Nikon Helios 44-2 58mm f/2 №86020974 Nikon F-mount

 The flange focal distance of this lens has been changed to 46.5mm without changing the optical properties. Infinity is available on cameras with Nikon F-mount. The aperture control ring has been redesigned and now shows the correct aperture value, and not the other way around, as on all standard Helios 44-2. Restored using modern lubricants. The glass is washed with Zeiss products inside and out. The ends of the glass were blackened to enhance the contrast of the lens.
