The Canon EOS 1N is a professional 35mm film SLR camera that was introduced by Canon in 1994. It is the successor to the EOS 1 and offers improved autofocus performance and advanced features. The EOS-1N was a revision of the EOS-1, with five autofocus points spread across the frame rather than a single centrally mounted autofocus point, plus more effective weather sealing, a wider exposure range, and numerous other improvements. The camera featured polycarbonate external construction with weather-resistant seals around buttons, dials, and its Canon EF lens mount.
