Canon built the body of the EOS-1V to deliver top performance regardless of the shooting environment. The strongest available body materials for both functional attractiveness and high-level rigidity were sought out. The magnesium alloy used for the EOS-1VHS is lightweight, yet possesses exceptional strength.
Modern materials
Top priority was placed on the precise machining of all parts. The aperture and hybrid framework structure are diecast aluminum, with glass-fibre reinforced polycarbonate resin, equal in strength to metal. The main outside covers are made of magnesium alloy. The lightweight body benefits from remarkably improved rigidity, precision, and durability, achieved through the use of carefully chosen high-tech materials.
Carefully sealed
The 72 major body seams and moving parts, such as the shutter button, selector buttons and Main/Quick Control Dials, are carefully sealed with silicone rubber, and the edges of the back cover are thoroughly finished. The battery chamber located inside the grip GR-E2 is also 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.
Rotary magnet shutter
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 fibre and super-duralumin, for high reliability in all shooting conditions over extended use. In-house testing has confirmed that the unit is capable of in excess of 150,000 shutter-cycles. The unit performs high-speed shutter operation with exceptional accuracy at a maximum shutter speed of 1/8,000 second and a maximum flash sync speed of 1/250 second.
Low battery consumption
Battery power consumption is minimized because the unit requires no power to hold the second shutter curtain open during bulb exposure. Accordingly, it realizes up to 1,000 hours of operation with the 2CR5 battery at room temperature. |
