The Flash Dock from PocketDemo is a great way to unite your iPhone, or any similarly sized smartphone, with your DSLR camera. The case is designed to hold your smartphone and attach to the hotshoe on your camera. This allows you to take advantage of the wide range of photography-related apps out there via your 3G, 4G, wireless or Bluetooth connections.
While the hotshoe is only used for holding the adapter, once attached you can reap the benefits of combining your DSLR and smartphone capabilities. Geotag photos with the same GPX files your smartphone apps use. Share photos through social media channels, text messages or via email. Or even use an app to calculate the light meter reading, depth of field, and level your camera to the horizon.
