It has been prefered by many pros in its age.
#EBAY NIKON F6 PRO#
Sometimes things are desirable because they are rare, found only in high end cameras or not at all (no modern SLR or DSLR has mirror lockup, for example). These include mirror lockup (as opposed to pre-release), 1:1 closeup lenses and 100% viewfinders. There are a number of photographic things which seem highly desirable, but not all that useful in practice.
#EBAY NIKON F6 FOR FREE#
I simply can not justify spending $1,600 for a F6 when I got an F5 for free (almost). In my opinion, $1,600 used is too much, but I'm sure it's worth it if you can afford it. The F6 on the other hand (which I have never actually seen in real life) is reportedly the best and most advanced 35mm camera money can buy.
If you want a good comparison, go to a camera store and hold a D300 and a D3, that's about what you are dealing with. A mint F5 on the used market costs about twice as much as a mint F100, and since you are only talking about $500 vs $250 US, it is definitely worth it if you don't mind the weight. That, also coupled with the fact that I was simply drooling over the F5 for some time (and the F6, but I can not justify that cost since I don't normally shoot 35mm). I traded it for two reasons, F5 has mirror up-lock, F100 does not, and the F5 is reported to have better flash exposure (in TTL mode) than the F100. It is heavier than the F100, but it definitely feels like a camera that will never let you down. I traded my F100 and a large format lens (which I would never use again anyway since I replaced it with a much nicer lens) for a mint F5. I have read somewhere that this was an issue with the F100. I had a F100, and it is a fantastic camera, but I did find it difficult to get good exposures with my SB600 flash.
