About Sony Alpha a7 IV

Sony Alpha a7 IV.

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 (analog 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 texture.

BIONZ XR Engine For 8X Processing Speeds.

The BIONZ XR engine, also used in the Sony Alpha 1 and Alpha 7SIII 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, Reduced Noise.

Building 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 50-204800for stills and ISO 100-102400 for movies).

Wide, 15 Stop Dynamic Range.

Taking 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.

The Alpha 7IV 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 Rich, Detailed Images.

Thanks 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-Cinetone.

The Alpha 7 IV supports S-Cinetone, based on expertise gained through development of the VENICE CineAlta professional cinema cameraline. 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.

Visual Depth Of Field With Focus Map.

Answering 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 thed isplay 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.

Sony's Smart AI Based Real Time Tracking.

The 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.

Instantly Turn Your A7IV Into A Live Streaming Webcam.

All it takes is a USB connection to turn the full-frame Alpha7 IV into a high-performance webcam. There's no need for complicated, advanced setup; just connect the camera to a computer or smartphone via USB, select "Live Stream (USB Streaming)", and you're set. You can choose from four different output formats, including high-resolution 4K video and simultaneous internal recording is also available, giving you broad flexibility to cover a wide variety of needs.

Handheld Movie Shooting With Active Mode.

Active Mode uses the camera's stabilization unit, gyro sensors and sophisticated algorithms for highly effective in-camera optical image stabilization during movie shoots. The powerful processing engine precisely detects the required amount of compensation for smooth stabilization in all formats, including 4K, without compromising the Alpha 7 IV's compact size and mobility. And, because the gyro data is also recorded alongside the video, even more effective post-production stabilization can be applied for ultra-smooth shots using Catalyst Browse/Prepare software.

Communication Features For Easy Sharing & Distribution.

The Alpha7 IVs equipped with robust wired and wireless communication features for more comfortable sharing and distribution. In-body wireless LAN uses a 5GHz band in addition to the 2.4GHz band(IEEE 802.11 a/b/g/n/ac standards are supported), for fast data transfer. Background FTP transfer of file scan be set to occur automatically while shooting continues, and a USB Type-C connector supports fast SuperSpeed USB 10Gbps(USB 3.2 Gen 2) data transfer.

Robust, Reliable Engineering.

The Alpha7 IV has improved dust and moisture resistance to provide outstanding reliability even in challenging outdoorshooting environments. Design refinements include more sealing at body seams and the battery compartment cover, a redesigned lens lock button, and extra cushioning around the mount. A lightweight, high-rigidity magnesium alloy used for the camera's top cover, front cover, and internal frame provides excellent durability.

Soft Skin Effect For Beautiful Skin Appearance.

The Alpha7 IV's built-in Soft Skin Effect is available in four level settings(OFF, LO, MID, and HI). It makes skin look bright and beautiful, softening wrinkles, blemishes and dull-looking areas while adding emphasis to the eyes and mouth. Complementing the capabilities of the full-frame sensor, this feature can add appeal to live-streamed sessions as well as enhancing still shots and movie.
