In another thread you say that it is hard to move the focus ring. Can you rotate it from ~0.7 m to infinity ?
What colour is your lens ? Black or silver ?
What is the mount ? M39 or M42 ?
M39 lenses usually had a register of 45.2 mm. If you have such a lens, with an M39-M42 adapter ring, and if you are using an M42-camera adapter you will be unable to focus to infinity. The normal M42 register length is 45.5 mm. _________________ John |
