The FM2 syncs at the odd-ball speed of 1/200 second, and the meter doesn't work at that setting. The FM2n is also calibrated for brighter (K2, B2, E2) focusing screens like the FE2. The FM2 is calibrated for the older screens (K, B, E) that were introduced with the FE. It's not a big deal though. I personally can't tell much difference in brightness between my old FM and my FM2n, and even if you can, you can put a newer screen in the old FM2 and compensate by setting the film speed 1/3 stop lower. I have a distinct feeling that I'm forgetting some other little difference that will come to me in the middle of the night tonight . . . . but -- since I can't remember it, it couldn't possibly be important. ;O) They're both great little cameras. -Don
