F4...
Ai-type Nikkor lenses (including
AI-S) supported:
* manual focusing with electronic rangefinder with maximum aperture faster than f/5.6
* a
mode, m
mode
* matrix, center and spot metering working
(according to f4 lens compatiblity chart)
F5...
from my understanding the F5 doesnt support
AIS lenses like the F4s and the F6. ie,
*you dont get use of the metering system (3d matrix) but center and spot works
*Aperture Priority AE / manual Exposure
- just like if you stuck an
AIS on the D70.
http://www.mir.com.my/rb/photography/hardwares/nikonfmount/f5compatchart.htm has something to say about it.
F6...
AI-type nikkors are supported: (AI-S)
*electronic range finder
(aid in manual focusing)
* A
mode, M
mode
* all metering
modes
- colour matrix - focal length and maximum aperture entered in
(the f6 can store as many as 10 lenses at a time)
- center weighted
- spot - exposure metering is locked to the center focus area
(cannot select other focus areas)
not sure what the D2x has to say... havent seen a manual as yet.
