Extreme sensitivity, wide dynamic range:
With sensitivity settings that can extend up to ISO 409600 plus extra-wide dynamic range, the A7S II can record images in spectacular and subtle detail, from shadows to highlights, under virtually any lighting conditions. The remarkable clarity and lack of noise in stills and movies that you shoot help provide the results that you've been aiming for.
Internal 4K movie recording and XAVC S format:
The A7S II can record 4K (QFHD: 3840 x 2160) movies internally in full-frame format. Full pixel readout without pixel binning produces 4K movies with less moiré and jaggies. Support for XAVC S format enables 4K recording at maximum of 100Mbps, for highly detailed footage with less impact from compression noise.
0.78x magnification XGA OLED Tru-Finder:
With the world's highest magnification and ZEISS T* Coating, this electronic viewfinder delivers stunning clarity and contrast with minimal reflection and instantly shows how exposure compensation, white balance, and other settings affect images. You can also use Gamma Display Assist and Zebra functions while shooting movies using the viewfinder.
Supports 14-bit uncompressed RAW format:
New compatibility with 14-bit uncompressed RAW format lets you choose the optimal format for your needs. The camera thereby ensures supreme quality of tonal gradation to maximize the benefit of the image sensor's wide dynamic range.
Supported in Capture One Express (for Sony):
Capture One Express (for Sony) is one of the world's best RAW converters, rendering precise colors and incredible detail. It contains flexible digital asset management, all the essential adjustment tools and fast, responsive performance in one customizable and integrated solution.
Enhanced Zebra function:
This function makes it easier to monitor exposure, especially when shooting in S-Log gamma setting. Select a video signal level target from 0 to 109, apply a range to it, then the zebra pattern indicates image areas reaching that level or range. The new wider video signal level selection and ability to assign a range simplify exposure adjustment.
Tough magnesium alloy body:
Designed for solid reliability and steady handling, the A7S II's compact body is built to withstand the rigors of shooting in the field, thanks to an internal structure and top, front, and rear covers all made of strong, rigid magnesium alloy.
ISO Auto Minimum Shutter Speed:
Prevent blur in a shot of a moving subject by setting a shutter speed at which ISO sensitivity starts changing when ISO AUTO (while in P or A mode, or in Multi Frame NR) is selected.
Expand Flexible Spot:
Expand Flexible Spot has been added to AF Area selection. If the selected AF point is not positioned on your subject, the A7S II automatically uses AF points surrounding the selected point to support precise focus.
S-Gamut3.Cine/S-Log3, and S-Gamut3/S-Log3:
With these new profiles, dynamic range can be widened up to 1300% for smoother gradations, and color grading, correction, and handling is easy. S-Log3 gamma tonal reproduction is better from shadow to mid-tone (18% gray). The camera's 14-stop latitude in S-Log3 setting is impressive. S-Gamut3.Cine reproduces the wide color gamut of DCI-P3 color space. S-Gamut3 reproduces almost all actual colors suitable for archiving.
Focus Magnifier & Peaking function:
You can clearly magnify the image to simplify manual fine-tuning of the focus whether shooting still images or movies. The Peaking function can also be activated to colorize the most sharply focused areas of your image for quick confirmation.
Power supply via USB:
The A7S II can be powered via USB connection to a PC or mobile battery. This conserves the camera's battery, allowing you extended operation without worrying that the battery will run out. When the camera is turned off, the same USB connection can be used to charge the battery.
Exmor CMOS for extra sensor perception:
Capture stills and movies of richer, more natural gradation. The 35mm full-frame 12.2-megapixel image sensor achieves wide dynamic range with very low noise throughout a vast ISO 50-409600 sensitivity span. Large pixels, gapless on-chip lens structure, and other light capture advances allow use of extra-high shutter speeds for low-light shooting.
5-axis optical image stabilization:
Equivalent to using a 4.5-stop faster shutter speed, this system is effective at compensating for five types of camera shake. The camera integrates extraordinary image stabilization and sensitivity to light to let you use a greater range of shutter speed/ISO/aperture settings to express what you aim to capture in handheld stills or movies.
Silent Shooting mode lets you mute shutter sound whenever noiseless operation is required, such as when shooting wildlife or concert photos. This function can be used with 5fps continuous shooting, so you needn't miss a crucial moment, and can be assigned to a customizable button, so it can be turned On and Off more intuitively.
