I am a big fan of Nikon SLRs, but the Nikon 5 (great camera) is about as light as an anvil. Even the F100 is quite heavy. I am pure amateur and don't do sports so frame rate is not important to me, nor is weather sealing. My picks are the N80 for autofocus lenses, great metering, the FE for non-AI lenses and the FE2 for AI lenses. I consider the Nikkormats as passé and heavy, with unreliable metering.
