Canon EOS 6D review
The Canon EOS 6D us the first DSLR to feature built-in Wi-Fi, and it has a transmission range of up to 30m. There are six separate functions: image transfer between cameras; EOS Utility remote control via a computer; printing from a Wi-Fi-enabled printer; uploading to the online Canon Image Gateway; viewing on DLNA devices; connecting to a smartphone. This last option is particularly helpful and opens up the camera to new uses. It works via Canon's EOS Remote app, which is available for Apple iOS (5.0 or later) or Android OSs (2.3.3 or later) smartphones. Other smart devices, including tablets, will no doubt be made compatible in the future.
Once the smartphone and camera are synced using the app, images stored on the camera's memory card can be viewed and shared via email or uploaded to the phone's image reel. Remote shooting is also possible, with the level of control as good as I have seen, and it is addictively fun to use. The usual touch control of the shutter and autofocus is possible, but exposure adjustments can be made via the touch panel, too, according to the setting on the camera's shooting-mode dial. Furthermore, live view can be controlled, and when it is activated the phone becomes a live view remote. This is particularly useful for wildlife shots and family group photos.
What is crucial to the effectiveness of remote shooting and control is a rapid response time, and the EOS 6D reacts almost instantly to changes made on the smart device. All in all, then, a scene can be viewed and captured accurately through EOS Remote, which is very impressive given that this is Canon's first DSLR with built-in GPS.
