Auto Tele Seimar 135mm f/2.8

A classic fast 135mm portrait telephoto — the Auto Tele Seimar f/2.8 in the universal M42 screw mount. Seimar was one of the many independent Japanese optical brands of the manual-focus era, and this 135/2.8 is a bright, easy-to-use short tele ideal for portraits, details and compression. It has been recently cleaned and the optics are clean. Best of all, it adapts readily to just about any modern mirrorless camera with an inexpensive M42 adapter.
