As the OP has his heart set on a F5 and seems to be a Nikon film enthusiast, could it be that he meant that the F5 was the only Nikon film camera with colour matrix metering?

It may be that he never looked at the F6 because it is beyond his means. Asking what his mint F80n is worth tends to suggest that money may be tight.

He has made 5 posts. I am sure we all want him to make more and hope that film remains his chosen medium.

The nature of our collective response could be crucial as to how welcome he feels and how he feels about what help he can expect to receive in the future.
