Nikon Helios 44-2 58mm f/2 №84251008 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. There are slightly cleaning marks on the glasses
