Awesome budget lens by East Germany Aus Jena aka East German Zeiss factory

Aperture works, focus works

Shutter hold switch does not work, however does not affect functionally when used with included emount adapter

Does have what looks to be fungus or haze, and dust inside lens, tried my best to photograph. I used this lens as a budget macro setup and never noticed artifacts or visual problems, however your mileage may vary depending on your rig and shooting environment.

Great vintage lens with more life left in it.

Sold as is, no returns
