SMC Takumar 135mm f/3.5 — Moderate mid-range tele-lens, has most advantages of faster 135mm f/2·5 lens, but offers lower cost for those who do not need extra f-stop for low-light shooting. One of the most popular tele-lenses. Traditional long-focus design.2

The same optical design as the Super-Takumar 1:3.5/135 (Mark II) lens.

Review

An excellent lens, but not really better than the Takumar 1:3.5/135 (Mark II) for portraits and way shorter than the Tele-Takumar 1:5.6/200 as a handheld telephoto lens. Anyway, a very common lens that can be had for very little and thus well worth grabbing on your local auction website.
