>>3108195"Pen F M42 adapter"
Is it that hard to google?
Why would you even want to do this? Why put some cheapo fuckhueg slav lens on a beautiful little Pen F?
Why is some adapted lens the second choice after the 40/1.4? The 38/1.8 isn't that expensive. And the only redeeming attribute of a Helios is the swirly bokeh, which isn't visible on half frame.
