Presenting the world’s smallest and lightest1 full frame interchangeable lens camera. With a groundbreaking 35mm large pixel image sensor rated at 15.3-stops of dynamic range and an ISO 409,600 sensitivity2, the α7S reveals astonishing detail and color even in the dead of night. Video excels with Full Pixel Readout, a 4K-optimized sensor and uncompressed 4K output. Fast, intelligent autofocus completes the picture.

Full Pixel Read-Out with Clean HDMI Out for 4K Recording

Line-Skipping has been the Achilles Heel of video recording DSLR and Mirrorless cameras since video recording was first introduced. Most full-frame and APS-C still cameras have extremely high pixel counts, which is great for still photography, but makes utilizing the whole sensor technically infeasible when recording video since scaling down, say a 36 megapixel image in real time would require a much more expensive image processor and generate more heat than such a compact body could handle. So traditionally these cameras skip lines when recording video, leading to major aliasing and moiré from the large sample gaps as well as decreased resolution and increased noise. However, the lower resolution sensor of the a7S is designed for video recording and features a full sensor readout without any line skipping. 

Full-Frame Exmor Sensor and BIONZ X Image Processor

Incorporated within the sleek body design is a 12.2MP full-frame Exmor CMOS sensor and BIONZ X image processor, which work together to enable an expansive dynamic range with minimal noise and notable sensitivity. The a7S features a native sensitivity range from ISO 100-102400, which is further expandable to ISO 50-409600. Coupled with the large individual pixel size the 12.2MP sensor affords, this camera is well-suited to use in low-light conditions.

The sensor's design also features a new-generation RGB color filter array, as well as a gapless on-chip lens design. Together, these two technologies enable truly efficient light-gathering abilities that further reinforce the low noise, high-sensitivity design. Furthermore, an anti-reflective coating has also been applied to the seal glass of the image sensor to minimize surface reflections, glare, and ghosting for contrast-rich, color-neutral imagery.

Audio Input & Headphone Jack

The a7S features a 3.5mm microphone input jack for compatibility with external microphones. And for users needing more the a7S is also compatible with the Sony XLR-k1M XLR Adapter for recording professional balanced XLR audio signals with phantom power and adjustable mic/line inputs. 
For monitoring audio the a7S features a 3.5mm headphone jack as well as real time audio levels for a visual reference.

Body Design

Revolving around a compact, sleek body design, the a7S features both a large rear LCD monitor as well as a bright electronic viewfinder. The rear 3.0" 921.6k-dot Xtra Fine LCD features a tilting design (up 90° and down 45°) to benefit working from both high and low angles. Also benefitting visibility with the rear monitor is the incorporation of WhiteMagic technology, which noticeably increases brightness for easier viewing in sunlit conditions. When shooting at eye-level, the 0.5" XGA OLED electronic viewfinder features a high 0.71x magnification and a 2.36 million-dot resolution for precise monitoring capabilities.

Up to 120 fps High Speed Video Recording

In addition to the standard 24p/30p/60i recording formats the a7S is also able to record at much higher frame rates for slow motion playback, albeit at lower resolutions. 1080p video can be recorded in up to 60p using the entire sensor. And 120 fps is possible at 720p using an approximately APS-C sized center crop of the sensor. 120 fps recording allows for about 5x slow motion when played back in 24p.

Customizable Color Profiles and S-Log2 Gamma

To make sure the a7S is able to use its extensive dynamic range while recording video it incorporates extensive customizable color and gamma controls. Users can adjust the gamma, black level, knee, color level, and more. Also users can use the same S-Log2 Gamma Curve that is found on high end Sony Cinema cameras that squeezes up to 1300% more dynamic range into the video signal then traditional REC709, for increased post-production flexibility.

Live Video Overlays

The a7S features many of the same real-time visual overlays and aids that professional video users have come to rely on. These include focus peaking to aid in manual focusing, zebra markers to help judge overexposure, and an audio level overlay for mixing audio. Also focus magnification is available for checking critical focus. These are available in both viewfinder and LCD display.

Built-In Wi-Fi Connectivity with NFC

Built-in Wi-Fi connectivity enables the a7S to instantly share imagery to mobile devices for direct sharing online to social networking, via email, and to cloud storage sites. NFC (Near Field Communication) is also supported, which allows for one-touch connection between the camera and compatible mobile devices; no complex set-up is required. Once connected, the linked mobile device can also display a live view image on its screen and remotely control the camera's shutter.
