the lens

Schneider Kreuznach Super-Cinelux 35/2 MC

From official PDF sheet HERE

One thing I didn't expected about this lens is the size, I thought it has smaller/shorter barrel than 62,5mm ES cinelux. I was wrong. It's longer, and even has heavier hood. make it handsome lens though.

So far, the results ;

• Sharp as expected
• It has relative wide dof, good for indoor meeting, streetshot etc.
• Nice flare
• some CA appear which is acceptable

The first 2 were shot with Sony a6000

The rest pictures below with NEX5

the flare

Isco Optic Ultra Star HD 65mm

The lens doesn't has description about the maximum light can through, which is usually indicated with the "F" letter. But the rear optic indicate that it has at least f2 like other isco lenses. f2,4 has smaller glass.

the lens identity

It's sharp. yes. at close distance to infinity
