Canon eos rebel k2 or Nikon Fm10?

And are these both film cameras?

Yes, they are both film cameras. The Rebel is an autofocus, auto everything else, low end, plastic body, consumer model. The FM-10 is best compared to a tank, a manual body with some auto features, and uses manual focus lenses.

Of the 2, the FM-10 is vastly superior.

You already asked this question, and people already told you the answer (they are film cameras)
