The F was a groundbreaking camera and historically important. It wasn't the first 35mm SLR, it wasn't the first with an automatic aperture, it wasn't the first with a coupled meter(option), it wasn't the first with a metal focal plane shutter with a maximum speed of 1/1000, and it wasn't the first with an instant return mirror.
To be honest, I was sold on Nikon after watching Michelangelo Antonioni's "Blow-Up" as a senior in high school.
