The EOS-1N is a 35mm single lens reflex (SLR) camera body produced by Canon. It was announced by Canon in 1994, and was the professional model in the range, superseding the original Canon EOS-1. The camera was itself superseded by the EOS-1V in 2000.

Single-lens reflex camera
A single-lens reflex camera (SLR) is a camera that typically uses a mirror and prism system that permits the photographer to view through the lens and see exactly what will be captured. With twin lens reflex and rangefinder cameras, the viewed image could be significantly different from the final image. When the shutter button is pressed on most SLRs, the mirror flips out of the light path, allowing light to pass through to the light receptor and the image to be captured.
