Hey all,
I developed an Android app that serves you as director's viewfinder.
Having your Android device with you, you can see exact framing of your Pocket camera on location, applying your lenses and boosters. Planning your lens setup has never been easier!
Please check out the app: Play Market
The app has ads in it, though not too nasty. You can always switch to a paid Magic Universal Viewfinder that has no ads, no limits and lots of cameras supported -- like BMCC, BMPC4K, 5D Mark III and 4/3 sensored-cameras.
Enjoy and feel free to give your feedback!
Thanks!
