There's a new device on the market called triggertrap that plugs into our Nikon cameras--most DSLRs are included. <Triggertrap.com> Triggertrap is a device that allows you to shoot from your smart-phone. What I am unsure of is: (1) can you see through your iPhone or Android phone to use it as a viewfinder, (2) can this be used instead of the eye-fi to get the pictures from the camera into the smart-phone?
Any clues anyone?
