Sony Alpha a7S II Full-Frame Mirrorless Digital Camera Body

Exmor CMOS for extra sensor perception

Capture stills and movies of richer, more natural gradation. The 35 mm 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.

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 realizes image quality of such fine nuance and minimal noise, particularly at the mid- to high-sensitivity setting.

Extreme sensitivity, wide dynamic range

With sensitivity settings that can extend up to ISO 409600 plus extra-wide dynamic range, the α7S 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 to realize results that you've been aiming for.

Internal 4K movie recording and XAVC S format 8

The α7S 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 100 Mbps, for highly detailed footage with less impact from compression noise. Internal recording and HDMI output, both at 4K resolution, are available in full-frame format.

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 α7S II solidly supports professional workflow, giving you greater latitude to produce more moving visions than ever before.

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 colour grading, correction and handling is easy. S-Log3 gamma tonal reproduction is better from shadow to mid-tone (18% grey). The camera's 14-stop latitude in S-Log3 setting is impressive. S-Gamut3.Cine reproduces the wide colour gamut of DCI-P3 colour space. S-Gamut3 reproduces almost all actual colours suitable for archiving.

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.

120fps Full HD and 4x/5x slow motion recording

Featuring full pixel readout without pixel binning, 120fps (100fps) capability and ultra-high sensitivity, the α7S 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.

5-axis optical image stabilization

Equivalent to using a 4.5-stop 10 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.

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 α7S.

Wi-Fi/NFC simplifies sharing

With Wi-Fi and NFC (Near Field Communication) built into the α7S 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 favourite SNS (social networking site).

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. Use of the electronic front curtain cuts vibration even more.

Tough magnesium alloy body

Designed for solid reliability and steady handling, the α7S II's compact body is built to withstand the rigours of shooting in the field, thanks to an internal structure and top, front, and rear covers all made of strong, rigid magnesium alloy.

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.
