Helios 44 comparison. Which version is the best? (Vintage lens test)

There are many different versions of the iconic soviet lens, but which one should you buy? In this video I compare the ’Silver’ Helios 44 to the regular 44, the well known 44-2 and the later 44m-4. You can judge for yourself which Helios is the best, or maybe there isn’t any difference at all?
