Minolta's late MD wide zoom — the 24-50mm f/4, a constant-aperture wide-to-normal zoom from the early 80s.
The Minolta MD Zoom 24-50mm f/4 is a wide-angle zoom manual-focus lens for Minolta reflex cameras from the final MD generation of the early 1980s, when Minolta dropped the Rokkor name from most barrels. Covering wide to normal with a constant aperture, it was a versatile wide zoom for landscape and travel in the mature MD system.
This is a manual-focus wide-angle zoom covering 24-50mm with a constant maximum aperture of f/4 across the range, from the last MD line. Only the focal range and aperture are affirmed; other construction figures are not confirmed here and are omitted rather than guessed. It succeeded the earlier MD Zoom Rokkor 24-50mm f/4.
The 24-50mm range spans a genuine wide angle through to normal, useful for landscapes, architecture and travel where a single lens can cover most framing needs. The constant f/4 aperture holds exposure steady through the zoom, and the wide end gives more sweep than a typical 28mm-based zoom of the era.
On the used market this is an uncommon and well-regarded final-generation MD wide zoom sought by collectors and travellers adapting vintage glass. Given its complexity and age, check the many elements for haze, fungus and separation, confirm the zoom and focus actions are smooth without excessive play, and verify the aperture works cleanly before buying.
