Why to buy Sony Alpha a7 IV Full-Frame Hybrid Camera with 28-70mm Zoom Lens :
Beyond basic. For a new generation of imagemakers.
With groundbreaking performance in both still and movie recording, the α7 IV is the ideal hybrid, providing breathtaking imagery along with on-the-spot delivery and distribution. The α7 IV is a camera designed to bring to life the artistic visions of today's creators.
Basic has never been this good
Prepare to be inspired. The α7 IV's true-to-life resolution and remarkable AI-powered autofocus complement a range of world-class features at the cutting edge of imaging technology.
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 α1 and α7S 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.
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 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.
4K 60p recording, 4:2:2 10-bit recording
The α7 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.
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.
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-step 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.
Buffer memory supports continuous shooting and recording
Both the mechanical and electronic shutters allow continuous shooting at up to 10 fps with AF/AE tracking. The latest powerful processing engine and increased buffer memory allow faster writing to memory cards, so you can shoot more than 800 uncompressed RAW+JPEG frames (more than 1600 altogether), or more than 1000 compressed RAW+JPEG frames (more than 2000 altogether, up to a full memory card). Increased processing power also allows you to change menu settings even while data is being written to the memory card.
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.
3.68 megadot high-definition Quad-VGA OLED viewfinder
The α7 IV's Quad-VGA OLED viewfinder provides roughly 1.6 times the resolution of the α7 III viewfinder, with a 37.3° FOV and a 23mm high eyepoint. With high resolution, improved electronic viewfinder image quality, and fogging and dust resistance (including significantly improved internal fogging resistance relative to the α7 III), it is designed for clear and comfortable viewing in a wide range of shooting environments.
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.
