Lens Overview — Minolta 100mm f/2.5 Tele Rokkor

The Minolta MC 100mm f/2.5 Tele Rokkor is a manual focus prime lens built for the Minolta SR mount, covering a full-frame image circle. With a fixed focal length of 100mm and a maximum aperture of f/2.5, it sits comfortably in telephoto territory — a range well suited to portraiture, detail work, and compressed perspective shooting. As a fully manual lens, focus is handled entirely by the photographer, with no autofocus mechanism present.

Image stabilization is listed as none, so steady shooting technique or a stable support is important, particularly when working at or near the maximum aperture. The lens accepts 55mm front filters, which makes it straightforward to use with a standard filter kit. Weighing 435g, it has a solid, substantial feel that reflects the build standards of its era.

The Minolta SR mount is the native fitting, though with the appropriate adapter this lens can be used on a variety of modern mirrorless and DSLR bodies that lack an SR mount natively. For photographers who value manual control and the deliberate shooting process that comes with a vintage prime, the MC 100mm f/2.5 Tele Rokkor offers a compelling combination of focal length and aperture in a well-constructed package.

Key Features — Minolta 100mm f/2.5 Tele Rokkor

Description — Minolta 100mm f/2.5 Tele Rokkor

The Minolta MC 100mm f/2.5 Tele Rokkor is a prime telephoto lens built for the Minolta SR mount, designed to cover a full-frame image circle. Its fixed 100mm focal length places it firmly in the telephoto range, while the f/2.5 maximum aperture gives the photographer meaningful control over depth of field. Focus is entirely manual, with no autofocus system — a characteristic that suits deliberate, considered shooting styles.

The lens weighs 435g, giving it a solid, confidence-inspiring feel in hand. A 55mm filter thread at the front makes it straightforward to add filters from a standard kit. There is no image stabilization, so technique and support matter when shooting at the wider aperture settings.

Originally designed for SLR camera systems, this lens can be adapted to modern mirrorless platforms using an appropriate Minolta SR mount adapter, opening it up to contemporary shooters looking for a classic telephoto prime.
