I have a Nikon FM and I would like to get one of those Nikon semi-soft cases. Which ones fit a Nikon FM with a 50mm lens (not the series E pancake, but the other one)?
Nikon CF-27 is one that was advertised suitable for FM/FE/FM2/FE2 and FM3a.
An older version called CF-7 is suitable for FM/FE.
There's also CF-29, which is supposed to be used with FM/FE with attached MD-12 motor drive.
