Minolta's MC tele zoom — the 100-200mm f/5.6 MC Zoom Rokkor, a convenient early-70s telephoto zoom.
The Minolta MC Zoom Rokkor 100-200mm f/5.6 is a telephoto zoom manual-focus lens for Minolta reflex cameras from the MC generation of the early 1970s. The Zoom designation marks its variable focal length and MC the meter-coupled series. Covering short to medium telephoto, it was a convenient single-lens solution for distant subjects.
This is a manual-focus telephoto zoom covering 100-200mm with a constant maximum aperture of f/5.6 across the range, from the meter-coupled MC line. Only the focal range and aperture are stated as verified; other construction figures are not confirmed here and are omitted rather than guessed.
The 100-200mm range spans portrait to medium-telephoto framing, useful for portraits, distant wildlife and travel where carrying a single zoom is preferable to multiple primes. The modest constant f/5.6 aperture keeps the lens reasonably compact and holds exposure steady through the zoom, favouring good light or a support.
On the used market this is a common MC tele zoom Rokkor bought by collectors and users adapting vintage glass. Given its age and complexity, check the elements for haze, fungus and separation, confirm the zoom and focus actions move smoothly without excessive play, and verify the aperture works cleanly. Use an adapter for mirrorless mounting.
