Sigma 30mm 2.8 EX DN works very well on the A7RII

I was planning to buy the Sony FE 28 2.0 but I was pleasantly surprised

when I screwed on the Sigma 30 mm. No vigneting at all, very sharp

and half the price of the Sony 28.

 

Some examples, uncropped:

I use the same lens on the old A7r, and it is perfect only if you:

- remove the rear baffle (just 3 screws, easy peasy)

- crop the sides of the image in a 4x5" proportion (a thing that I often tend to do anyway, regardless of the lens).

 

Otherwise there is pretty significant vignetting at f/4 and below.

 

I know this might be a dumb question, but did you turn off the "Auto" setting to avoid shooting the lens in crop mode?

I was thinking OP had might have removed the baffle, but your suspicion seems more credible.  In any case, even in crop mode, the a7Rii has more resolution than my NEX-6

You are right. The APS-C/Super 35 mm option was set on.

I was confused about this since it is different from the setting

on the A7 and A7R which is called APS-size. The resulting

images are 5168x3448 or 18 Mpix. However, the angle

does not differ very much from 30 mm. Still pleased with result though.
