I've been a bit sad about not being able to take pictures with my 35 mm lens on my Fed 2 - the camera has an only 50 mm view-/rangefinder.
The other day I made a finder out of a cheap compact camera viewfinder. I fitted it on a flash-shoe-fitting-something that's made for an unknown purpose but suited my task perfectly.
Now my Fed is wide-angle ready with a large viewfinder originally for a 30 mm Pentax.
