"The Weye Feye from French accessory manufacturer XSories is a compact device that connects Nikon and Canon DSLRs without built-in Wi-Fi capabilities to a smartphone for remote controlling and image transfer.
To use the device you need to plug into the camera's USB port and install a dedicated app on your Android or iOS device. You can then control your camera from a distance of up to 80m. In Live View mode you can change settings such as ISO, white balance or aperture, switch between still and video modes, focus manually or with the AF and of course trigger an exposure. In Gallery mode you can view, select and share images on your smartphone or tablet."
Being able to control your camera from a distance, is now accessible while using your Android. Basically your phone will act as the LCD screen to the back of your camera. This small Weye Feye device is portable and can easily be strapped to a tripod. I feel that this would be best for videos or a photo shoot that has a wide range area.
