Flower photos from the Petri CC Auto 55mm 1.8 lens

Hi. I've had my M42 mount Petri 55mm for a while but haven't taken it out too much. I know it has a good reputation and I went ahead and cleaned it the other day by removing the front element, along with my Orikkor 50/2. It just has to be one of my favourite lenses really. It's really soft and glowy wide open, but even stopping down a bit improves sharpness greatly. All in all, a beautiful piece of glass and one I should use more often. Two at f1.8, showing that softness and glow, and one at f5.6 to show how sharpness and contrast improves greatly.

Here are some flower photos from the front garden using the Petri on my Sony Nex 6. Straight out of camera JPGs with no extra processing done. Focus is on the yellow flower. Not great photos, obviously, but demonstrates what an old beauty this lens really is:

Very pleasing results for sure.
That second image has quite beautiful rendering and buttery smooth bokeh.

I sold mine. Rolling Eyes

But I'll find another. It's a wonderful lens.

Could you post another couple of pictures where the bokeh is visible?

Thank you

Same Petri ,bokeh? Hm first lens I have with this kind of bokeh, definitely needs more testing done -

Yes, I've found it to be pretty busy as far as bokeh goes, but not unattractive. It's pretty smooth really. What I like is that at f1.8 it's a very different lens to when it's stopped down. It gives anyone a lot of flexibility out there in the field. My biggest gripe is that it feels a little fragile. That said, my version is all metal, small, and has lasted for nearly 60 years, so it must be solid enough.

The Petri Orrikor I have is probably one of the most attractive 50s I have, and I have lots of 50s. It's a tiny thing and looks much like an old rangefinder lens. My copy is in pretty good condition really. Focus is a touch on the stiffer side, but still usable. There was one fungus spot on the front of the second element, but I cleaned it off.

Nice sharpness and highlights, not easy prone to reflections - I wouldn't call it harsh bokeh, but definitely needs a good adapter to check it out - my version is the all metal ring, but it's so small and light comparing with other 50's 1.7 - mine it's got very smooth focus, not much used before, and nice coatings for a 70's lens (not sure what year is exactly ) - I do have the large electric version of the 135 mm 2.8 ,but needs some cleaning ,lots of dust

Heck I really need to get mine in use.. 😆

Only (nex) adapters I've seen are pretty pricey alas..

I did find an old (possibly custom) metal petri>m42 adapter once.. Only to find someone had wedged an m42>petri adapter onto it.. 😭😭😭😭

My Petri 55 1.8 comes with a metal ring, just like Minolta 55 1.7 PF, but I've seen same front lens with rubber or leather on the focus ring (this last one in M42), wonder if would be all the same lens, as they share same front ring,or might be another maker?

I have the same lens which, after I purchased it, had it CLA'd and it's now one of my favourite 55mm's.
Glowy wide open but from f4 is razor sharp.
