Pentacon's auto 100mm f/2.8 — an East German M42 portrait telephoto with round-aperture bokeh.

The Pentacon auto 100mm f/2.8 is an East German short-telephoto prime made in M42 mount by the Pentacon combine in Dresden. Descended from the Meyer-Optik Orestor 100mm design, it was a portrait-length telephoto in the Pentacon range and is noted among vintage users for its rendering.

This is a manual-focus M42 screw-mount lens with a 100mm focal length and a maximum aperture of f/2.8, with an automatic diaphragm marked by the auto designation. Focus and aperture are set by hand on the barrel, and these lenses are known for a many-bladed aperture giving round openings. It is an all-metal short telephoto. Exact element figures are not asserted here beyond the verified focal length and aperture.

At 100mm f/2.8 the lens is a portrait and short-telephoto tool, giving flattering compressed perspective and good subject isolation. Its many-bladed aperture produces notably round out-of-focus highlights, and it is popular among vintage users for pleasant, characterful bokeh that suits portraits and distant detail.

Used copies are affordable and popular for adapted portraiture. Inspect for haze, fungus and cleaning marks, confirm the many aperture blades are clean and oil-free, and check the aperture-ring and focus feel over the longer travel. Verify the M42 mount. An M42 adapter makes it a well-liked manual portrait telephoto on mirrorless.
