Super Super fast Canon C mount TV lens, TV-16 25mm f/0.78 aperture
its f/0.78 max aperture makes it among the fastest lens ever made in the history of the lenses.
This lens is a C TV/16mm screw mount for Super-16 digital shooters . please note the rear element of the lens extends quite far, which makes it difficult to achieve infinity focus on digital camera sensors with thick protective glass, meaning unmodified it may be more useful as a macro lens.
Some mechanical work is needed to enable infinity focus on various cameras but needs great expertise.
Decent shape with focusing working fine aperture works s it should and Optics look decent with light dust specs and may have light wipe marks.
