The following quote is from Thom Hogan. I wish Thom had given more specific details on why Galen disliked the camera. I have a Nikon 4 and it does have some neat attributes. It can use just about all Nikon F mount lenses. It uses dials and knobs rather than cryptic menus. It has autofocus, but not state of the art. I believe Thom once characterized the F4 as the best manual film SLR ever built by Nikon. I have an F4s also, but the F4 is much easier to handle. I would love to hear some of your thoughts on this camera. "Galen Rowell bought a Nikon F5 and flew off to Fiji to do a commercial shoot. I also remember his [expletive deleted] comments about the F5 when he got back. From batteries to lens support to controls and configuration, Galen had a long litany of things he didn't like about the F5. He immediately went back to using his F4. A few years later he got his F100. I was with him hiking the Bay Area Ridge Trail with his new F100: it had the early rewind problem that plagued a few early samples. Galen was so upset he was going to abandon the hike and go back to Emeryville to get his F4, so I lent him my (working correctly) F100 and mostly just used my Olympus XA compact. Those two experiences put Galen off of "modern" film bodies for quite some time, especially the F5, which he never really used again. Eventually he came to grips with the F100 and some of the low-end consumer bodies he used on his runs and climbs, but he never fell out of love with his F4. He's not the only one. It was the epitome of Nikon's traditional film SLR designs. Post F4, things got more electronic, more feature-laden, and more like what eventually became the DSLR."