120fps Full HD and 4x/5x slow motion recording:
Featuring full pixel readout without pixel binning, 120fps (100fps) capability and ultra-high sensitivity, the A7S II shoots low-noise, high-frame-rate Full HD movies like no other camera. 120fps (100fps) capability also allows internal recording of 4x/5x slow motion movies with frame rate set at 30p (25p) or 24p.
It's very useful to tailor the look of your movies even before shooting them by adjusting image characteristics via Picture Profile settings for gradation, color adjustment, and detail. Save and recall up to nine profiles (PP1-PP9) of adjusted parameters with other settings, including new ones for S-Gamut3.Cine/S-Log3 and S-Gamut3/S-Log3.
500,000-cycle shutter durability:
The camera's shutter passes the test of high durability and endurance through 500,000 cycles, as a shutter braking mechanism reduces mechanical front/rear curtain vibration by about 50%, minimizing camera shake, image blur, and shutter sound. Using the electronic front curtain cuts vibration even more.
More precise white balance adjustment:
The A7S II offers more white balance adjustment steps (twice as many on the amber-blue axis; four times as many on the green-magenta axis) than the A7S, so you can finely tune white balance with more subtle precision for more natural colors.
Compatibility with wide-ranging mountable lenses:
5-axis image stabilization lets you enjoy unparalleled handheld shooting freedom with more of your favorite mountable lenses. The short flange-back distance in the E-mount A7S II extends compatibility with a range of lenses.
PlayMemories Camera Apps add personal touches:
Sony's application download service lets you add new functions and capabilities to your camera. There are apps for photo and movie effects to enhance and express your creativity, and others to allow your smartphone to function as a camera's remote control, for example.
Smart, speedy BIONZ X image processing engine:
The newly refined image processing algorithm of the BIONZ X optimizes image sensor performance for superior depiction of details in stills and movies throughout all sensitivity ranges. This image processing engine achieves image quality of such fine nuance and minimal noise, particularly at the mid- to high-sensitivity setting.
Movie functions improve professional workflow:
With new functions such as 120fps Full HD recording, 4x/5x slow motion recording and Gamma Display Assist joining enhanced Zebra function, time code/user bit editing and other moviemaking capabilities in its feature set, the A7S II solidly supports professional workflow, giving you greater latitude to produce more moving visions than ever before.
Fast Intelligent AF for levels as low as EV -4:
With 169 AF points (25 contrast-detection points, plus nine central AF points each divided into 16 segments, for a total of 25+(9x16)), this speedy, accurate system ensures subject detection accuracy when shooting stills even under low-visibility conditions with lighting as low as EV -4. Moreover, AF speed for shooting Full HD movies is twice as fast as in the A7S.
Wi-Fi / NFC simplifies sharing:
With Wi-Fi and NFC (Near Field Communication) built into the A7S II, you can instantly transfer a photo or MP4 movie to your NFC-enabled smartphone or tablet simply by touching it with the camera, then easily upload the photo or movie to your favorite SNS (social networking site).
New Gamma Display Assist function:
This new function lets you view images with natural contrast while recording in S-Log gamma setting, converting S-Log2 and S-Log3 into ITU709 (800%) gamma for monitoring images or checking focus while enlarging an image, on the LCD screen or viewfinder.
Clean HDMI output:
This function supports 4K and Full HD and allows uncompressed movie output to an external recorder or monitor. The image can also be recorded in the camera even while signals are output using this function. The included cable protector guards jacks and prevents cables from disengaging accidentally, so you can shoot with greater assurance.
Meticulously crafted controls:
Controls are smoothly crafted for you to operate intuitively and adjust immediately even as you look through the viewfinder. The front and rear dials have been particularly refined and positioned for easier, more efficient handling and turning. Also, a new mode dial locking mechanism prevents inadvertent changes of shooting mode at all times.
Enhanced Eye AF:
Now also available in AF-C focus mode, Eye AF automatically detects and tracks an eye of even a moving subject, for more framing freedom.
This function that boosts image brightness by changing shutter speed, for example, can be assigned to a customizable button for easy access when shooting a starry sky or other dark scene.
Creative Style settings bring out the character of your scene. Simply select any of 13 settings (Vivid, Portrait, etc.) and the camera will adjust image parameters. You can also fine-tune contrast, saturation and sharpness to suit your preference.
Picture Effect (13 modes):
Convert everyday scenes into works of art by applying innovative Picture Effect modes that adjust camera parameters and apply advanced image processing with real-time previews for most effects. You can choose from 13 modes, including Toy Camera, Posterization, HDR Painting, Miniature, Watercolor and Illustration.
