If you're like me, I have no straps mounted on my camera. Not always ideal, so here's something a friend showed me. This is a Calumet Aircell Neoprene quick strap. Not only comfortable, flexible, and padded, but it allows you to quickly remove the strap when it's not needed. A good thing for people who want to use Shoulder Rigs, Sliders, Cranes, Steadicam / Glidecam stuff since it can easily throw off the balance. Or people who move from doing Photography to Video. Can be found via Calumet's website (here).
