Adapting Helios 44M vintage lens to Canon R50

[RomMarks]

I recently bought the Helios 44M model from 1976 to use on my R50, I would like to ask what is the best to chose adapter considering flange depth of the lens and to not lose infinity focus on it while using.

Can I go for this one screw mount:

 Or this type of more deeper mount:

 Lens have a 45.5mm Flange focal distance (not sure if this enough info for someone to help me)

Thanks in advance

Wow, such a great story Gary! Amazing previlege to be handed such a great bag of cameras and lenses! Very fortunate I would say! 🙂

I saw those videos prior to buying the 44M so I took my chance finding that one specificaly, but what I've learned too is that they are all great to be fair, dispite the diferent fabrication quality between them! I guess they will all need some servicing by a professional so they do not get ruined in the process of course.

About the rolls that is very good to know we still can use them after so many years, as long as they were contained and preserved I guess. I also have a few with 10+ years old that I will get to use along with the Zenit-E thanks to your knowledge about it! 

Thank you and take care.

P.S.: I will share some of my photos with the Helios 44M with you wen I get it!

Gary, the first two numbers of the serial nr is the year of fabrication (check yours), that symbol with the arrow shows it was made on the Valday factory, less quality fabrication because they were mass produced there. Still quality image of course!
