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 realise results that you've been aiming for.
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 50-4096001 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 optimises image sensor performance for superior depiction of details in stills and movies throughout all sensitivity ranges. This image processing engine realises image quality of such fine nuance and minimal noise particularly at the mid- to high-sensitivity setting.
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. * 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, 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.
5-axis optical image stabilisation
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 stabilisation 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 A7s
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.
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 customisable button, so it can be turned On and Off more intuitively.
Wi-Fi / NFC simplifies sharing
With Wi-Fi and NFC (Near Field Communication) built in, 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).
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.
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 per cent) 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.
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, colour 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.
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.
