I have my aluminum Helios 44 2/58mm lens with M39 mount for sale. This is not the more famous 13 blade version, it's the 8 blade but the bokeh with this lens is still nice. The aperture blades are clean, there is no mold of fungus, there are some thin cleaning marks on the front element but I haven't noticed any degradation of images taken with the lens. Sorry about the cropping on the third photo, that was the last shot on the roll and it got slightly mangled at the one hour photo lab. Front and rear caps included as well as an M39-M42 adapter. $55 via Paypal or Postal money order includes shipping in the U.S., P.M. for an international shipping rate via Paypal.
