Manfrotto Clamp-On Electronic Remote Control for Canon HDSLR Cameras MVR911ECCN lets you react quickly to changing contexts and creative inspiration. This Manfrotto tripod accessory connects to your Canon HDSLR camera via USB and interfaces with the camera and lens firmware directly in order to control focus operations, live view, record start/stop & shutter release, and more. This tripod accessory promises real innovation in the field of HDSLR filming by circumventing the need for any physical contact between follow-focus equipment and the camera lens, instead wiring directly into the camera body to use the internal focus control systems. The advantages of the Manfrotto Bogen Clamp Electronic Canon HDSLR Camera Remote Control are obvious: lenses can be swapped easily without extra hardware or adjustment, nothing jolts the camera unexpectedly during follow-focus, one-man camera operation is easier, and control at a distance is as simple as extending the cable between the camera and the remote. Manfrotto Bogen has perfectly integrated the remote into the SYMPLA system, fitting comfortably to the spacer element of a SYMPLA Adjustable Handle and allowing fingertip control of key camera functions without moving the hand from the grips, in turn making support more stable and secure. Gain precise, intuitive control over your HDSLR camera with the ManfrottoBogen Clamp On Electronic Canon HDSLR Camera Remote Operator.
