12.2MP full-frame sensor for low light & wide dynamic range
The innovative a7S II features a 12.2 effective MP full-frame Exmor CMOS sensor paired with a powerful BIONZ X image processor, allowing it to shoot at a sensitivity range of ISO 50 - 409600 with unprecedented dynamic range. The extra-large pixels on the a7S II collects dramatically more light than traditional cameras to produce beautifully detailed low-noise images in even the most challenging lighting situations.

World's first Full-frame 4K movie recording with fu ll pixel readout and no pixel binning
The a7S II is the world's first camera to offer internal 4K movie recording in the full-frame format with full pixel readout and no line skipping or pixel binning - resulting in images that exhibit higher resolution and less moiré and jaggies than typical 4K movies.

It also provides you the option of shooting 4k in the super 35mm format and the ability to capture uncompressed 4:2:2 Full HD or 4K QFHD output via HDMI to optional 3rd party external recorders. Enjoy the improved autofocus with 169 AF points and let every lens benefit from the 5-axis SteadyShot INSIDE image stabilization.

Fast precise focusing in light as low as EV -4 with 169-point AF
The a7S II has been upgraded from the a7S and now offers 169 AF points for fast, precise focusing with greater accuracy compared to the original a7S. The low signal-to-noise ratio produced by the image sensor of the a7S II enables the Fast Intelligent AF to detect contrast more easily and react speedily even in low-light situations (as low as EV-4), when it's even tough to check focus with the naked eye. The AF performance on the a7S II is also twice as fast as the a7S during video shooting.

5-axis in-body image stabilization benefits every lens
The 5-axis SteadyShot INSIDE is fine-tuned for 4k video capture. It accurately compensates for blur caused by camera shake from five different directions-vertical, horizontal, pitch, yaw and roll-as opposed to only two in previous systems.
The 5-axis image stabilizing system excels during video recording and even compensates for blur caused by the user walking or running.

120P Full HD 1920x1080 high-frame rate video for 5x slow motion
For the first time ever in the Sony a7 camera series, the a7S II can support high frame rate 120fps shooting in full-HD resolution (1920x1080) 100Mbps using the entire full frame sensor. Video can immediately be reviewed on the camera screen and eventually edited into appealing 4x/5x slow motion footage in Full HD (24p/30p) resolution.

Supports Picture Profiles, S-Gamut. Cine/S-Log
The a7S II boasts numerous features, common to Sony's range of professional video cameras that enhance a cinematographer's ability to capture breathtaking video while benefiting their workflow. Video functionality has been enhanced with new picture profile settings; S-Gamut Cine/S-Log and S-Gamut/S-Log, simplifying color correction and delivering wide dynamic range (up to 1300%).

The a7S II even offers impressive 14-stop latitude in the S-Log gamma setting, while also supporting other popular profiles for cinematographers including S-Gamut/S-Log that can adjust settings like gamma, black, level and color adjustment, and can be saved for use in a multi-camera shoot. Other enhancements include the addition of Gamma Display Assist, a new function that allows users to pre-visualize the post-graded video when recording S-Log movies, and the improvement of the Zebra function for even greater control.

2.4-million dot XGA OLED Tru-Finder with ZEISS T* coating
The XGA OLED Tru-Finder in the a7S II has been upgraded with the world's highest viewfinder magnification of 0.78x (roughly 38.5 degrees in diagonal field of view) and shows clear images across the entire display area. The use of ZEISS T* Coating ensures sharp reduction of reflections on the viewfinder. Unlike an optical viewfinder, the OLED Tru-Finder can be used to instantly show how exposure compensation, white balance and other selected settings are affecting the displayed image.

Durable reduced-vibration shutter
The a7S II 's shutter includes a new braking mechanism which cuts mechanical front/rear curtain vibration by about 50%. Additionally, you can use the electronic front curtain shutter mode for even less vibration.

This not only minimizes camera shake that can blur details and also reduces noise. Silent shutter mode eliminates shutter activation entirely for completely silent shooting. The new shutter mechanism on the a7S II is extremely durable having being tested to 500,000 cycles.

Simple connectivity to smartphones via Wi-Fi/NFC.
Thanks to built-in Wi-Fi, you can easily connect to a compatible iOS or Android smartphone or tablet with the free PlayMemories Mobile App. From there you can control your camera, preview and frame using your mobile device and trigger the camera shutter or movie button.

Then instantly transfer a photo or MP4 movie to your device. NFC (Near Field Communication) provides "one-touch connection" convenience to Android smartphones and tablets with NFC. Simply touch devices to connect. Setting up your mobile device is as simple as downloading a free PlayMemories Mobile app.

Personalize your camera with PlayMemories Camera Apps.
Add new features to your a7S II with PlayMemories Camera Apps. Find apps to fit your shooting style - with everything from time lapse, motion shot and more.

Use apps that shoot, share and save photos to your smartphone using Wi-Fi, making it easy to post photos directly to your favorite social media site or backup images to the cloud without connecting to a computer.

Wider lens compatibility
Directly compatible with the growing family of E-mount lenses, the a7S II can also be used with Sony's A-mount and others lens systems with optional adapters. Sony's complete 'a' lens system includes several premium offerings from Carl Zeiss and G Series Lenses.

Sony's E-mount lens system is particularly well-suited for video shooting, with a variety of models containing "movie-friendly" features like smooth focusing, powered zoom control, and silent iris/aperture control.
