Canon EOS 1D Mark III User Guide - Page 31

VIII. ROCK SOLID RELIABILITY Improved Body Design and Construction The EOS-1D Mark III retains and refines the beautiful curved surfaces and superb basic layout of the EOS-1 series. Ease of operation and holding comfort have been improved appreciably, as has ease of operation with accessories. The new camera is designed to be easier to understand and more reassuring. The massive strength of its magnesium alloy body and chassis, combined with complete environmental sealing, means that the 1D Mark III stands with its forebears as an instrument worthy of the photographers who risk their lives daily to take pictures. Most of the major body components are arranged in the same way as with the EOS-1D Mark II N. The following major units are new or different: • Self Cleaning Sensor Unit • LCD monitor now 3.0 inches (was 2.5 inches) • To attain 10 fps, two drive motors are incorporated • Extension system terminal is provided for the WFT-E2A Wireless File Transmitter Lower cost has been achieved with a less costly imaging element developed and manu- factured by Canon and by downsizing electronic circuits with smaller boards and higher circuit integration resulting in fewer parts.
