Hi Bernard,
Agree 100% with Rob.
I also had an F3 in my student time, it is a fantastic camera. But then I changed it for a FM2, looking for smaler portable gear.
I also agree that I prefered the F3 from the F4 that was a like a russian tank.
Well, you already have a FF Nikon, may I ask you why you felt attracted by the F3 that you can not have with your digital Nikon?
Is it for the touch, ergonomic, or for film like pictures?
Cheers,
Fred.
