Interesting as I got a helios 44-2 from that guy and I'm pretty pleased. The outer ring sets the max aperture and isnt ment to turn all the time as you use the 2nd ring which adjusts your ap from min to max. then you have the focus ring near the base..
Been ok for me.. unless the outer ring isnt supposed to 'lock'..
This is my first helios so i just made the assumption that this is how it is supposed to work, which hasnt hindered my shooting.
I know how the preset aperture ring works. On the one he sent me, it's nearly impossible to turn. Furthermore, he tried to convince me they were all made like that. Moreover, he left me nasty feedback (which ebay removed because it was in violation of their policies).
Prior to this purchase, I had bought a Jupiter-9 lens from him which was fine. It's a gamble with him. A feedback score of 98.4% is not a good sign at all. Fortunately, ebay's resolution center does work well, as long as you follow its guidelines.
He also sent me several angry messages. I sent him a link to this thread.
