Description — Canon EOS 3
The Canon EOS 3 is a 35mm film SLR built on the Canon EF lens mount, combining advanced autofocus technology with a weather-sealed, professional-grade body. Its 45-point phase detection AF system is complemented by Eye Detection AF and subject tracking, allowing the camera to actively select focus points based on where the photographer is looking through the optical pentaprism viewfinder. Burst shooting reaches 4 frames per second, and the camera accommodates film rated from ISO 6 to ISO 6400.
The body is constructed from a polycarbonate shell over a metal chassis and is fully weather sealed, measuring 161.9 x 119.6 x 70.5mm and weighing 885g. Flash integration covers E-TTL, A-TTL, and TTL modes through the standard ISO hot shoe, with a PC sync socket and 1/200s sync speed also on board. A single 2CR5 lithium battery powers the camera for approximately 50 rolls of 36-exposure film, with an optional PB-E2 grip supporting 8x AA or Ni-MH batteries for extended sessions.
