Hi Chris,
Seeing as Nikon comes out with a new F every 9 years on average, we aren't due for one for a couple years yet. Nikon may never introduce another film camera, but other manufacturers have.
if Nikon keeps the old rate, then in 2014 an F7 would be introduced. But I think it is quite unlikely considering yearly production numbers of F6 in the 1000 - 1500 range.
Probably they will continue production of F6 for some years as long as there is demand.
The other reason is: You can't improve the F6. It's the perfect 35mm SLR.
- perfect ergonomics
- perfect metering system
- perfect viewfinder
- excellent AF, extremely precise
- excellent with manuel fokus: better than most pure MF cameras I have used, precise manuel focus by split-image (screen A) and fokus indicator
- all AF- and AI-S / AI Nikkors can be used (and Zeiss ZF of course)
- extremely well dampened shutter and mirror
- data recording with MV-1 (full exif data)
- extremely robust
- excellent flash metering
So honstly, I really don't know any reasons to develop an F7.
There is nothing to improve on the F6.
I do want one, but the price!!! I haven't bought a new camera since I got a D100 in 2002, and it cost less than that with 2 lenses! I'll just need to make do with my "obsolete" F5 for a while.
Strange, when the D100 was introduced in Europe, it had about the same price as the F6.
But in contrast to the D100 the F6 is a lifetime camera: Buy it, enjoy it for the rest of your life and when you have passed your children can use it.
And considering this, it is an extremely cheap camera, worth the price.
Cheers, Jan
