FED 28mm f4.5 focusing accuracy

[Dez]

I have recently bought, but have not yet received, one of these rather scarce lenses for my nice old FED-C. When I bought the camera, it came with both the 50mm f2 and 100mm f6.3 lenses, neither of which focuses quite right on a standard LTM body, but seem just fine on that particular FED-C. I know the focus mount wasn't standardized on these cameras, and I am wondering if I will have to fiddle the focus mount on the 28, or will its great depth of field make it unnecessary? It would be a chore to do, since I cannot get at the focal plane of the camera. I guess I could try to get it the same amount wrong as the others on a removable-back Canon, but that seems like a non-extraordinary bodge, so not in fitting with my motto.


Cheers,
Dez
