The best of all worlds, the miracle combination. But, most of all, a great little trick of engineering: a radio remote control for your photo camera which communicates with a small gadget fixed in the flash shoe of your SLR camera and transmitting the image right from the SLR direct AV connector.
Really smart thingy.

It works for Nikon and Canon cameras (two different models, though). You can buy it online from PhotoAddict.
