Accurately adjusting the cameras internal clock with the GPS Receiver GP-E2 is easy because it can use the UTC (Universal Coordinated Time) with a margin of error of about ±0.01 second on the EOS 5D Mark III. The margin of error when used with the EOS-1D X is ±0.02 second. Event photographers will find the transmitter's GPS Time Sync Function quite helpful because it can set and synchronize the internal clocks in multiple cameras. This function is not available when using the GP-E2 with the EOS 7D.
*The EOS 5D Mark III and EOS 7D require a firmware upgrade to be compatible with the GPS Receiver GP-E2, which will be available soon. †When the EOS 7D is used with the GP-E2 the following restrictions will apply: a) geotagging function will not work for movies while recording; b) geotagging features will not work for movies when using the Map Utility; c) electronic compass information and automatic time setting is not available; d) transmission via the hot shoe is not possible.
