Who cares? The FM2N saw lots of action as a bomb-proof, battery-independent back-up camera to the F3 system in the 80s. It delivered the goods. All the fuss about
"pro features and pro-level construction" meant more to house-bound amateurs than it did to pros who used, say, an FM2n as a dependable mechanical back-up camera.
It's a bit of a conceit.
You have to have a Nikon F or F2 fall down a mountain; and then keep taking pictures to know the difference
