For photographers who do not want to bump the bee's knees, spook the subject, or receive a stinging rebuke (or worse), Canon's infrared Wireless Controller LC-5 can make compelling close-ups a snap, even from more than one football field away. Working in Macro mode can demand a level of precision & steadiness that goes beyond the tolerances of typical picture taking. Mounting the camera on a sturdy tripod & controlling the camera functions with a remote switch are long-standing methods of minimizing camera shake & vibration. Now, thanks to Canon's new Wireless Controller LC-5, photographers can easily create compelling close-ups from a safe & secure "line-of-sight" distance of up to 330 feet. Far more than a wireless shutter release, this newly enhanced infrared remote provides photographers with the flexibility to control essential camera functions without intruding on the scene. Compatible with Canon EOS 20D, 10D, EOS-1D, EOS-1DS, EOS-1D Mark II, EOS-1DS Mark II, EOS-3, & EOS-1V Easily capture rock-solid macro shots & close-ups from up to 330 feet away One-shot release mode pre-focuses camera & waits for subjects to cross into range Attaches easily to camera's accessory shoe Powered by four AA-sized batteries
