Sony Alpha a7 IV Mirrorless Digital Camera

The full-frame 33MP Exmor R back-illuminated CMOS sensor delivers outstanding speed and superb image quality. The use of copper wiring contributes to higher transmission speeds and faster AD (analogue to digital) conversion, while fast sensor readout enables 10-bit 4:2:2 4K recording up to 60p. The sensor also provides improved color reproducibility, low-noise performance at all sensitivities, 15+stop dynamic range and increased AF (autofocus) speed and precision performance. Experience improved levels of color gradation and detail rendering as well as soft, natural-looking human skin textures.BIONZ XR image processor for up to 8x processing speedThe BIONZ XR engine, also used in the Sony Alpha 1 and Alpha 7S III models, provides up to an 8x increase in processing speed. The engine concentrates real-time processing of AF (autofocus), 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 to deliver fast response regardless of real-time processing load.Beautiful images with reduced noiseBuilding on the capabilities of the back-illuminated Exmor R image sensor, the powerful BIONZ XR processing engine reveals even higher subjective resolution combined with exquisite detail and texture even in medium and high sensitivity ranges. Impressively low levels of noise are achieved throughout the standard range of ISO 100-51200 (expandable to ISO 50-204800 for stills and ISO 100-102400 for movies).Wide, 15-stop dynamic rangeTaking advantage of the camera's full dynamic range of 15 stops, the Alpha7 IV uses image data from the sensor's 33-megapixels to render remarkably delicate detail in landscapes and scenery. This stunning image quality is based on Sony's unrivalled experience at the front lines of both still-image and movie creation.4K 60p recording, 4:2:2 10-bit recordingThe Alpha 7 IV gives you an impressive range of video recording options. Full pixel readout without binning allows 4K 60p recording in Super 35 mode providing high-resolution smooth footage that can be edited to 2x and 2.5x slow-motion when rendered to 30p or 24p in post-production, and 4K 24p or 30p full pixel readout without binning in full-frame with 7K oversampling. For highly detailed and rich 4K content.7K oversampling for beautifully expressive, richly detailed imagesThanks to the increased 33MP resolution, the Alpha 7 IV oversamples 7K when recording full-frame 4K movies at up to 30p, resulting in high-resolution, highly detailed 4K for beautifully expressive, rich images. Select the mode that best suits your purpose, and let the camera deliver.Beautiful color expression made simple, with S-CinetoneThe Alpha 7 IV supports S-Cinetone, based on expertise gained through development of the VENICE CineAlta professional cinema camera line. 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. It's easy to create a more expressive look for your movie imagery without post-editing, since S-Cinetone is processed in-camera.Breathing Compensation for consistent angle of view when focusingFor the first time in the Sony Alpha series, the Alpha 7 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 stabilization to shoot stable, consistent imagery.Visualize depth of field with Focus MapAnswering requests from professional creators, the brand-new Focus Map feature lets you easily visualize depth of field (DOF) and which areas are in and out of focus when you're in movie mode. In use, focus information (depth map) is overlaid on the display of the live view in real time. Areas in focus and within the set DOF appear translucent, while areas out of focus behind the DOF appear blue and those in front of the DOF appear red. Focus Map can be used in autofocus and manual focus modes and greatly enhances the ability to check focus and map depth of field.AF Assist for seamless transitions between AF and manual focusThe AF Assist function, inherited from the Cinema Line FX6, lets you seamlessly switch to and from autofocus and manual focus during movie shoots. When this feature is 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. Autofocus is resumed when ring rotation stops.Fast Hybrid AF with improved speed, precision and trackingThe Fast Hybrid AF system, combining 759 phase-detection AF points and 425 contrast-detection AF points with a wide coverage of roughly 94% of the image area for both stills and movies, has evolved even further to achieve greater speed, accuracy and tracking performance. This vast collection of data is analyzed in real time by the latest powerful BIONX XR processing engine to achieve the AF system's impressive results.Sony's smart AI-based Real-time TrackingThe superior power of the BIONZ XR processing 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 compared to Alpha 7 III. AI (Artificial Intelligence) is used to detect and track the eyes and face of the subject (human, animal or bird) with extremely high precision. 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.Improved Real-time Eye AFKeeping the targeted eye in focus so you can concentrate on composition. The high speed of the latest image BIONZ XR processing engine provides a significant boost to Real-time Eye AF performance, even when the subject is looking up, down, or sideways. It is also possible to use Touch Tracking to initiate Real-time Tracking of any subject in the frame, simultaneously initiating Real-time Eye AF if an eye is detected, simply by touching the screen.Pet photos made easyFast, accurate focus for difficult animal shots. By setting the camera's subject detection type to "Animal" in advance, you can automatically detect and track an animal's eyes, for greater success in both wildlife shots and photos and movies of your pets at home. Animal-eye detection has been improved with reliable tracking and accurate focus even when the animal's face is upside down.Real-time Eye AF for birds for stills and movieThe Real-time Eye AF function is now capable of detecting the eyes of birds and tracking them in real time, for both still shots and movies. The BIONZ XR processing engine runs optimized AF and tracking algorithms to ensure uninterrupted tracking even for birds in flight, whose movement is hard to predict. Once you've selected a bird, the camera will automatically detect and precisely track that bird's eye, whether the bird is perched or in flight.10-frame-per-second continuous shooting with massive bufferBoth the mechanical and electronic shutters allow continuous shooting of 33MP RAW+JPEG still images at up to 10 fps with AF/AE tracking. The powerful BIONZ XR processing engine and increased buffer memory allow faster writing to memory cards, so you can shoot more than 1000 compressed RAW+JPEG frames (more than 2000 altogether, up to a full memory card). Its even possible to capture over 800 uncompressed RAW+JPEG frames (more than 1600 altogether) in Hi+ mode. Increased processing power also allows you to change menu settings even while data is being written to the memory card.
