Magnesium alloy cover (Front) (back) Durability and reliability It’s not just metal. It’s magnesium alloy. Professional photographers need tools they can depend on in any conditions. Not just ideal conditions. The EOS-1D was engineered from the ground-up for this kind of use. Its body is superb: built of cast magnesium alloy, it combines strength, rigidity and effective magnetic shielding of the electronic components with light weight. It’s been engineered to withstand extremes in temperatures, down to the construction of its autofocus optical system underneath the mirror box. And no professional digital SLR has ever been as effectively protected from dust and the elements as the EOS-1D. “Like the renowned Canon EOS-1v 35mm professional SLR”, the new EOS-1D pro digital SLR is the most extensively-protected camera in its class. Seventy-two points on the camera body are specifically gasketed and sealed to protect it even in the harshest conditions, and the NP-E3 battery pack is gasketed as well Red : Main sealing parts(Front) (back) to protect the battery compartment. Even the lens mount has a protective rubber surface, which mates with rubber gaskets on certain professional EF lenses.
