Chainfire one of the most talented developers around over at XDA developer forums has released a new app dubbed DSLR Controller. As the name suggests, the app allows users to control their DSLR directly from their Android handset and/or tablet.

Below is a video of the DSLR Controller app in action :

Here is the full list of features which the app packs :

- Live View
- Auto Focus (tap Live View)
- Manual focus adjustments in Auto Focus mode
- Histogram
- Zoom control
- Grid display
- Bulb capture
- Continuous capture
- Extensive modification of settings
— Shutter speed
— Aperture
— Exposure Compensation and Bracket
— Flash Compensation
— ISO speed
— Auto-Focus Mode
— Focus and Zoom area (tap-and-hold Live View)
— Picture Style
— Drive Mode
— White Balance
— Color Temperature
— Auto-Lighting Optimizer
— Metering Mode

How is this even possible, you ask? Well, this app makes use of the USB O-T-G feature found on the latest Android Honeycomb based Tablets. At the moment, there is only one Android phone which supports USB O-T-G and that is the beastly Samsung Galaxy S II. There is another catch, only Canon’s EOS series of DSLR are supported. However, with time, I am sure the app will be compatible with DSLRs of various brands. For the former problem, I expect the next version of Android (Ice Cream Sandwich) to have USB host capabilities.

The app is already available in the Android Market for download, for a whopping €5.99. Since the app is a very early phase of testing, users should keep in mind some bugs and crashes are to be expected.
