Went to a dusk walk with the lens and the Sony A7R. It was almost dark, so I have increased the brightness. The vignetting is heavy even the hood is Konica original.
I heard that the lens is rare, and am not sure whether I have brought out the potential of it (learning, still Wink). looks like the lens loves bright light. Will post more when I have chance to take pictures in strong light.







This picture was taken with X1.


Hello. I have the same lens as yours and shoot with it on film. I have a question for you. Is it possible for you to take measurements of your hood? I want to pick up some kind of analogue of this hood.

I had this shade and use with thw 28 mm lnes

How does the 21/2,8 compare with the oldest version F/4?

For another WA lens I checked some old magazine test and then this thread and your message on dpreview's adapted lenses forum appeared. The old magazine test of the Konica AR 21mm 2.8 has an odd resolution rise at 4.0, one that makes you wonder of a mistake in the text. Any sign of that spike in practice? Contrast measurement follows more the usual curve.

I have to try and take some pics at f4, i mostly use this lens at f8 or f11 to "minimize" field curvature.

Not too shabby, especially for an older lens with this focal length.
