Hi all, I bought an m10 with 14-42 EZ + Panasonic 20mm and now I am looking for some manual lenses for fun. I found good Pentax-A 50mm f1.7 and Tokina 70-210mm f/4-5.6 for relatively cheap and I will certainly get the latter. At home I dug up a Helios 44-2 58mm f2 and was wondering whether it is worth getting the Pentax. As of now, I don't have any adapters for either. What do you think?
