An old lens from half frame Zeiss Tennax

I guss it's fastest/wide sonnar as fas as I know.

I used wobble adapter, so sharpnes at edges cannot be achived.

I have posted about this lens when it still in original shape in HERE
It was cut and I made a 52mm screw on back part, to fit my 52mm helicoid.

Carl Zeiss Jena Prokinar 50/1,4

This Prokinar serie was designed for 16 mm film projector. It's size is smaller than visionar 55/1,6 (I thought it was same size). Turned out to be easier to adapt, no need to make destructive modification.

It has good sharpness at center even at infinity. Calm Swirly, not like other 16mm projector lens at similar focal length.
