While Sony and Samsung are busy making phones with 4K recording capabilities, one developer has worked its pixel magic to get more from iPhone cameras.Ultrakam is the first iOS app capable of recording 2K film resolution, letting iPhone 5s owners shoot 2240 x 1672 pixel video and output movie-quality footage at the touch of a button. There’s support for the iPhone 5 and 5c, as well as the the iPad mini and iPad with Retina display, but the app is limited to high-definition and 2K at 20fps on “older” devices.
