My Zenitar 16mm f/2.8

I use Zenitar 16mm f/2.8 for many years, mainly with film cameras.

@ Alfa2, Am I right in thinking that the second pic has been cropped/cut so that it only shows part of a photo?

No, it was not cropped.

Really? To me it looks so 'undistorted' that it looks like it was done with a 'normal' ( though very) wide angle lens, such as a 20mm or something!

Well done for not just satying with the 'fisheye'/semi-'fisheye' look.
