Overview

The Praktica 135mm f/2.8 lens, often rebadged as Pentacon, is a vintage M42 manual-focus telephoto known for sharpness and smooth focus. It produces pleasant bokeh, especially at wider apertures, though not the extreme 'monster of bokeh' of the 15-blade version. Build quality is solid, but it lacks autofocus and electronic communication. Optically, it is sharp but not exceptional; some note inconsistent sharpness across distances. It suits portrait and creative photography on a budget, offering good value for those comfortable with manual operation.
