Sankyo kohki komura 135mm f2.0 M42

Fast full-frame short telephoto prime lens.

The 135mm f/2.0 lens with its very large lens opening has been an instant success with photographers seeking a medium focal length lens having maximum lens speed. This extra speed assures well exposed negatives and color slides in poor light. Brilliantly sharp results may be expected from this lens even at full aperture due to its fine corrections.

The Komura 135 mm f/ 2  is a fast telephoto prime lens for 35 mm SLR cameras.

It is equipped with a 18-blade aperture and an aperture preset ring.  Its optical scheme is similar to that of Ernostar (it is nicknamed King of Ernostars on western message boards).
