Photography: Camera sensor size difference

Ken Rockwell may not be exactly the most reputable person to rely on but he's pretty much right on the money about that.

Oddly, Nikon manual focus lenses on most Nikon AF cameras are almost useless and provide no metering. These same manual lenses used with these adaptors on Canon EOS cameras provide metering, more function than on most Nikon AF cameras. Strange but true!
