Mitakon MC 80-200mm f/4.5 - vintage macro-focusing manual zoom across four SLR mounts
Mitakon was a third-party lens brand sold through camera importers in the 1970s-80s, alongside contemporaries like Vivitar, Soligor and Hanimex. This 80-200mm macro-focusing zoom was a budget telephoto for SLR owners wanting one lens for portraits through to close-up work.
A manual-focus zoom covering 80-200mm at a constant f/4.5, with multi-coated optics badged MC. A macro switch near the long end allows close focusing, and the lens takes 52mm filters. It was sold in Canon FD, Pentax K, Minolta MD and Olympus OM mounts.
Optically it is soft wide open, sharpening by around f/8, and the macro mode suits framing flexibility more than critical resolution. Contrast is moderate and flare control is basic against backlighting, typical of multi-coated consumer zooms of the period.
These turn up cheaply through UK clearance sellers and estate sales, sometimes bundled with a body. Check the zoom and macro-switch action for stiffness or grease on the aperture blades, inspect the rear element for fungus, and confirm the aperture clicks cleanly.
