Today I started to repair one old Prakticar Pentacon 50mm f / 1.8 lens. The camera’s exposure meter could not transfer the aperture value from the lens. It wasn’t the type of glitch that would make it impossible to use the lens, but I like it when things work 100%. After disassembly, a broken plastic of the contacts and a torn resistance path wire were found. A little tin and a melting gun solved it all. Black and white images are taken today after the repair and functionality test.
