Here is the new Sony a7ii with a 5-axis SteadyShot Inside, which means that the sensor can compensate for movement in the pitch, yaw, roll, x-axis, and y-axis. The technology comes from Olympus which Sony has an alliance with after a large investment. The a7ii is about $500 more than the standard a7. The a7ii will be available next month.
Above shows the added customizable button next to the shutter. There are now 4 customizable buttons instead of 3 on the a7, a7r, and a7s. The body panels of the a7ii looks to be textured compared to the smooth body of the previous a7 cameras. The shutter button moves from the top plate to the grip. The front and rear wheel have a slimmer form factor. There is now a 45° ledge for the Menu and C button on the rear.
