Canon EF lenses on Nikon F cameras

Can you use Canon EF lenses on Nikon F cameras? Not with a simple adapter — infinity focus is lost. The Canon EF flange distance is 44.00 mm and Nikon F is 46.50 mm, a difference of -2.50 mm.

Verdict: No infinity focus — the Canon EF flange is 2.5 mm shorter than the body's, so an adapter would need corrective glass.
