XDA Legend Chainfire, has just posted a pretty cool video on an app that allows you to connect your Android device, in this case a Samsung Galaxy S2 to a very cool DSLR camera, the Cannon EOS 550D. Chainfire takes the EOS USB cable and connects to the SGS2 via a USB On the go cable and demonstrates how you can now have LiveView on your Android device using the Proof-Of-Concept app. The SGS2 device shown was not rooted either so this sounds really interesting.
I reached out to Chainfire for more info and download links so stay tuned. In the mean time, enjoy the video:
