Rare Carl Zeiss Jena Biotar 2/5.8cm red T 17 blades from 1948 BT58_2b design. Black edition.
The Biotar 2/5.8cm was probably the highest quality lens available for the Praktiflex. The six-lens was available in the usual chrome-colored version and later also in black. The calculation of the optics goes back to the 10/19/1936.
This lens was certainly preferred by professional working or very ambitious amateur photographers. Today, the lenses can be found by collectors, but mostly in a very bad condition. The black variant in particular seems to be very rare in good condition.
Of the Praktiflex optics, the Biotar was probably the most expensive lens with a normal focal length.

This model is the most sought after because it produces beautiful bokeh that modern photographers find desirable. The seventeen aperture blades create smooth circular transitions in the out of focus areas of an image, resulting in a creamy smooth bokeh. The bokeh resembles that of the Soviet Helios 44, and I will leave it up to others to argue the differences between the two. It doesn’t produce as much bokeh swirl as does the Helios, but will produce swirl given the right conditions. Optically it closely resembles images produced by the Biotar 75mm f/1.5, though not as dramatic.
Lens shows some signs of prior use and is in very good condition. Shows some scuffing, some small scratches, no dings, no indentations. Aperture setting moves smooth. The elements are overall in good condition. Minor cleaning marks, tiny scratches, no haze, no fungus, no separation. Shows few dust particles inside. Aperture blades show minor wear and few oil on them. Lens comes with caps. Focus turns smooth.
Nice high quality lens. 17 blades aperture.
