Fully electronic mount system
EN: Fully electronic mount system
Development of the EOS system began with Canon s own body range-finding and in-lens motor drive system and fully electronic mount system, technologies that were developed in 1985 to quickly respond to the trend towards full-fledged autofocusing SLR cameras. The EOS system centers on the camera body and consists of various components including Canon s full line of EF lenses, Speedlite flash units, and interchangeable backs. The three main features of the EOS system are as follows. Multi-processor system control A high-speed processor in the camera body interfaces with processors in the lens and the flash units, (for high-speed data processing, calculation and communications), to carry out high level systems control. Multi-actuator system The ideal actuator for each drive unit is located near the drive unit to form a multi-actuator system that realizes high-level automation, high efficiency, and high performance. Fully electronic interface All data transfer between the camera body, lens, flash and interchangeable back is handled electronically. This not only increases the functionality of the current system, but also creates a network ready to accept future system developments.
