Olympus F.Zuiko 2/35 from PEN EM

Does anyone know anything about this lens? I wasn't able to find out anything about it, just the specs of the camera. Anyone owned a PEN EM and can comment on it's IQ?

I'm gonna mount it for my NEX, I found it in a box of junk I've had for ages.

Cannot comment on the EM specifically, but can point into a direction for mounting: L39 to NEX adapter, remove the L39 ring from it and you have those 3 screws to securely tighten the lens inside it. You might get beyond infinity because of the shorter register distance of NEX compared to MFT but I don't think you need the MFD on this lens?

The same looking 32mm f/1.7 from an PEN EED I had was very sharp at f/2.8, I doubt this one will be a huge difference.

Also if it renders the same you won't like the bokeh. Does this one have a square aperture as well?

Thanks for the tips Fabian.

I removed the worst of the three lenses - four screws holds it on. This one has a dodgy aperture and is in fairly rough shape but has great glass. Took me a long time to dismantle the damn thing and remove the shutter blades. Then the only way I could fix the aperture was to remove one of the blades, so it now has a 5-bladed teardrop-shaped iris. I got it back together but now the helicoid seems to be reassembled wrong - it turns but I don't see anything moving back and forth and the aperture ring is really loose and wobbly, so I've turned it no junk, but it does still work, just doesn't focus and has a weird aperture. Oh well, learned a load of lessons about how to take it apart an put it back together, so I'll do better with the other two.

A quick test shot at ISO 800 wide open looks promising:

Cool! Those Zuikos almost always look good!

I had the same problem, just disassemble it, put some thought in it and try again. There could be some small bended plate screwed at the inside of the back of the lens that keeps the helicoid in place when turning so it moves forward and backward, maybe that's the culprit.

Cheers guys. Some more wide open samples I quickly shot today. I really like it, it's very sharp, has strong contrast and very smooth, pleasing bokeh.

Results looks very Zuiko'ish for sure, you should try to get some hasslefree Pen f lenses also (yes the prices are sky high on some of them, but they are special).

Try to get the 100mm 3.5 Pen lens, a stunning short tele still at reasonable price. Wink

A real sleeper.

Se my results when shooting raw with this lens on my OM-D
