The Zigview S2 Digital Viewfinder is detachable, so you can set up your camera and still know what you're about to take a picture of while hiding in the bushes. The distance you can remotely activate your camera's shutter depends on the length of cable you buy, and you'll probably want to find a way to cover up the line so your neighbors won't, ah...

Okay, I guess the Zigview S2 isn't only for people looking to take sneaky pictures — the viewfinder also has a motion-sensing feature that allows it to take a picture once movement is detected, which will probably appeal to nature-lovers. The Zigview S2 is said to work with most if not all digital SLR cameras, detects brightness in nine sections of the viewing area, and isn't picky about what type of lens you use.

The Zigview S2 Digital Viewfinder costs around $470 depending on where you shop.
