50mm · f/1.8
The Pentacon auto 50 mm f/1.8 MC is a compact, all-metal vintage lens with a close focus of 33 cm, praised for its vibrant colors and solid build. Optically, it is soft wide open with noticeable flare and weird bokeh, but sharpens when stopped down. Common issues include stiff or loose focus rings. It is very affordable (often under €30) and easily adapted to modern cameras via M42 mount, suiting photographers seeking a cheap, characterful lens for close-up or artistic work.
