I use the GP-E2 with my new Canon 70D Camera. It can be shoe-mounted, placed in a AB-E1 Bracket attached to the camera (and connected with an interface cord which is provided with the GP-E2), or worn in a pouch on your belt (and connected with a longer interface cable also provided with the GP-E2).
Easy To Use; Improves Functionality; Well Made; Works Well With GPS
