Overview

The Soligor 300mm f/5.5 is a vintage telephoto lens from the 1970s, built by Tokina or Sun Optical. It features all-metal construction, a tripod collar, and M42 mount, weighing ~870g. Optical design is 5 elements in 4 groups with coated optics; the 15-blade aperture produces pleasing bokeh. Sharpness is modest, with contrast and color acceptable for its age. Handling requires stop-down metering and manual focus, aided by focus peaking on mirrorless cameras. It suits photographers seeking an affordable, characterful vintage lens for casual use.
