.8 DI III Reviews

Works great with AF on Sony A7IV

By Jerol
Rated 5 out of 5
Date: 2022-12-02

I chose the 20-40mm Tamron lens as the full-frame next step up to be a companion to my current 11-20mm APS-C Tamron on my Sony a7IV for in-studio talking-head videos. With my range of 11-40mm now I have all the wide-angles covered. It is quite fast with the Sony AF, matches my current 67mm diam lens, and the light weight makes mounting variations easy. It was a good buying decision.

Quick evaluation

I typically shoot with a super telephoto, but got this lens to accommodate those times when I want to capture a stunning vista and my 100-400mm just won't cut it. WIth that said, I've used this very little as of yet but I'm very happy with the results so far and will continue to evaluate its capabilities in the near future. This lens has a short zoom span, but just enough to feel and perform like a prime which is what I want. Prior to buy it, I expected that my new smart phone would serve as a good stand-in for a wide angle, but the phone hasn't lived up to the hype and therefore my need for a real wide angle.

Awesome on my Sony A7IV

I'm using this lens for photo and video and I'm blown away with the IQ. Ended up selling my used Tamron 17-28 for this and have not looked back! The VXD linear motors fast and quiet for video and eye tracking works flawlessly for video and photos. I now have the dynamic duo of the mighty 35-150 F2-2.8 and now this! Buy one now, they don't stay in stock for long!

Excellent walk around lens for place like Las Vegas

By Nick
Rated 5 out of 5
Date: 2022-11-21

If you are looking at performance charts and stuffs. This is not a perfect lens however at $700, you can beat this lens. For most walk around situation, this lens is very sharp. Crowded places like Las Vegas Bellagio, this len is really shine. I know people complain about it does not reach further however there would be compromises for anything. In the perfect world, would you want a 16-200 lens? However there are no practical reasons for such lens and it would massive. If you want a walk around lens, go for it.

Excellent, but not perfect, walkaround lens

By Jeffrey
Rated 4 out of 5

I preordered this lens as soon as it was listed because IMO it's a near perfect focal range for a walkaround lens (would've been even better if it went to 50mm, but now I see why they didn't). The price, size/weight, and f/2.8 aperture made it almost a no-brainer, especially paired with my 70-180 f/2.8 as a lightweight do almost everything kit. After a few weeks with it, here are my observations: Size and build: This is very compact for a full frame f/2.8 zoom. It's slightly smaller than the Sony 24mm f/1.4 GM, but bigger than the Sony 20mm f/1.8 G. The 67mm filter thread is great because it can share filters with so many E-mount lenses, both Tamron and Sony. It's all plastic, but I know from experience that paper-thin aluminum doesn't provide any more protection than good quality plastic, so it's fine by me. I did notice when I first put it on that there was quite a bit of resistance trying to lock the bayonet, which I assume was due to the weather sealing gasket. It loosened up a bit after several mounting cycles. Sharpness: Center sharpness is excellent right from f/2.8 at all focal lengths, nothing to worry about there. As for the corners, I can tell it was optimized for performance at the wide end at the expense of the long end. At 20mm, the corners are very good right from f/2.8, and by f/5.6 they are excellent, almost as good as the center. At 20mm I have no reservations about using it at any aperture anywhere in the frame. However, at 40mm and f/2.8 the corners are well... not good (which is why I see why they didn't push it to 50mm). I was going to say they are straight up bad, but I suspect there is some issue with field curvature when focused at or near infinity in the center. They improved a bit if I focused in the corners, though still not great. It takes until about f/8 for the corners to get to what I would call very good. Flare: Flare resistance is pretty good. It's there if the sun is in the frame, but it's generally pretty low contrast, so you're often not going to even notice it unless it's on top of a very dark background. Below f/5.6 it's almost invisible, and gradually gets more prominent the more you step down. Aberrations: There is some chromatic aberration and distortion, but that's very easily fixed in post (especially with Lightroom profiles) so nothing to worry about. There is a fair bit of vignetting, even stopped down, but that's about par for the course for fast, wide, full frame zooms. If you want to try to use it for astrophotography, the coma seems pretty low, definitely above average performance there. Starbursts (a.k.a. sunstars): In an age where it seem every lens gets rounded aperture blades (seriously, who cares about round bokeh at wide angles?) that create blurry, messy starbursts, I was pleasantly surprised with this lens. Since switching from Pentax APS-C a long time ago, I've longed for a lens that could produce starbursts as easily as the legendary SMC DA 15mm Limited (not the later HD version that added rounded blades). This lens doesn't quite reach the heights of that monster, but definitely well above most other lenses. You already get decent ones at f/8, and they get really prominent at f/11. By f/16 diffraction starts to diverge the points, so f/11 is the peak IMO. Conclusion: Given the full frame range of moderate ultra-wide to normal, the f/2.8 constant aperture, the very compact size and weight, and the fantastic image quality at 20mm, all for just $700, this a highly recommended lens. However, the problematic corners at 40mm really aren't something that can be just ignored, so I can't give it a perfect score. I'd give it a 4.5/5 if I could.

Perfect for documenting family

This lens hasn't left my camera since receiving it. It's small and light enough that I can now take my camera everywhere. This focal length is the sweet spot for capturing family memories in just about every situation. It's wonderfully sharp, with super reliable autofocus and great neutral colors. Honestly, I couldn't be happier with this purchase.

The perfect Gimbal Lens for Wedding Work

By Miguel
Rated 5 out of 5
Date: 2022-11-29

In my opinion this is the perfect lens for my Sony FX3 camera for wedding gimbal work. I was never a fan of the 16mm look so having 20 to 40mm is a game changer for me. Quality of this lens is good. If you are looking for a lens with some kind of character or look this is not the lens for you. The image is simple. AF is good enough for my work and the weight of the lens is perfect. Again for my kind of work I think this lens is perfect.
