I just purchased a couple of these bodies ( 645n ) and I really like them. The metering on the n is quite nice (dual 6 zone, spot, center weighted). NoAF lenses yet, so no comment on AF speed. However, it does give you focus confirmation with manual focus lenses - which is very nice. It also imprints data on the film (not where your composition would be). The viewdfinder is much brighter than the older 645 manual focus body. You also have a much nicer layout of shutter speed, exposure compensation and auto bracketing. I love this camera!
