SONY - Alpha 7 IV Full-Frame Hybrid Camera (Body Only)
With groundbreaking performance in both still and movie recording, the a7 IV is the ideal hybrid, providing breathtaking imagery along with connectivity for on-the-spot delivery and distribution. The a7 IV is a camera designed to bring to life the artistic visions of today's creators.
The latest sensor, processing engine, and AI-based autofocus work in tandem with cutting-edge still-photography and moviemaking technology to create a fresh, dynamic imaging experience. The a7 IV is the ideal hybrid, providing breathtaking still and movie imagery, along with flexible connectivity for on-the-spot transmission of your images.
Vari-angle LCD monitor for greater freedom when shooting
The large, side-opening 3.0-type 1.03-megadot touch-panel LCD monitor offers ample brightness for clear viewing in outdoor settings, and its 3:2 aspect ratio makes efficient use of the display area. The vari-angle mechanism allows flexible positioning and framing for handheld shots, gimbal-mounted or documentary-style self-shooting, or very low ground-level shots.
Instant real-time live streaming via USB connection
Live streaming is as easy as connecting to a computer through a USB connection, and you can choose from four different output formats, including high-resolution 4K video. You can select whichever configuration is best for current network conditions and the devices used, and simultaneous internal recording is also available, giving you broad flexibility to cover a wide variety of needs.
Dual media slots, with CFexpress Type A support
Dual media slots allow you to continue shooting even if one memory card fills up. One of the slots supports high-performance CFexpress Type A cards, and both slots support UHS-I and UHS-II SDXC/SDHC cards. With their fast write speeds, CFexpress Type A cards are particularly suited to high-speed continuous still shooting as well as high-resolution, high-bitrate 4K movie recording.
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 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 8x processing speed
The BIONZ XR engine, also used in the flagship a1 and a7S 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 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.
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.
Optical 5-axis in-body image stabilisation for 5.5-step compensation
The a7 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.
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 control through touch operation
Touch Tracking lets you select a subject to track simply by touching the LCD screen, even while using the viewfinder, for more intuitive AF control for both still shots and movies. Easier focus operation is particularly helpful when you're shooting movies alone or using a gimbal, allowing you to concentrate on composing your shots.
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.
Breathing Compensation for consistent angle of view when focusing
For the first time in the a series, the a7 IV provides compensation for focus breathing. Focus breathing is any change in a lens's angle of view that corresponds to changes in focus. Sony's original Clear Image Zoom technology is used to automatically maintain a consistent angle of view, for more movie-like focus transitions. This feature can be used in conjunction with Active Mode image stabilisation to shoot stable, consistent imagery.
