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. Easy, reliable operation A brand-new imaging experience  Flagship-quality still and movie imaging Newly developed 33‑MP2 full-frame back-illuminated CMOS image sensor Delivering outstanding performance and excellent image quality in both stills and movies, the α7 IV's new 33.0 megapixel2 Exmor R™ CMOS image sensor provides high-speed readout, high sensitivity, low noise, and highly accurate colour reproduction. 
Flagship-level image processing with BIONZ XR™The α7 IV uses the latest image processor to offer greatly enhanced performance, with improved image quality and colour reproduction. Fast processing speeds facilitate comfortable continuous shooting as well as responsive operation while performing data transfers.Still photography without compromiseHigher resolution, better colour reproductionThe new 33‑MP2 image sensor and processing engine raise the bar for image qualityIn addition to boasting a larger pixel count and higher resolution than the α7 III, the α7 IV and its powerful Exmor R sensor represent a significant evolution of Sony's original image technology, for improvements that go beyond mere numbers. Experience new levels of colour gradation and detail rendering as well as soft, natural-looking human skin textures. Enhanced resolution and colour Low noise Wide dynamic range Quickly set the visual mood with ten Creative Look presets  A selection of ten Creative Look presets and eight parameters can quickly craft a mood for your still images, movies, and live streams. And since no post-editing is needed, you can share your vision immediately after shooting. 10-bit HEIF4 still-image format for smooth gradations  Along with conventional RAW and JPEG, you can choose the HEIF (High Efficiency Image File) format for still-image capture. Smooth 10-bit colour depth provides realistic reproduction of skies and portrait subjects where subtle, natural gradation is essential. 5-axis optical image stabilisation Up to 5.5-step5 shutter-speed compensation from the in-body stabilisation unit The α7 IV's high-precision stabilisation unit and gyro sensors work together with image-stabilisation algorithms to achieve up to 5.5 steps4 of shutter-speed compensation, to maximise the high-resolution performance of the camera's 33.0‑MP2 image sensor. Sony's flash units coordinate with the camera's face-detection system Sony's latest flash units communicate fully with the α7 IV, leveraging its powerful face detection capabilities to adjust exposure to produce natural-looking skin tones6. Precise white-balance synchronisation and P-TTL metering, at up to the "Hi" level of continuous-burst speeds, reliably expose even fast-moving subjects with quick lighting changes, for unmatched dependability and creative possibilities.
External control of flash units  For greater convenience during shoots, compatible flash and radio wireless commander units connected to the α7 IV can now be controlled directly from the camera interface. Reliable autofocus, impressive speedFast Hybrid AF, evolvedThe Fast Hybrid AF system, combining phase-detection AF and contrast-detection AF, has evolved even further to achieve greater speed, accuracy, and tracking performance. With Sony's 4D FOCUS, a wide, dense AF area covers roughly 94% of the image area for both stills and movies with 7597 phase-detection AF points.10-frames-per-second8 continuous shooting with fast buffer release Both the mechanical and electronic shutters allow you to shoot more than 800 frames 9 at up to 10 fps8 with AF/AE tracking, thanks to the α7 IV's high-capacity buffer memory, speedy BIONZ XR processor, and improved memory card writing speed.Sony's smart AI-based Real-time Tracking10 Sony's unique subject recognition algorithm uses colour, pattern (brightness), and subject distance (depth) data to rapidly process spatial information in real time. AI is used to detect and track the eyes and face of the subject (human, animal or bird) with extremely high precision. Just select the subject to track, then leave it to the camera.
