The Canon GP-E2 GPS Receiver is a compact, lightweight GPS unit that sits on the hot shoe and makes it easy for photographers to geo-tag their images. A GPS Logger function also allows photographers to track their route by downloading GPS data at regular intervals, whether the unit is attached to the camera body or stored in its case. The GP-E2 is compatible with the EOS-1D X, EOS 7D (via Firmware update - connection via cable only - See our Further Details tab) and new EOS 5D Mark III, the GP-E2 tags photos with longitude, latitude and altitude data as well as the direction in which the shot was taken, adding information to the EXIF file of the image.
