ePhotoZine have a review of an intriguing device called the Pocket Wizard, which allows you to remotely control your camera.

“Have you ever fancied being able to fire your camera remotely while sat somewhere more comfortable?  I mean you paid all that money for a camera, the least you can expect is for it to do some of the hard work for you.  After hearing stories from other sports photographers and reading lots of good information about the Pocket Wizard system I thought it was about time I gave them a try.”
