Nice comparison Cipher. Lens looks decent to very good depending on aperture used.
Thanks for sharing,

Cosmicar 25mm f1.4

The last of the "Three Amigos", these c-mount TV lenses were sold in the 70s under a variety of names: Cosmicar, Concord, Ampex, General Electric, and others. Generally better performers than the cheap cctv lenses now sold under that name.

Here is an example of an image at f4 (optimum):

Here is at f1.4:

Here are the three of them together (25mm f1.4, 50mm f1.4, 75mm f1.9):

There are two versions of each focal length, one with f1.4 maximum and one with f1.9 or 1.8 maximum. They all appear to be of the same design, I got mine for $40-$60-$100 on ebay. There is a black variation of these lenses as well, it may have a different design. I found them to be almost as sharp as the 06, and a little less contrasty, with better bokeh. They all have a nice glow wide open. Not shown are the hoods, the 25mm takes a 35.5mm thread, the 50mm takes a 40.5 and the 75mm takes a 46mm.
