Cosmicar Television Lens 25 mm 1:1.4 [C-mount]

25 mm is a standard focal length for micro four thirds cameras (eq. of 50 mm for Full Frame aka type 135). Luckily, there are many lenses with C-mount that would work perfectly. So far I mentioned only Fujian 25/1.4, that was a cheap tool available. Recently I've found a bargain Cosmicar Television Lens 25/1.4 with slightly distorted filter ring and oily aperture, but with perfect glass condition.

Carl Zeiss Jena DDR Tevidon 16 mm 1:1.8 [C-mount]

Tevidon 10/2 was a great pick! Later I've found Carl Zeiss Jena DDR Tevidon 16/1.8. A bit narrower lens from magnificent Tevidon family. This time it's so called "zebra" housing, because of polished stripes on focusing and aperture rings.
