TV lenses may not have proper coatings for color reproduction on film since
they are designed to optimize "TV" spectrum. Probably do a test and find out
because those lenses are dirt cheap. Also, the distance between the back
element and the film plane is almost certainly wrong for any film camera
(CCTV cameras can be easly adjusted for this distance for different lenses)
and adapter rings might cost more than a lens that would work properly, if
you could find any of the proper dimension. I just did some tests on for my
Bolex with some TV lenses and none of them would even focus properly. I may
be able to do some adjustments on the lenses themselves, but it still does
not address the color reproduction issues. CCD cameras are very sensitive to
infrared, so they may have compensation for that which might affect the
visible spectrum reds and facial tones, too.

has anybody used a Cosmicar 8.5mm c mount lens. I saw a couple up on ebay
and was wondering if anyone has used this lens before and can relate their
opinions regarding sharpness, function, etc. I thought it might make a
good
prime lens for my ACL. one of the ads mentioned it will cover super 16.
thanks.
