135mm · f/2.8
The Tamron 135mm f/2.8 T mount model 680 is a vintage telephoto prime praised for its solid, compact build and smooth focus with a long throw. Optically, it delivers smooth bokeh and good corner sharpness, but is a little soft wide open with minor fringing; stopping to f/4 improves sharpness and contrast. It suits photographers who enjoy a slower, intentional shooting style for portraits and compressed landscapes, and works well on modern mirrorless cameras with an adapter.
