Uses (and meters with) all my lenses from ais to G lenses with VR, and likely some that are still only on the drawing board.
The auto focus is fast and accurate and the metering is stellar.
It can do wireless remote i-TTL flash and shares batteries with a D-700/MB-D10.
When the F4 was new, I wanted one so badly, but the best I could afford was an 801s (an excellent camera in its own right).
When the chance for a new F6 came along, I wasn't going to pass it up.
Not only 35mm, it has become my favourite camera of any format.
