Consider the CV 40mm f1.4. A very good lens with a low price on the used market reflecting that it is shunned because it is not 35mm. Too many photographers never tried assuming it would not work because they did not have 40mm framelines or they assumed there was a discernible difference in the FOV between 35 and 40mm. A little bit of work with a file on the mount will bring up 35mm framelines which match the actual FOV (at least on a Zeiss Ikon).
I shot an entire project over a year with this lens, almost always wide open. See my South Apopka religion series at

Actually the 35mm slot in my M mount lens lineup is filled with this 40mm lens.
