33MP Full-Frame Exmor R CMOS Sensor
Up to 10 fps Shooting, ISO 100-51201
759 AF Points (Wide AF Coverage)
10-Bit 4:2:2 , S-Cinetone

Newly developed 33.0MP back-illuminated CMOS image sensor
The full-frame Exmor R CMOS sensor delivers outstanding speed and superb image quality.
The use of copper wiring contributes to higher transmission speeds and faster AD conversion, while fast sensor readout enables 10-bit 4:2:2 4K recording at up to 60p.
The sensor also provides improved color reproducibility, low-noise performance at all sensitivities, 15-stop dynamic range on stills, and increased AF precision and focal stability.

BIONZ XR image processor for up to 8x processing speed
The BIONZ XR engine, also used in the flagship 1 and 7S III models, provides up to an 8x increase in processing speed.
The engine concentrates real-time processing of AF, image recognition, and image quality adjustment to minimize processing latency, for greatly increased movie and still processing power.
User interface, network, and file management processing is distributed in order to deliver fast response regardless of real-time processing load.

4K 60p recording, 4:2:2 10-bit recording
The A7 IV gives you an impressive range of video recording options.
Full pixel readout without binning allows 4K 60p recording, and when recording 4K movies at 30p, full-frame 7K oversampling produces high-resolution, highly detailed 4K. 10-bit 4:2:2 video can be recorded internally, allowing fuller, more natural gradations and greater editing freedom.
The XAVC HS file format provides roughly twice the coding efficiency of MPEG-4 AVC/H.264.

Beautiful colour expression made simple, with S-Cinetone
The A7 IV supports S-Cinetone, based on expertise gained through development of the VENICE CineAlta camera. This look is responsible for the beautiful skin tones for which Cinema Line cameras like the FX9, FX6, and FX3 are widely acclaimed. It delivers natural mid-tones for healthy-looking skin color, plus soft colors and gorgeous highlights. Because it’s in-camera, it’s easy to create a more expressive look for your movie imagery without post-editing.

Beautiful image rendering with low noise
Visible benefits of the powerful new 33.0MP sensor and engine go beyond mere numbers. They include soft, natural-looking human skin textures, a stunning level of detail in landscapes and scenery, and better color reproduction, with higher subjective resolution resulting from improved algorithms. The standard sensitivity range of ISO 100-51200 is expandable to ISO 50-204800 for stills and ISO 100-102400 for movies, with low-noise performance throughout.

Set the mood, in-camera, with Creative Look
Broaden your creative palette with a selection of ten Creative Look presets.
You can easily impart a particular mood in your still images, movies, and live streaming, and all preset selections are available in-camera without post-editing, so you can share your vision immediately after shooting.

Soft Skin Effect for bright and beautiful skin appearance
The built-in Soft Skin Effect makes skin look more beautiful, softening wrinkles, blemishes, and dull patches while preserving liveliness in eye and mouth areas. Complementing the capabilities of the full-frame sensor, this feature can add appeal to live-streamed sessions, as well as enhancing still shots and movies. Four level settings are available, so you can adjust the degree of the effect as you wish.

AI-based Real-time Eye AF and Real-time Tracking
The superior processing power of the BIONZ XR engine has led to improvements in both Real-time Eye AF and Real-time Tracking features.
Improved face detection translates into 30% better eye-detection accuracy, while faster image processing yields higher accuracy when the subject is looking up, down, or sideways.
Real-time Tracking allows you to select your subject and then leave tracking to the camera, relying on the latest subject recognition algorithm and high-speed analysis of spatial data by the processing engine.

FE 28-70mm f/3.5-5.6 OSS Lens
Included with the camera is the versatile wide-angle to portrait-length FE 28-70mm f/3.5-5.6 OSS lens. This lens features one extra-low dispersion element and three aspherical elements to control both chromatic and spherical aberrations throughout the zoom range. A linear autofocus motor, coupled with an internal focusing design, offers quick and quiet focusing performance to suit both stills and video shooting. Additionally, Optical SteadyShot image stabilization minimizes the appearance of camera shake and a weather-sealed design permits working in inclement conditions.
An all-arounder that pushes beyond basic, the Sony Alpha a7 IV does double duty with strong stills and video performance. An advanced hybrid mirrorless camera, the a7 IV has the resolution and AF performance that appeals to photographers along with robust 4K 60p video recording for filmmakers and content creators.
The newly developed 33MP Exmor R CMOS sensor pairs with the BIONZ XR processor from the Alpha 1 to achieve quick shooting up to 10 fps and 4K 60p video recording, along with broad sensitivity up to ISO 51200 and a wide 15+ stop dynamic range. Beyond image quality, the sensor and processor also contribute to an advanced AI-based AF system that supports Real-time Eye AF and Real-time Tracking for intuitive AF control and subject tracking.
