<p>Satechi has just started shipping the new Smart Trigger, a US$44.99 Bluetooth add-on that makes it simple to turn your iOS device into a timer remote for your DSLR. Design</p><p>The Smart Trigger comes in five different versions, all of which work with a specific set of DSLRs. For my test, I was using a Canon EOS Rebel T4i camera, which used the "C" variant of the device. Strangely enough, there's nothing on the outside of the box that indicates exactly what camera it's supposed to work with...</p><p>The device includes a small receiver powered by a pair of AAA batteries that sits in the hot shoe mount on your camera. A coiled connecting cable (two different ones were included) is plugged into the receiver on one end and the camera's remote port on the other end.</p><p>There's a free accompanying app -- Satechi includes a QR code on the product box, which assumes that every iOS user with a DSLR also has a QR code reading app on their device. Note to Apple: when are you going to build in a QR code reading capability for iOS? Fortunately, it's easy to search for Smart Trigger in the App Store to download the app.</p><p><a href="http://www.tuaw.com/2013/03/19/satechi-smart-trigger-ios-compatible-dslr-timer-remote/">Keep reading...</a></p>
