Besides a camera bag, a camera strap is one of the most important accessories for a camera. The strap should be comfortable and secure. Lowepro's camera straps fill those needs. They come with quick release clips to get the strap off of the camera easily if you don't need it.
If you're on the move and the traditional style straps always seem like they're always getting in the way, then check out the Black Rapid straps. They are designed for and by professional photographers. Even if you just want to take your camera to the playground, swim meet, or little league game, the Black Rapid straps will let you carry your camera and still stay mobile to get the shot you want.
