Originally posted by maltfalc righty tighty, lefty loosey. people are used to twisting things counter-clockwise to remove them, so the nikon lens mount will be counter-intuitive to most people. the release button is in a less convenient spot as well.
Very counter-intuitive, someone gave me an old Nikon film body and a couple lenses, body was junk, lenses weren't anything special but I wanted to modify them for my K100D anyway. At first I thought the release was broken since the body was in such rough shape, grabbed my feeler gauges and poked around and it was definitely releasing, then I realized they did it bass-ackwards.
