I am user of Canon 600D normally and my only experience with analog is Konica Minolta Maxxum 70 which is easy to use and pretty similiar to newest dslrs. My friend gave my old Spotmatic F camera without any lenses, but I've got old FED-4 with Industar-61 (???????? ) 52mm f/2.8. I bought adapter (m39-m42) and mounted it to my camera. However, when this lens is mounted the focus ring isn't moving, it stays on infinity and won't move unless i unscrew it. The only thing working is aperture. Are these two things uncompatible or I'm doing something wrong?
Thank you for any answers.
