Tamron 17-70mm f/2.8 tested by Opticallimits: “impressed by the optical performance, the build quality isn’t on the same level”
Tamron 17-70mm E at BHphoto, Adorama, Focuscamera, Calumet Germany and Wex UK.
Opticallimits reviewed the Tamron 17-70mm f/2.8 E lens and concluded:
The Tamron 17-70mm f/2.8 Di III-A VC RXD is a bit like Jekyll and Hyde – it’s a curious mixture of good and bad things making your purchasing decision a bit more interesting than usual. On the positive side, there is, of course, the very high resolution, and that’s straight from f/2.8. It is easily comparable to the best in class in this respect. 70mm may lack a little bit of contrast at f/2.8, though. Image distortions are quite normal for a modern zoom lens for mirrorless cameras – they are quite high at the extreme ends of the range without being excessive (unlike on the Sony E 16-55mm f/2.8 G at 16mm which is almost a fish-eye). Auto-correction will, of course, take care of fixing this. The amount of vignetting is very obvious in RAW files at 17mm f/2.8 and 70mm f/2.8, but, once again, auto-correction is giving a helping hand for this. The same goes for lateral CAs, which are slightly higher than average. The lens has been criticized for the quality of its bokeh, and we can see where this is coming from. Out-of-focus highlights are roughly rendered – but this isn’t unheard of among standard zoom lenses. The bokeh in the focus transition zone is actually quite decent. You may spot the occasional colored ghosting when shooting into extreme light sources, but in more conventional scenes, you should be good.
While we are quite impressed by the optical performance (after auto-correction), the build quality isn’t on the same level. This certainly “feels” like a consumer lens rather than targeting professional users. The plastic used for the lens body is a bit on the cheap side. Our sample also exhibited zoom creeping despite having a fairly lightweight inner lens tube. Tamron also omitted the usual switches for AF and image stabilizer, which is something you’d normally expect in a mid-level offering. The high AF speed and the efficient image stabilizer are on the plus side again.
If your only desire is high image quality, the Tamron 17-70mm f/2.8 Di III-A VC RXD is probably a winner. If you enjoy having tank-like build quality, you should look elsewhere, though.
Marc Galers and Miguel Quiles Sony Lens Wishlist 2023: the ‘missing’ lenses in their lens lineup
In the video on top video Mark outlines the lenses that he hopes Sony will release in the months/ years to come. These effectively what Mark thinks are the ‘missing’ lenses from Sony’s current lens lineup, as of April 2023. In the video below you will hear Miguel Quiles wishlist:

Answering some Sony’s new dual layer sensor tech questions: Really as good as Full Frame? Will the same tech be used on future Alpha cameras?
The launch of the new dual layer sensor inside the Sony Xperia 1V (preorders at Amazon and BHphoto) was accompanied by some big claims from Sony. Like: “noise and dynamic range that is equivalent to a full-frame camera“. I have looked on the web to see if someone made a real test on this and I found nothing.
The only comparison video I found was made by DCfever. Here they compared the Samsung S23 Ultra performance with the new Xperia and the Sony is clearly ahead:
And this is Jason Vong statement on Twitter:
I am sure the Xperia 1V has the best camera on any smartphone today! And it’s good to know Sony is always ahead of the game. But I really find it nearly impossible from that the Xperia 1V can match the performance of my Sony A7rV. I believe there is some good marketing “wording” with lot’s of “asterisk” on this statement :)
