Sony Alpha a7II Mirrorless Body with Pro Kit #ILCE7M2/B B

The Sony a7II is the world's first full-frame camera to feature optical five-axis image stabilization, with Sony claiming a 4.5-stop gain. Featuring a 24.3MP 35mm Exmor CMOS sensor, the camera also boasts several ergonomic improvements and improved AF responsiveness.

Advanced Image Stabilization

The Sony A7 II takes in-camera stabilization to a new level. It is said to offer a 4.5 stops of stabilization thanks to a five-axis IS technology that compensates for yaw and pitch-common when using a telephto lens; roll, which can affect video and night shots; and the most common X- and Y-axis shake. You can easily verify the effectiveness of the stabilization in the viewfinder and LCD monitor in Live View. IS is optimized for every Alpha and E-Mount lens, according to Sony. (The only other cameras to offer five-axis stabilization are made by Olympus for their most recent Micro Four Thirds models.)

Improved Autofocus

Sony claims a 30 percent faster autofocus response (compared to previous Sony a7's), thanks to a more advanced algorithm that's deployed for detecting the subject position. A dual AF system, which is also used in the a7 II's predecessors, consists of a 117-point phase-detection AF sensor, and 25 contrast detection AF points, which Sony has placed over a wide area of the screen. This should improve focus tracking as well as focusing on off-center subjects.

An improved, original Sony algorithm for the prediction o f moving bodies results in a 1.5 times improvement in performance in tracking a subject and predicting its next movement. Additionally, AF and automatic exposure (AE) continue to track the subject during high-speed continuous shooting (up to 5 fps). The a7 II retains its predecessor's Eye AF feature-the camera tracks and focuses on the subject's eye, even when the face is partially turned away.

Ergonomic Refinements

Users can transfer photos or MP4 movie files to Android-based smart phones and tablets via either Wi-Fi or NFC, and users can take advantage of Sony's PlayMemories Camera Apps, which let you expand the camera's functionality.

Carry-Over features

Other than the above changes, the a7 II offers pretty much the same stellar feature set as the a7, including:

1200-zone Evaluative Metering: You can choose from multi-segment, center-weighted or spot metering.

Area-Specific Noise Reduction: The image processing engine selectively divides the image into into areas based on patterns (such as edges, textures and flat areas like blue skies), then applies the most appropriate noise reduction for each area to reduce noise.

Multi-frame noise reduction: The a7 II composites four shots to suppress noise and raise effective sensitivity in low light without a flash, while the D-range Optimizer helps coax details out of shadows and highlights of contrasty scenes in one shot.

16-bit image processing, 14-bit RAW output: 16-bit image processing and 14-bit RAW output help preserve maximum detail and produce images of the highest quality with rich tonal gradations. The 14-bit RAW (Sony ARW) format ensures optimal quality for later image adjustment (via Image Data Converter or other software).

In-camera RAW converter: Lets you adjust exposure, white balance, tonal curves, saturation, contrast, hue, sharpness, or apply D-Range Optimizer or vignetting compensation.

As with the a7S, the A7 II offers XAVC S format video with clean HDMI output and video capture up to 1080 60p. Uncompressed 4:2:2 8-bit output via HDMI into an external recorder is also available. An optional S-Log gamma profile can be added for enhanced dynamic range.
