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.

Cosmicar Television Lens 12.5 mm 1:1.9 [C-mount]

After testing Tevidon 10/2 I got my hands on Cosmicar 12.5/1.9. It's a bit narrower lens, produced in Japan with C-mount. It's easily adaptable for Micro Four Thirds. All you need is a simple C-MFT adapter, no need for additional dedicated mounts as for Tevidon.
