Another Milestone

61.0 effective megapixels, true-to-life gradations, and blazing speed come together in a full-frame mirrorless camera body that is capable of capturing reality you can almost feel. Image quality and expression that were once only possible with medium-format cameras are now available in a compact, lightweight α series full-frame body with features, connectivity, and reliability designed to support professional workflows both in the studio and out on location. Stunning stills and movies with professional reliability and productivity. Another milestone from the leader in mirrorless imaging.

Beyond Details

Extraordinary resolution and image quality with nuanced gradations capture more than details, encapsulating presence and atmosphere as well. The α7R IV represents a new level of full-frame mirrorless performance for serious applications.

New 61.0-megapixel Exmor R sensor

The α7R IV features a 35mm full-frame back-illuminated CMOS image sensor with approximately 61.0 million effective pixels, delivering depth and dimension that were once only available in medium-format cameras. Back-illuminated structure and effective noise reduction techniques combine to deliver an extraordinary blend of low noise and high sensitivity for enormous imaging potential.

BIONZ X Image processing maximizes sensor potential

Advanced Detail Reproduction Technology and Area-specific Noise Reduction, both features of Sony’s BIONZ X image processing engine, have been carefully tuned to maximize the performance of a sensor that offers approximately 1.5 times more resolution than the highly acclaimed α7R III, achieving extremely fine, realistic reproduction of textures and details. Wide dynamic range is another advantage, with approximately 15-stops* available at low sensitivities for smooth, natural gradations from the deepest shadows to the brightest highlights. Portrait skin tones and the colors of nature are rendered with breathtaking realism.

Up to ISO 32,000 with undiminished quality

A standard ISO range that extends from ISO 100 up to ISO 32000 and is expandable to ISO 50 ~ ISO 102400 for still images makes it possible to achieve optimum image quality in just about any light. Noise is effectively minimized even at high sensitivities, maintaining excellent image quality even with this sensor’s high pixel count.

16-bit processing and 14-bit RAW output

Image sensor output is processed in 16-bit form by the front-end LSI and BIONZ X processor before being output as compressed or uncom-pressed 14-bit RAW files that have smoother, more natural gradations for higher overall image quality. 14-bit RAW output is available even when shooting in silent or continuous mode.*UXGA OLED Tru-FinderQVGA OLED Tru-FinderNEWNEWNEWNEWNEW* Limited to 12 bits during compressed RAW continuous shooting, BULB exposure, or when Long Exposure NR is ON.

Reliable low-vibration shutter

Shutter vibration that can cause blur is reduced to a minimum, even when shoot-ing continuous bursts at up to 10 frames per second, thanks to a new shutter unit with a fast-response coreless motor. The system also includes a brake that sub-dues mechanical front and rear curtain shutter vibration, and dampers that absorb mechanical shock. Low shutter vibration is critical to achieving full quality from the camera’s high-resolution image sensor. The shutter is also quiet, and has been tested for durability in excess of 500,000 shutter cycles.

5-axis image stabilization

A precision stabilization unit and gyro sensors work with refined image stabilization algorithms to achieve up to a 5.5-step* shutter speed advantage that also supports the high-resolution capabilities of the 61.0-megapixel sensor. The live view image is also stabilized while shooting stills, making it easier to frame and focus when using a telephoto or macro lens. In-body image stabilization means that effective stabilization can be achieved with a wide range of lenses. 5-axis image stabilization is effective for movies as well as stills.

A clearer view

5.76 million-dot UXGA OLED Tru-Finder

The α7R IV features a new UXGA (Ultra-XGA) OLED Tru-Finder with 5.76 million dots, for outstanding detail, contrast, and brightness. A “High” quality mode provides extra fine viewfinder and monitor displays with minimal moiré and jaggies, for finer detail and a more natural overall view, and a 120/100fps* finder frame rate setting provides a smooth viewfinder image with minimum display motion blur when shooting moving subjects. The eyepiece window is fluorine coated to repel fingerprints and grime, and make it easier to clean.

*NTSC/PAL

16-image Pixel Shift Multi Shooting

This feature takes advantage of advanced in-body image stabilization system control, capturing multiple pixel-shifted images that are later composited using a computer to achieve overwhelming resolution in a single image. In addition to 4-image composites, the α7R IV is capable of producing 16-image composites with approximately 240.8 million pixels (19008 x 12672 pixels) from data that is equivalent to approximately 963.2 million pixels. The result is photographs with detail and presence that are simply stunning. Resolution, color, and material textures are astonishingly realistic even when the image is enlarged by more than 100%.

