The Osawa MC 28mm f/2.8 screw mount is a vintage, manual-focus wide-angle prime lens manufactured in Japan during the late 1970s and 1980s. The "screw mount" designation indicates that this variant utilizes the classic M42 thread mount (42mm x 1mm pitch), heavily popularized by brands like Pentax. This universal mount type allows it to be used on vintage screw-mount film cameras or easily adapted to modern digital mirrorless cameras.
