- I think the screen with MF aid that you talk about is the microprism screen.
- Can you point out some evidence that this screen messes up the metering
- system? According to the Nikon Handbook published by HP publisher,
- there are three screens available to the 8008. The reason that there
- are only three screens available to the 8008 is because the light meter
- resides in the viewfinder and the focusing screens will affect the
- light meters. The F3 has much more screens available, because the
- meter resides at the bottom of the camera. The F4 has a lot of
- screens available, because there is an adjustment available in the finder
- (at least the standard finder). I suppose that three screens available
- to the 8008 should give very close exposure results (at least my 2020 does).
