Lens Overview — Minolta 500mm f/8 RF
Key Features — Minolta 500mm f/8 RF
500mm Reflex Optical Design: Mirror (catadioptric) construction folds the optical path internally, allowing a 500mm focal length in a far more compact and lightweight package than conventional telephoto designs.
Fixed f/8 Maximum Aperture: A characteristic of reflex telephoto lenses, the fixed f/8 aperture keeps the design simple and compact, though it requires adequate light or faster ISO settings.
705g Compact Build: At 705g, this lens is notably lighter than traditional 500mm primes, making it practical for handheld use and travel.
Minolta MD Mount: Designed for Minolta MD mount bodies and widely adaptable to modern mirrorless systems from Sony, Fujifilm, and others via inexpensive third-party adapters.
Full Frame Coverage: Covers full frame sensors with no vignetting, and provides a true 500mm field of view on compatible bodies.
Manual Focus Only: All-manual focus operation gives the photographer precise control, suited to deliberate shooting at super telephoto distances.

Description — Minolta 500mm f/8 RF
The Minolta MD 500mm f/8 RF Rokkor-X is a prime super telephoto lens built for the Minolta MD mount and designed to cover full frame sensors. Its defining characteristic is the 500mm focal length paired with a fixed f/8 maximum aperture — a combination made possible by the reflex (mirror) optical design that keeps the overall weight down to just 705g. For a lens reaching 500mm, that weight figure is notably low and makes it a more portable choice compared to conventional telephoto primes of similar reach.
Focusing is entirely manual, placing full control in the photographer's hands, which suits methodical shooting approaches at long distances. There is no image stabilization, so disciplined technique or physical support is recommended to get sharp results at this focal length. The Minolta MD mount has broad adapter compatibility, opening this lens up to use on a range of modern camera platforms beyond its original Minolta system home.
No filter thread size is documented in the specifications.
