Interesting 35mm focal lenght lens made for 35mm Konvas film camera. Super 35mm is about the same size of APS-C, but the lens covers fullframe.

First snapshop from A7 II (just rezeissed) Laughing

Another, bokeh is really smooth... (click for bigger)


Landscape test (just rezeissed again) Smile You can see some vignetting and weakness here in the corners, but not bad at all considering this is with fulllframe.

Nice rendering!
Lens was used on KS-50b camera and for aerial photo.
I thought it would vignette like helios-33 (35/2) but it doesn't, whereas they share double gauss diagram.
I have another 35mm cine lens (oks1-35-1), which has different design (more like Uran), cover better than Helios 33, but not as much as yours.

You have this urge to stuff tiny lenses to unsuspecting Industars? Very Happy

But the results are great.

Industars are great cheap lenses perfect for projects like this whoever made it. (I bought it like this) Wink
It is nicely done. MFD is really great too, approx. 25cm and even half of that (10 - 15cm) with focus adapter.

Hello. Let me ask in this thread. What does the Cyrillic 'F' in the name of this RO4-1F lens stand for.
