A telephoto prime lens with a 135mm focal length and f/2.8 aperture for Rollei QBM mount cameras.
The Rollei Rolleinar-MC 135mm f/2.8 is a telephoto prime for the Rollei QBM (Quick Bayonet Mount) system, used on the Rolleiflex SL35 series of 35mm SLR cameras. MC indicates multi-coating. The Rollei QBM was produced in collaboration with Zeiss and Voigtlander and accepted both Rollei-branded and Zeiss SL-line lenses.
135mm focal length, f/2.8 maximum aperture, MC (Multi-Coated), Rollei QBM bayonet mount, designed for Rolleiflex SL35 and compatible cameras.
The Rolleinar 135mm f/2.8 MC is a fast telephoto prime for the QBM system delivering good portrait and sports telephoto performance. The Rollei QBM mount is a niche system; adapters to modern mirrorless mounts are available but less common than for Canon FD or Olympus OM. A practical vintage telephoto for SL35-system photographers.
Inspect for fungus, haze, and coating condition. Confirm QBM bayonet engagement and release. Check aperture blades for oil. Test focus helicoid smoothness.
