Description — Minolta 18mm f/9.5
The Minolta UW Rokkor 18mm f/9.5 is a prime wide-angle lens built for the Minolta SR mount system. Operating at a fixed 18mm focal length with full-frame coverage, it delivers a broad field of view suited to landscape and wide-angle compositional work on compatible SLR cameras. The lens is manual focus only, placing full control of focus in the photographer's hands — a workflow that rewards patience and precision.
At a maximum aperture of f/9.5, light transmission is limited, meaning this lens is most at home in bright or controlled lighting conditions rather than challenging low-light scenarios. Weighing in at 350g, it remains manageable for field use without adding significant bulk to a camera kit. There is no image stabilization, and no filter thread size is specified in the available data.
For photographers working within the Minolta SR ecosystem who want a dedicated 18mm prime with a deliberately manual character, the UW Rokkor offers a fixed, wide perspective tied directly to that classic SLR mount.
