Description — Canon EOS 1N
The Canon EOS 1N is a 35mm film SLR designed for serious professional use, built around the Canon EF lens mount and shooting on the full 24x36mm 35mm film frame — a genuine full-frame (1.0x crop factor) format. The autofocus system uses phase detection with 5 selectable focus points, and burst shooting is available at up to 6 frames per second. The camera accommodates an ISO range of 6 to 6400, making it versatile across a wide spectrum of film stocks.
The body is constructed from polycarbonate with weather-resistant seals (rated as Weather Sealed) and weighs 855g, with dimensions of 161 x 112 x 72mm. The optical pentaprism viewfinder provides 100% frame coverage and a dioptric adjustment range of -3 to +1. A top-mounted monochrome LCD panel displays shooting information.
Flash metering is TTL-based, compatible with Canon Speedlite EX and EZ series flashes via the standard ISO hot shoe — note that E-TTL is not supported. Power comes from a 2CR5 lithium battery, with optional BP-E1 and PB-E1 battery pack accessories available for extended sessions.
