Let me introduce you to an excellent vintage lens, production of the USSR.
 
Helios 44M-4 58mm F/2.0 USSR Lens For NIKON! Infinity Focus is!!!

Artistic portrait lens with good sharpness and beautiful swirling bokeh.

Helios 44M-4 is a great lens for SLR cameras, produced in Soviet Union. Based on the lens Carl Zeiss Biotar 2/58.

The photo is of the actual item for sale!

Included is an adapter for Nikon. Adjustment has been made for the Nikon working segment! Focuses to infinity!

Attention! On full-frame cameras, it can touch the mirror when focusing on infinity!
When shooting a portrait, there is no such problem.

During operation, do not try to screw in the protruding rear lens block. In this way, you violate the infinity adjustment!

The lens is supplied with new accessories, depending on availability, caps may not be inscribed.
