Carl Zeiss-Opton Biogon T 35mm Lens f/2.8 for Contax Rangefinder series. Previously used with a Contax IIIa.

Lens is in great condition and has been stored well for the last few years.

Aperture blades are smooth and open well at all stops.

There is a very small black speck in the glass, I can't say if it affects the picture quality. Otherwise the glass is incredibly clean whinnies haze, mold or fungus.

Comes with original metal lens cap and back.
