CZJ-branded Praktica 135mm — the multi-coated f/2.8 telephoto from Carl Zeiss Jena.
The Praktica 135mm f/2.8 MC CZ Jena is a telephoto prime bearing Praktica and Carl Zeiss Jena co-branding, with MC (multi-coating) applied to the elements. The CZ Jena designation confirms Carl Zeiss Jena glass in a Praktica-branded product.
The lens delivers 135mm at f/2.8 maximum aperture with MC multi-coating, a null/unspecified mount in the database, manual focus and aperture, and full-frame coverage. The Carl Zeiss Jena optical formula applies Zeiss quality within Praktica distribution.
The MC CZ Jena combination designates the Carl Zeiss Jena optical design with multi-layer coating applied — a step above single-coated Praktica lenses in flare control. The 135mm f/2.8 provides fast telephoto for portrait and documentary work.
Identify mount type from physical inspection — likely Praktica Bayonet or PB. Test aperture blade operation at f/2.8. Inspect MC coating condition. Verify mount for adapter selection.
