Wireless connection:

We liked to be “wired”, that is connected to the world around us; but we don’t like wires hanging around! That is the reason why wireless technology is so hot today. Camera manufacturers too, understand the importance of this technology and the benefits it provides. New cameras notably those from Sony, Samsung, Canon and Nikon come equipped with Wi-Fi interfaces. These interfaces are either built into the camera itself or are available as optional modules (example – The Nikon WU-1a Module for the D3200 D-SLR, WT-5A for the D4). Most of the cameras support only image transfer to smartphone through Wi-Fi. This is done through a Wi-Fi hot spot or a direct wireless connection to the smartphone. Once the image is transferred to your phone you can display it, E-mail it as an attachment, or upload it to a site like Flickr, Facebook, etc. This functionality can even be added to most cameras that use an SD card for recording images. This is done simply by using a Wi-Fi card like the Eye-Fi or a Wi-Fi Sandisk card in the SD card slot of your camera. ( For more details see SmartPhotography, April 2011issue). Some cameras allow much more sophisticated operations ( like the Samsung WB150F, the Nikon D3200 + WU-1a). With these you can see on your smartphone screen what your camera sees through live-view

Plus, you can release the shutter too from your phone. If your camera has a Wi-Fi interface built in or supports an optional Wi-Fi module, check out the extent of the Wi-Fi support.
