The Sony A99's maximum shutter speed is 30 seconds and there's also a Bulb mode for even longer exposures, which is excellent news if you're seriously interested in night photography.

It does have the same manual focus peaking and a sharp EVF as its big brother, so manual focus is just as fast and easy.

SLT A99		vs	A7

	8.4 read review		8.0 read review	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. SLT A99

	8.3 read review		8.3 read review	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).
