Sony a7IV ILCE-7M4 is the all-arounder advanced hybrid still and video mirrorless camera, boasting the resolution and AF performance that appeals to photographers and a robust 4K 60p video recording performance for filmmakers and content creators.

Newly developed 33.0MP1 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 colour 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 8x4 processing speed
The BIONZ XR engine, also used in the flagship α1 and α7S III models, provides up to an 8x4 increase in processing speed. The engine concentrates real-time processing of AF, image recognition and image quality adjustment to minimise 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.

Beautiful image rendering with low noise
Visible benefits of the powerful new 33.0MP1 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 colour 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.

Smoother gradation rendering with 10-bit HEIF recording
The α7 IV offers HEIF (High Efficiency Image File) still-image encoding, in addition to conventional RAW and JPEG. Smooth 10-bit gradations provide more realistic reproduction of skies and portrait subjects, and the use of 10-bit depth minimises degradation of image quality when editing. HEIF still images recorded in HLG mode can be played back on a compatible BRAVIA 4K TV, via an HDMI connection, to display images with an extraordinarily wide dynamic range.

Optical 5-axis in-body image stabilisation for 5.5-step11 compensation
The α7 IV's high-precision stabilisation unit and gyro sensors work with stabilisation algorithms to achieve up to 5.5 steps of shutter-speed compensation, to maximise the performance of the camera's 33.0MP sensor. This in-body stabilisation allows effective use with a wide range of lenses. The live monitor view shows the stabilised still image while the shutter button is half-pressed, an especially helpful feature when using a telephoto or macro lens, and it can be used in conjunction with the MF Assist and Focus Magnifier features.

Fast Hybrid AF with improved speed, precision and tracking
Using a combination of phase-detection AF and contrast-detection AF, Fast Hybrid AF focuses precisely even on small subjects or on people posed in front of a nighttime background. A wide, dense AF area covers roughly 94% of the image area for both still and movie shooting with 759 phase-detection points, while the contrast-detection AF system uses 425 points. This vast collection of data is analysed in real time by the latest powerful processing engine to achieve the AF system's impressive results.

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.

AF Assist for seamless transitions to manual focus
The AF Assist function, inherited from the Cinema Line FX6, lets you seamlessly switch to and from manual focus during movie shoots. When this feature has been turned on, rotating the focus ring temporarily switches operation from autofocus to manual focus to allow you to deliberately shift your focus to a different subject.
