You are bidding for a Jupiter 85mm, f:2, L39 Leica Screw Fit, Rangefinder coupled Lens. 

It is also similar optically in design to the Zeiss Sonnar. 

It is in quite nice condition and the optics are clear, clean and fungus free, the aperture is clean and working ok.

It also comes with both the original front and rear lens caps although the front lens cap is a bit loose.

Many thanks for your interest!
