SONY - ALPHA 7 R IV (boitier nu)

Description

Enter a whole new world of photographic expression with incomparable image quality and processing speed. A powerful new choice joins the α7R series with ever more advanced connectivity and enhanced reliability demanded by pros.

The 61.0-megapixel full-frame Exmor R™ CMOS sensor combined with BIONZ X™ imaging engine delivers unprecedented resolution, fine gradation, and low noise to open entirely new dimensions of detail just as pro photographers expect. The α7R IV captures the mood of each scene and the texture of subjects.

The Alpha 7R IV is equipped with a built-in five-axis image stabilization system that has been improved in every detail. The photographers have 5.5 stops speed. The shutter has also been redesigned to limit the slightest movements and vibrations.

The Alpha 7R IV is equipped with a built-in five-axis mechanical image stabilization system that has been improved to the smallest detail to allow shooting in very high definition. This gives photographers more flexibility in shooting up to 5.5 stops of speed. The shutter has also been redesigned to limit the smallest movements and vibrations that can cause blur effects.

The Alpha 7R IV also features the most powerful viewfinder of any Sony camera to date: an electronic UXD Tru-finder UXGA viewfinder at 5.76 million points. With its 1.6x resolution superior to that of the Alpha 7R III, this new viewfinder makes it possible to restore the scenes framed in the smallest details with a great realism. Adjustment optimizes the image refresh rate; "Standard" and "High" modes are available with a refresh rate of 60 and 120 frames / sec to best suit the subject and shooting conditions.

The Alpha 7R IV also offers an advanced Pixel Shift mode, allowing multiple shooting up to 16 full resolution images. When in this mode, the camera shifts the sensor in increments of 1 or 0.5 pixels and captures up to 16 individual pixel-pixel images, containing a total of 963.2 megapixels of data. The dedicated application Sony Imaging Edge ™, available for free on PC and MacOS can then assemble these images into a single image of 240.8 million pixels is an image of 19008 pixels x 12672 pixels. This definition is ideal for architectural photographs, works of art and still life in general, this advanced mode produces images displaying a level of detail and color accuracy just incredible.

The innovative full-format hybrid Alpha 7R IV camera can capture full-resolution images at a frame rate of 10 frames / sv, with accurate and continuous AF / AE tracking for approximately 7 secondsvi in full-frame and full-frame mode (JPEG / RAW), and for about 20 seconds in APS-C crop mode, for 26.2-megapixel images. These speed-optimized performances capture moving subjects with extreme precision and incredible detail.

The redesigned focus system of the Alpha 7R IV consists of 567 phase detection focus points, covering approximately 74% of the image area and 425 contrast-sensitive focus points. . These two focusing systems combine to enhance the accuracy and reliability of focusing in low light conditions and in low contrast situations. The high number of AF detection points associated with the latest focusing algorithms allow the Alpha 7R IV to follow the complex or sudden movements of a subject with unprecedented accuracy and reliability.

The Alpha 7R IV also incorporates Eye AF real-time AF, which relies on artificial intelligence (AI) to detect and process eye position data in real time, and lock onto the camera. subject's eye with extreme precision. This feature is available for human eyes but also for the eyes of animals. An option to choose one or the other possibility according to the shooting.

The original real-time tracking functionvii of the subject "Real-time Tracking" is also available and optimized; it implements a new subject recognition algorithm to guarantee optimal tracking and locking of the focus system on the subject. The camera also features an anti-flicker shooting mode that automatically detects fluorescent or artificial lighting to reduce the impact of the frequency on the final image.

The Alpha 7R IV also features a range of advanced connectivity features designed to enhance workflows. The new model includes a WLAN network function that is compatible with the traditional 2.4 GHz band and the 5 GHz high bandwidth for faster and more stable data transfer. Remote PC wireless connectivity (wireless connection shooting) is also available, a first for Sony cameras. Claimed by many professional users, this feature provides greater freedom for studio and field shots, allowing the photographer to move freely without sacrificing high-speed Wi-Fi® data transfer. box to the computer.

In addition to high-speed Wi-Fi® and wireless PC connectivity, the new full-format Alpha 7R IV is equipped with a USB Type C ™ SuperSpeed connector (USB 3.2 gen1) that provides extremely fast wired transmission of data, speed and This transfer can be doubled compared to the Alpha 7R III if you use the Imaging Edge software at the same time. The device also allows data transfer over FTP with a background transfer option, to send your images to a defined remote FTP server while you continue to take photographs or are in image replay mode.

For more efficient and faster connected professional workflows, Sony announced version 2.0 of its desktop applications "Imaging Edge" ("Remote" / "Viewer" / "Edit"). The "Remote" application allows the user to control the camera and follow his shooting live from a PC screen. The "Viewer" application allows you to quickly preview, rate and select photos in large libraries. Finally, the "Edit" application allows you to develop RAW data in order to obtain high quality photos.

For an even more convenient transfer, you can use the latest version of Sony's Imaging Edge Mobile ™ application to send your images to a connected smartphone, even in off-camera mode.
