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 ...
I tryed to take photos of the night sky but it does not shoot since it does not have nothing to focus on. Canon R50 with original Canon lens 18-45mm withour AF/MF button. What can I do? Thanks
