I'm interested in getting a C Mount lens and found a lot of articles for the "Fujian CCTV 1.7/35".
The Fujian seems to work well, but I also found 25mm and 16mm lenses with aperture as high as F/1.2 or F/1.4
I have a 50mm Canon FD lens and its way too wide for anything but portraits.

Will a 16mm C Mount CCTV lens work without significant distortion requiring cropping ?

I found a 8mm samples with a lot of vignetting.

thanks.

Don't bother. Unless you like cropping.

CCTV lenses are made for a 1" sensor. At 35mm there is a hint of vignetting, which progressively gets worst at shorter FLs. Longer FL does not vignet.
