Overview

The Sankor 135mm f/2.8 is praised for being very sharp with pleasant bokeh, though contrast is low wide open (iangreenhalgh1). It is a heavy lens (Nordenstro). Optical quality varies by version; the one resembling the 105mm f/2.5 is not as good as this model, while an older M42 version is superior (Nordenstro). It suits users who value sharpness and bokeh over contrast, and who can handle its weight.
