December 2011 Canon's 18.1 Megapixel EOS-1D X DSLR incorporates a number of key internal features including new mirror and shutter units, plus an improved sensor cleaning system. The fourth of a series of six films about the capabilities of the EOS-1D X examines the camera's internal mechanisms and explains the benefits of its control layout. In the film Canon Europe's European Professional Imaging Communications Manager, Mike Owen, explains some of the key internal mechanics of the EOS-1D X. He reveals: "We've been able to achieve the 12fps by putting in a new mirror mechanism that powers the mirror both upwards and downwards, which means it has a lot more control and a lot less mirror bounce." Amongst the key benefits of the new mirror mechanism is that it much more responsive; this helps to enable shorter shutter lag times, with a 50ms standard shutter lag and a lag of 36ms possible via a 'Shortened Release Lag' Custom Function. The shutter unit of the EOS-1D X has a durability of up to 400000 cycles -- this compares to the EOS-1D Mark IV's durability of 300000 shutter cycles. In a first for an EOS DSLR the EOS-1D X features a built-in, Gigabit Ethernet port on the side of the camera for higher speed data transfer. The five features of the wired LAN connection are: FTP Transfer, EOS Utility, WFT Server, Media Server and Time sync. The EOS-1D X has a new sensor cleaning system -- known as Ultrasonic Wave Motion Cleaning (UWMC) -- that, instead of shaking dust particles ...
