Classic Vintage Helios 44-2 Lens (used but CLA'd)
It's a 58mm f/2.0 Russian bokeh monster!
The 44-2 Helios has developed quite a following for photographing people because of it's beautiful rendering and bokeh. They are quite often adapted for cinema use for those reasons. This lens is in M42 mount. You can adapt this lens easily to Canon and Nikon DSLR's with a suitable adapter (but with some Nikon models you will not be able to focus to infinity).
I have a limited supply of these vintage Helios 44-2 lenses available. They were hand selected for performance, and have all been completely gone through by a camera technician and will have smooth aperture adjustment, and focus ring operation. Both front and rear caps are included.
