One of the world's first true electronic HDSLR remote controls it promises real innovation in the field of HDSLR filming by circumventing the need for any physical contact with the camera and lens for focus and other film/photo operations, instead wiring directly into the camera body to use the internal systems to electronically control focus and advanced camera operations and settings. The advantages are obvious: lenses can be swapped easily without extra hardware or adjustment, nothing jolts the camera unexpectedly during focus, one-man camera operation is easier and safer, and control at a distance is as simple as extending the cable between the camera and the remote. The Deluxe Remote's functions are as follows: 3-step, ultra-precise focus speed Fixed or variable focus control modes Customizable focus speed limit Focus Memory settings Live View control Auto Focus control and Auto Focus point selection Live View Digital Zoom control Video recording start/stop Photo shutter release Remote control and camera battery status Customizable focus direction ISO Shutter speed Aperture Color temperature Exposure level The LCD screen on the Deluxe Remote relays general information from the camera, such as battery charge level, white balance temperature and memory card status – especially useful if the camera's on-body screen is inaccessible. The Deluxe Remote Control is ideal for use as one of the hand grips of a SYMPLA rig, where it means that a single camera operator can properly support the weight of the camera and rig to ensure smooth, accurate movement, while also controlling all camera functions, without removing either hand from the rig. Compatible with Canon's EOS 5D Mark ii, EOS 1D Mark iV, EOS 7D, EOS 60D, EOS 600D/Rebel T3i/Kiss x5, EOS 550D/Rebel T2i/Kiss x4 and EOS 500D/Rebel T1i/Kiss x3. The USB connection also permits occasional firmware upgrades.
