Sony, Praktica, Pentacon Practicar 1.8 50mm + balg + adapter PB-NEX + doos Camera lens

I am selling the very extensive photography collection of my late father. He was a passionate hobby photographer for 65 years and in recent years also experimented with alternative lenses on digital cameras. He would disassemble the lenses if necessary for cleaning or repair. I am not a photography expert myself, so I describe the lot as thoroughly as possible, including as many detailed photos as possible.
READ the information below and carefully examine the attached photos to avoid any misunderstandings.

For the serious collector or macro photographer: this set combines classic DDR optics with modern usability. The Pentacon Prakticar 50 mm f/1.8 MC in Praktica-B mount is a solid manual lens with pleasing bokeh and reliable optics.
What makes this set special is the inclusion of a Praktica-B bellows, which allows you to take macro shots with high magnification. The lens can therefore focus much closer to the subject than usual, making it ideal for coins, stamps, insects, or product photography. Thanks to the manual diaphragm and focus ring, you retain full control.
Additionally, the set comes with a PB-NEX adapter, allowing the lens and bellows to be used directly on modern Sony E-mount mirrorless cameras. This way, you can combine vintage DDR optics with modern digital photography.
As an additional collectible value, the bellows are supplied in the original box, making the set not only practically usable but also fully complete and attractive to collectors.
Some dust is visible in the lens; focus and diaphragm work fine.

Attention: it comes without a camera.
Look carefully at the detail photos.


Combined shipping of lots is possible, but only if they are won in the same auction. This is to save on shipping costs.
