Among what is covered is the "12" fps mode (which fixes the camera's aperture but let's ISO and Shutter speed vary to capture correct exposure while maintaining speed) as well as the new locking focus variable flexible spot mode.

Although Sony stresses that the A77 II shouldn't be compared to pro-grade cameras because it's much less expensive, it is starting to gain the kinds of specifications that - at least on paper - suggest it could be capable of punching considerably above its weight. For instance, the improvements to the A77 II's autofocus system extend a long way beyond the focus sensor itself.

The Mark II gains a range of subject identifying technologies that Sony has introduced in recent models. As such, it offers Eye-AF, rather than just face detection. It also gains the most advanced version of 'Lock-On AF' that we've yet seen, which will allow you to specify an off-center starting AF point. Previously most Sony's assumed your subject was the thing at the center of the frame, when you started tracking.
