Carl Zeiss Jena B 2/58 Analogue camera

Up for auction is a legendary vintage manual focus portrait lens: the Carl Zeiss Jena B 2/58 (Biotar 58mm f/2), serial number 4292179. This is the desirable export version marked with "B" due to historical trademark restrictions, carrying the prestigious Q1 (1st quality) red mark.

This specific copy comes in the rare and collectible Praktina mount with a semi-automatic diaphragm mechanism. It features a beautifully rounded 10-blade aperture that ensures smooth, circular out-of-focus highlights and produces the iconic, world-famous "swirly bokeh".

Condition Report:

Cosmetic condition:

Very good vintage condition with minor, normal signs of handling on the chrome/aluminum barrel. The "Germany" engraving is clearly legible.Mechanical condition: The focus ring and aperture adjustment ring rotate. The multi-blade aperture mechanism (10 blades) is snappy and opens symmetrically.

Optical condition:

The front and rear glass elements are in good cosmetic shape for their age. There are no deep scratches, no fungus, and no haze. As clearly demonstrated in the dedicated backlight photo, there is some minor internal dust present, which is typical and expected for a vintage lens of this era and does not affect image quality. An absolute must-have piece for vintage lens collectors or modern mirrorless shooters using a Praktina adapter.

Shipping:

Will be safely and securely packed to prevent any damage during transit. Shipped worldwide with a reliable tracking number.
