Two months after expanding its Alpha series for the last time with the Sony Alpha a5100, Sony proudly announced a new member of this class, a successor of the Sony Alpha a7 - Sony Alpha a7 II. The precedent set by this full-frame MILC 24MP camera (maximum resolution 6000 x 4000) is its 5-axis sensor-shift image stabilization, which is the first stabilization of this kind displayed by any full-frame mirrorless camera. Sony states that this image stabilization system (IS) can diminish camera shake by 4.5 stops according to the CIPA standard. If an E-mount lens with Optical Steady Shot (OSS) is mounted on this camera, the camera will recognize it and apply a combination of in-lens and in-body stabilization.
As its predecessor, the a7 II exhibits 117 phase detection points on its CMOS sensor, along with 25 contrast detect points, yet Sony claims that, despite such a situation with focus points, the a7 II's AF speed has been improved by 30%, while tracking performance is 1.5x better than the one of the predecessor. Namely, this enhancement is a consequence of Sony’s 'proprietary image analysis technology', which uses more information from each scene in order to keep focus locked on the target.
From the point of view of the video, the Alpha a7 II is characterized by the XAVC S codec, which provides video recording in Full HD (1080/60p) at 50 Mbps. This model also supports S-Log2 so as to encompass a wide dynamic range.
As far as the design is concerned, the most significant changes in comparison to the predecessor Sony Alpha a7 have to do with the grip, which is larger now, and with the inclusion of a front dial. The shutter release button has been moved to the top side of the grip, which is a more natural position for it, while the front side of the camera is now made of magnesium alloy, in contrast to plastic, as it was the case with the predecessor. What is more, the lens mount has been reinforced, which will ensure greater stability while using heavy lenses.
It is expected that the Sony Alpha a7 II reaches the cost of Japan on December 5, and it will be sold at a price of ¥190,000 ($1,600). As for the availability in other regions of the world, that information is still to be announced.
