In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line. Carrying an extra camera body just to avoid scrambling for another lens seems a bit silly, no. Quikdraw wants to run that convoluted method out of town with a holster system that lets you carry Canon or Nikon lenses on your belt and change them in around five seconds. The holder start in a locked vertical position, and to attach a lens you just bayonet it into place, securing the glass and allowing the holder to be lowered.
