Canon built the body of the EOS-1V to deliver top performance regardless of the shooting environment. Top priority was placed on the precise machining of all parts. The aperture and hybrid framework structure which serve as the base for various parts and fittings are diecast aluminum, with glass-fiber reinforced polycarbonate resin, which is 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, realized by the optimum use of carefully chosen high-tech materials.<br><br>- Rugged reliability: Rigid magnesium alloy body covers, outstanding water and dust resistance, enhanced shutter durability.<br>- Superior customization: 20 Custom functions, optional EOS Link software.<br>- Professional features: 45-point area AF, 100% viewfinder, proven EOS-1 control layout, and more.<br>- Large assortment of available interchangeable AF lenses, E-TTL flash system, remote controllers, close-up accessories, and more.
