Sony Alpha ILCE-7SM3 Full-Frame Mirrorless Camera Body

Imagination in Motion

Taking the S series to a whole new level of full-frame movie expression, spectacular new speed combines with supreme sensitivity and ultra-low noise to put previously impossible 4K movie shoots on the menu, with high dynamic range, breathtaking focusing, and extra-strong image stabilisation. Your new creative potential awaits.

For visual trailblazers

With extreme full-frame movie performance including high sensitivity (expanded ISO up to 409600), 15-stop wide dynamic range, 4K 120p2, fast and dependable autofocusing, and extra-strong image stabilisation, the α7S III again raises the bar for movie makers.

New image sensor with double the readout speed

The newly developed back-illuminated full-frame Exmor RTM CMOS sensor, with 12.1 effective megapixels, boasts a readout speed up to twice as fast as that of the alpha 7S II, along with high sensitivity and wide dynamic range

New image-processing engine with up to 8x the processing performance

The BIONZ XR image-processing engine boasts a performance level up to eight times that of the previous processor, minimizing latency while markedly improving real-time processing capabilities for both movies and stills.

High sensitivity, wide dynamic range

The standard ISO range is 80–102400, which is further expandable to 40–409600 (80–409600 for movies). The dynamic range is an impressively wide 15 stops, for beautiful, true-to-life images without blown highlights. Together, the camera's high sensitivity and wide dynamic range expand your creative freedom during shoots.

Full-frame 4K recording at 120p

Full-frame 4K recording at 120 fps16 with autofocus is possible thanks to the high-speed readout capabilities of the new image sensor working in tandem with the newly developed, powerful BIONZ XR processor.This high image-quality 4K, with full-pixel readout without binning, allows for clear post-produced slow motion (up to 5x slower than real time), as well as bokeh effects typical of full-frame cameras, all with smooth, high-precision autofocus.

Recording movies with 10-bit depth and 4:2:2 colour sampling

The camera is capable of performing 4K internal recording with 10-bit depth and 4:2:2 colour sampling when using either Long GOP or All Intra compression. This makes it possible to push your colour grades further, stretching video out for ultimate HDR realism while still retaining natural gradation, for true editing freedom.

16-bit RAW data output

Facilitating improved image quality and more flexible and efficient editing in post-production, the camera supports 16-bit RAW data output to an external recorder via HDMI, for the first time in the alpha series.

Game-changing tracking features to revolutionise movie shooting

Real-time Tracking and Real-time Eye AF make movie-making much easier. Touch Tracking initiates subject tracking with an intuitive touch to the LCD monitor, processing data on colour, pattern (brightness), distance (depth) and facial information to keep your subject in steady focus.

Designed for smooth movie-making

Flexibility in positioning the camera and framing shots is provided by the side-opening, vari-angle monitor, which incorporates a bright 3.0-type, 1.44 million-dot13 LCD screen. The MOVIE button is within easy reach on the camera's top panel, and a durable HDMI Type-A terminal ensures reliable connections to external monitors.
