Canon EOS 1V Camera

In developing EOS-1V as a next-generation professional SLR camera, Canon sought out the strongest available body materials for both functional attractiveness and high-level rigidity. The magnesium alloy used for EOS-1V is lightweight, yet possesses exceptional strength. This new material is hard to machine and was initially thought to be unsuitable for molding the delicate curved surfaces of the EOS body. Canon solved this problem with the application of "thixo-molding", an advanced injection molding technology. Professional cameras must be impervious to sharp changes in temperature; they must also be resistant to water, sand and dust. In other words, the professional camera must work smoothly under a wide range of conditions. EOS-1V has been developed and manufactured to reflect feedback from professional photographers who work in severe environments, as well as Canon's own expertise in this area. Following a reassessment of the severity of conditions that may apply in some shooting situations, Canon has succeeded in raising the level of water and dust resistance. The 72 major body seams and moving parts, such as the shutter button, selector buttons and main and quick control dials, are carefully sealed with silicone rubber, and the edges of the back cover are thoroughly finished. Furthermore, the battery chamber located inside the new grip GR-E2 is protected by packing, while the insides of function buttons, found on the upper left of the body, are protected from dust and water by a silicone rubber boot.

The satisfyingly solid feel and sound of the back cover being closed will tell you that the EOS-1V stands up to the elements like no other camera. The EOS-1V's electronically controlled rotary magnet shutter has been designed to eliminate the possibility of operational trouble. This shutter unit ensures constant operation that remains as accurate as its original performance even after long use and under severe shooting conditions. In this shutter system, the first and second shutter curtains are controlled by a non-contact rotary magnet, which does not suffer sticking problems due to dust accumulation. The shutter blades are made of carbon fiber and super-duralumin, for high reliability in all shooting conditions over extended use. This has been confirmed by in-house testing in which the unit recorded in excess of 150, 000 shutter-cycles. The unit performs high-speed shutter operation with exceptional accuracy.
