With a CIPA standard capacity of 410 shots using the EVF, it provides less than half the shooting capacity of the A99's rivals; a direct consequence of having to support full-time live view.

In addition to the complete set of essential features for a pro camera, the A99V has a couple of unique features for this class, including built-in GPS (which strains the already lackluster battery life a bit), in-camera image stabilization (both Canon and Nikon use lens-based IS), and a built-in stereo microphone (which is nice to have in a pinch).
