C(iné) Mount lenses made for film movie cameras should not be used on video cameras and vice versa. The designers have left a little axial chromatic aberration that colour films perfectly fit to.
I'm not sure about that, primary axial CA (red and blue) is corrected out on all the lenses I examine, including professional 16 and 35mm ones, the typical chromatic aberration you'll find in even some modern lenses is secondary lateral, which manifests as purple fringing. Where have you read that film lenses had deliberate axial CA left in the design? Professional 35mm lenses like S4s or Ultra Primes were designed for film cameras but have transferred just fine across to digital cameras, as have many others. The main issues tend to be telecentricity, which isn't an issue with film but is preferred by digital sensors, and aberrations introduced by digital camera optical low pass filters (a bit like the Bolex prism problem), but I've never heard of "film" lenses having built-in axial CA.
@Jon: The problem with most CCTV or machine vision lenses is that they are designed for different applications than film-making. Older ones had far lower resolution specifications than 16 mm film, newer ones are computer-designed to give the best resolution/mtf score for least cost, which results in lenses like the Red Pro Primes (only on a far cheaper scale) which nobody actually likes the look of. Personally I'd avoid them, but some people seem to find them OK, they can certainly be cheap sometimes. Watch out for CS mounts that look like C mounts but have a shorter flange depth and so won't focus past a few meters, and others that don't have an iris.
Regarding the Berthiot Lytars, they were a budget line, with pretty average build quality in my experience. One of the biggest determiners of lens image quality is whether the elements are centred relative to each other and the lens mount, something called centration. With small lenses like C mounts it becomes even more important, and the higher quality lines tended to spend more time getting that right. Others will be more hit and miss. Poor servicing can also introduce decentration, and many C mounts have focus thread wear, which can cause image shift as the focus direction is changed.
The reality is that buying 50+ year old lenses that were primarily made for amateur cameras is a gamble, try one and sell it on if it doesn't please you.
