+1 , not all. For example Carl Zeiss Jena Tevidon 25mm f1.4 does not. _________________ -------------------------------

It is not a razor sharp lens, but renders colors and portraits nicely (maybe it is the pretty woman though )
Quite a few c-mount lenses do not vignette. It has to be tested out individiually. The shorter the focal length, the higher the chance for vignetting (1" or 25mm is usually the turning point). _________________ Klaus - Admin

Thx for commenting. This forum is really something special with members with genuine interest & and deep knowledge regarding the history and technology of lenses and photography. Very inspiring gang! Thank you!
All of my 25mm and 1 inch lenses in C-mount have a little vignetting, but can in some situations be a nice effect (flowers, portraits).
I am pleased to have the 25mm, 50mm & 75mm in this lens series.
And like Attila and some of you other guys have mentioned before, pretty girls can sell any lens _________________ Lars | Manuellfokus.no |

I agree, but I don't bother since it's always a possibility to crop to quadratic when post processing the image.

Can you post a couple showing the same vista? With lots of bouquet/bokeh?
Most examples of this occur with WA 35mm lenses, in my experience, admittedly not as extensive as some here. _________________ ---------------------------------
