Canon's GPS Receiver GP-E2 records GPS information like longitude, latitude, elevation, direction and Universal Coordinated Time (UTC) as EXIF data on photo files using a compatible EOS camera. This lightweight, compact unit can also serve as an electronic compass or a stand-alone GPS recorder. It was designed specifically for the EOS system, and offers USB and hot-shoe connections with the EOS 5D Mark III and the EOS-1D X (USB connection-only with the EOS 7D).
The GP-E2 offers the same level of dust- and weather-resistance as the EOS 5D Mark III camera when connected to the camera's hot-shoe. Dust- and weather-resistance decreases when it's connected to the camera via the USB cable. For simple and accurate recording of time and location information, the GP-E2 is an ideal complement to the EOS System.
Note: 5D Mark III must be at least at firmware version 1.1.2 to be compatible with this item. 7D cameras must be using at least firmware 2.0.
