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.

As with Live View, continuous phase-detection AF is possible whilst shooting movies on the A99, a distinct advantage over most DSLR cameras and fast enough to rival Compact System Cameras like the Panasonic Lumix GH series.

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).

With the correct white balance selected, the Standard Picture Control setting produces nice vibrant images that are a good match for the scene.
