"When the AE Power Winder FN or AE Motor Drive FN is attached to the New Canon F-1, a choice of shutter-priority AE or manual exposure is available according to the shooting situation and your personal preference."
-So to get shutter priority metering you have to have have a external winder attached??
Wtf is the AE Finder for then if the camera allready has aperture priority but requires the winder for Tv?
The winder on the New F-1 is supplying extra power to the camera to set the aperture automatically with shutter priority AE. The AE Finder FN has the metering control for aperture priority AE. If you have the standard finder, you don't have aperture priority AE.
I have the AE finder and the motor drive, but personally, I've always used spot metering and manual exposure.
