Minolta's early medium tele — the 135mm f/4 Tele Rokkor-TC, a first-generation SR portrait lens.
The Minolta Tele Rokkor-TC 135mm f/4 is a telephoto manual-focus lens for Minolta reflex cameras from the late 1950s, part of the first generation of the SR system. The Tele prefix denotes its telephoto role, and 135mm was a staple portrait and medium-telephoto length that most system makers offered, this being Minolta's early entry.
This is a manual-focus telephoto lens with a 135mm focal length and a maximum aperture of f/4. The TC code encodes the element and group configuration in Minolta's naming scheme. Only the focal length and aperture are stated as verified; other construction details for this early model are not confirmed and are therefore left out.
At 135mm the lens gives useful reach for portraits, candid work and distant subjects, with compression that flatters faces and isolates the subject from the background. A maximum aperture of f/4 keeps it compact and manageable, making it a practical medium telephoto for daylight photography and travel.
On the used market this is a common and inexpensive early tele Rokkor, of interest to collectors and those adapting vintage lenses. Given its age, inspect for haze, fungus and separation, verify the aperture is dry and snaps cleanly, and check the focus helicoid runs smoothly. Examine the coating for cleaning marks, and fit a suitable adapter for use on mirrorless bodies.
