Kern-Paillard Yvar 75/2,8 AR

This lens is from Bolex cine camera.
It has C mount mount.
Common character of this C mount type lens is sharp at center only when it's being used in digital camera, APSC or m4/3. edges will get swirled and very soft.
It doesn't happen with this lens.
This image below shows on left side still has detail.

Bokeh type is not so special, but looks good for a f2,8 maximum aperture lens.

The lens has some fungus and haze
So I must avoid strong light

I think it's nice for portrait lens.

Paillard-Bolex 70/1,6, Hifi projector lens

Bolex HiFi projection lens for 16mm Bolex projectors >Bolex S221 and S321 <
According to this source The S221 projector made in 1960s, S321 was made in 1968. so it goes for the lens, let's say it was made between 1960-1968.

Similar character with Taylor hobson 16mm projector lenses, and common C mount lenses like Cosmicar 75mm, Soligor, Elitar etc at wide open of course. I tried Kern Paillard 75/2,8  C mount lens, this lens is better.. 
At least I know two version of this lens. The other version has bigger indention on body. I dont know the difference yet. My friend has the other version. Someday I will compare both.
All shots with NEX

You can see fall off on corners. This was at closest distance and wide open. If I turn aperture to smaller it become vignette, getting stronger in smallest aperture. All wide open.

This is not in minimum focus distance, you can see vignette getting stronger than 1rst picture.
