I have this lens and went to use t this afternoon.
I hope you don't mind me adding to yours.
I was gifted one of these in non working condition. It is now fully functioning thanks to my son.
I was trying it out on the lemon bush when some king parrots appeared at the feeder. It is amazing how close these birds will allow an unthreatening approach.
Even so, I have cropped the images of the parrots by almost half.
Here are the images.

These are excellent sample photos! Unfamiliar with this lens as well. So, thanks to OP and Oldhand for posting....I think.
(Another lens I didn't know I needed!)
Aside:
Other than the bubble machine that it is, as evident in the evening shots, the rest seemed oddly reminiscent of a M42 Auto Rikenon 50 f/1.7.
Always assumed it was made by Tomioka, but the swirly bokeh doesn't fit the pattern of known Tomioka-made 50 f/1.7 models, namely Yashinon. Those have the smooth melt away bokeh and are center sharp. The Rikenon is also a bit soft at f/1.7 like the above samples.
Now I wonder if it's a Cosina-made lens!
There is also a nearly identical 'EE' Rikenon except for that rear pin. That one seems to perform a bit sharper wide open.

Yes it does look a little like the Auto Rikenon, however it is smaller overall and has a smaller filter thread - 49mm vs 52mm.
Here are some comparisons.

The Topcor 50/1.4 seems to have a similar very bubbly bokeh like this lens .. so does the Fujinon 55mm f/2.2 and those lenses might be sharper

You might be right about sharpness (I have the Fujinon 50/2.2), but what makes this lens interesting is the fact that the bokeh looks like a mix of those soap bubble ones with the swirl effect of an Helios. _________________ Jaime Silva

Hello, good evening. I liked the sample photos that were posted. Do any of you know if the Cosinon F/1.8 50mm has the same rendering as this F/1.7 version? Both are M42 mount. These screenshots are the only information I could find about both lenses.

I take it they weren't mass produced? |

I am pretty sure there is not much difference between them. I think the Helios is a better lens on all counts except swirl which is near identical. Cosina wasn't a big brand but they did make a lot of third party. You can find the 50mm 1.7 in different guises.

Some version of the Rikenon 50mm 1.7 also look just like it: https://www.ebay.com/itm/Ricoh-Auto-Rikenon-50mm-f-1-7-M42-Screw-Mount-Prime-Lens/264805531806?hash=item3da7a3c09e:g:hh4AAOSw~xFfGbKg
And there were 2 different 50mm 1.7's from Cosina. I just have the 1.8 so I wouldn't know if there is a difference

Thanks for all the information. I appreciate it. You're right about the helios and I actually prefer it's build quality. Something about those silver lenses. I wasn't able to find the Carenar version on Ebay. I did check out that F/1.7 listing yesterday, but I didn't like the sellers reviews. I did read that Cosinon made lenses for the bigger brands. They didn't make many for themselves. Guess I'll take some test shots tomorrow, and see if I can reproduce the bokeh highlights the OP did with his shots. If it looks the same than I'll likely grab the Auto Rikenon 50mm F/1.7. As I really think it renders beautifully. |

I hope you don't mind me digging up the topic.
Recently I purchased the 50/1.7 along with its "brother" - the Revuenon 50/1.8. Neither has MC markings on them and the Revuenon does feel like it has no coating at all (transparent glass on the front element and also loss of contrast and a lot of flares). The Cosinon has some gold-ish coating that makes it look literally like Takumar and also causes pictures to be a bit warmer but I can't say if it's SC or MC.
A few samples from the Cosinon 50/1.7:
I also thought that I'll take a few shots and compare them head to head with the Takumar 55/1.8 which is obviously superior to both. The following pictures are unaltered in any way other than jpeg compression. The only ones that have a bit of postprocessing are the last 6 starry sky shots. However, all the settings (both: camera and postprocessing) for these pictures are exactly the same.

The Revuenon is sharper but they're both pretty close and the difference disappears at f3.5 or so. The one major difference, though, is that the Cosinon's colors are much warmer. |
