Yes, F2.0 in your images is really nice (at least starting from 1 meter). I assume these are center crops at 24 MP. I looked at them in 100% view, pixel peeping at 140 ppi. Would give a print with ...

If you have done careful focussing on the image center, ruling out any AF errors, I would clearly say that this lens is decentered.

Given the field of view, I guess that your image is not a 1:1 crop but the full image scaled down to ca. 12 MP. If my assumption is true, this looks pretty bad (if you can exclude factors like ...

I think so as well. Hope to use this lens many years to come with the FTZ adapter and still on DSLRs.

I don't think that the image quality between the Sigma and Tamron is very different. For me, there were four reasons why I chose the Tamron: (1) weather sealing (2) tripod clamp available ...

I can only comment on the Tamron 100-400. It shows really nice resolution even wide open in the center over the whole zoom range, even at the tele end (used on D7500, being a pixel peeper). ...

I have it in Nikon mount and use it on DSLR and Z with FTZ adapter. In both cases, the AF is just fine, at least for static subjects. I have not many moving targets. ;-) I had to dial in AF ...

Really great photo, one can imagine a lot of different stories about the "lady in red".
I also wondered how it would look like in a non-diagonal composition, but you are right, verybiglebowski,...

@RCicala: Thank you for the clear explanation. Very well understandable that this is too expensive. I have recently done a casual test of two Tamron SP 35/1.4, following your "plane field of grass"...

I am surprised that this review did not get more responses. Anyhow: Very nice review with useful sample pictures, thank you! And the lens itself is really great, btw.

Me too.

I also stumbled about this wording. Complete marketing nonsense... Nikon's "nano coating" sounds very reasonable in comparison.

Meanwhile I have also found the answer to my first question in one of your previous writings:...

I think I found the answer to my second question in the following article by you:...

The good old AF-S 18-70 is very good (at least my exemplar, despite some slight decentering at the wide end), but has no VR. It is, however, nearly one stop wider at the tele end, therefore it ...

My exemplar is nearly very good even at 300mm. I say this as a dedicated pixel peeper  (70ppi) with a D7500. But of course, viewing conditions and personal standards are different and lenses vary...

Very clear and straightforward argument, thanks!

Dear Roger, thanks a lot for your very insightful articles. I know that this article is already quite a few months online, but I hope that this is still a good place to ask two questions.

I have...

I agree that it was most likely not "easy". Actually, I think that it is quite an engineering feat to put all the mechanics, motor(s), and electronics in an adapter without this dreaded tripod ...

Just as a side remark: Sony managed to create a nice adapter with full support for screw-drive AF (A mount) and a mechanical aperture lever in a compact format without any additional tripod mount ...
