All Nikkors will work with the EM except the few super-wide/fisheye
lenses that require miror lock-up to fit, though "non-AI" lenses will require a $30 modification before being mounted (non-AI lenses have
a smooth, non-ridged rear edge on the aperture ring - and it can
damage the AI meter tab on the body if you attempt to put it on most
AI bodies). The FG-20 and FG were based on the same body, and the
FG has some nice additional features (TTL flash, M and P exposure
modes are the most important), though the VF screens are not interchangeable, and there is no DOF preview control.
Hope This Helps
