Pentacon Auto 135mm f/2.8 MC - Good Condition | The Legendary "Bokeh Monster"

The Pentacon Auto 135mm f/2.8 MC is one of the most celebrated telephoto prime lenses of the analog era. Originating from the precision factories of East Germany, this lens is famously nicknamed the "Bokeh Monster" due to its ability to produce incredibly smooth, creamy background blur. This Multi-Coated (MC) version features advanced optical coatings that improve contrast and significantly reduce flare and ghosting. With its fast f/2.8 aperture and telephoto compression, it is a premier choice for portrait photographers who want to isolate their subject with a timeless, artistic aesthetic. Its robust all-metal construction and precise manual focus ring make it a favorite for both film purists and digital mirrorless adapters.

Specialist Note "The Pentacon 135mm f/2.8 is a staple in the world of vintage glass. It is world-renowned for its 'rendering'—the way it transitions from the sharp subject to the blurred background is almost painterly. Unlike many modern lenses that feel clinical, the Pentacon has a distinct character that adds soul to portraits. This MC version is particularly desirable because it handles tricky lighting much better than the earlier versions. Whether you're shooting on an old Praktica or adapting it to a Sony or Fujifilm digital body, the mechanical feel of the focus throw is absolutely superb."

Condition Report Good condition. The lens barrel (S/N: 6318481) shows normal signs of light use and minor surface character consistent with its vintage age. The optics are clear, free from fungus, haze, or scratches. The focus ring is smooth and well-dampened, and the aperture blades are clean and snappy. The integrated lens hood slides and stays in place correctly.