Note: The Imaging Edge (Remote/Viewer/Edit) desktop application is required for compositing. Image compositing may not be successful if camera or subject movement causes blur. Some restrictions apply to flash and other devices.

Capture with Confidence

Sony’s lead in mirrorless imaging can be partly attributed to an uncompromising approach to blending high AF speed and performance with high resolution. A fraction of a second and the resolution needed to crop when necessary can separate the great from the mundane.

4D FOCUS – Wide, fast, reliable AF gets the shot

The new image sensor in the α7R IV features 567 phase detection points in a high-density focal plane phase-detection AF system, covering approximately 99.7% of the image area vertically and 74.0% horizontally. High-density focal plane phase-detection works with 425 contrast AF points in a Fast Hybrid AF system that can handle a huge volume of data at high speed, snapping rapidly into focus with just about any subject and situation. Tracking performance has been improved too, despite the significant increase in resolution.

Reliable AF in low light

Advanced AF algorithms contribute to high AF precision down to light levels as low as EV-3* in the AF-S mode. The α7R IV also includes a Focus Priority mode, providing more reliable AF in low light when using smaller apertures. When shooting at a smaller aperture with large studio strobes, for example, the Focus Priority mode uses available light to focus with the aperture open right up until the instant before actual exposure,** making it possible to focus on moving subjects with greater precision. All of this makes AF substantially more precise and reliable in dark scenes.

*ISO 100 equivalent, F2.0 lens.
**AF-C mode only. Operation varies according to the lens used and shooting conditions. When shooting continuously with an aperture of smaller than F11. Focus is fixed at the first frame of the sequence.

Serious Speed

Class-leading speed and high-resolution continuous shooting with accurate AF/AE

An advanced mechanical shutter unit and updated image processing algorithms allow continuous shooting at up to 10 fps* with accurate AF/AE tracking, even with this camera’s high-resolution 61.0 effective megapixel sensor. With this type of speed, you won’t miss the most photogenic moments and expressions of moving subjects. It is also possible to shoot continuously at up to 8 fps* in live view mode, with minimal viewfinder/monitor display lag for easy, stable framing, even with dynamic subject motion. When using the APS-C crop angle of view you have approximately 26.2 million pixels that can provide extra reach for bird photography, for example.

* Up to 10 fps in continuous “Hi+” mode, and up to 8 fps in continuous “Hi” mode. Maximum fps will depend on camera settings.

Up to 68 images per continuous burst

Buffer memory has been increased by 1.5x, allowing up to 68* Extra Fine/Fine JPEG or compressed RAW images to be captured in one contin-uous burst. Approximately 3x more continuous images can be captured in the APS-C mode, so you can shoot continuously with confidence.

*“Hi+” continuous mode with mechanical shutter. UHS-II compatible SDXC memory card. Sony test conditions.

Another evolution in Real-time Eye AF (Human)

Real-time Eye AF employs artificial intelligence to detect and process eye data in real time, and track the subject’s eye with unprecedented precision. This function can be activated via an assigned custom key, or by simply pressing the AF-ON button or half-pressing the shutter button. When used with the Real-time Tracking function, tracking will continue even if the camera is temporarily unable to locate the subject’s eye, so it is easier than ever to shoot dynamic portraits of moving subjects. Response when using a custom key assignment has been improved for even faster shooting.

Right/Left eye selection

In addition to automatic eye selection when using Eye AF, it is also possible to manually preselect the subject’s right or left eye. This can be an advantage for portraiture in which the eye to be focused on is predetermined, allowing the photographer to concentrate on composition, lighting, and other details. This function works for both stills and movies.*

*Not available when using Eye AF for animals.

Eye AF takes an evolutionary leap

Real-time Eye AF animal mode* tracks animal eyes

Advanced AI-based subject recognition technology now allows fast, precise, automatic detection and tracking of animal eyes.* This new capability can vastly increase success rates when photographing animals in a variety of settings or pets at home. Real-time Eye AF animal mode can be initiated either by pressing an assigned custom button or by half-pressing the shutter button.**

*Accurate focus may not be achieved with certain subjects in certain situations.
** Stills only. “Animal” mode must be selected via the Face/Eye AF Settings menu before shooting.

In the Studio

Outstanding image quality is a prerequisite for professional photography. In order to deliver the required level of quality the pro shooter needs features that maximize speed and productivity in the studio or on location, without disrupting the creative flow.

Enhanced productivity for the working pro

PC Remote (tethered) shooting, where data is directly transferred to a computer so it can be viewed on a large monitor by staff and clients, is essential for smooth, productive workflow at model and product shoots. The α7R IV offers high-speed wired and wireless tethering capability with a number of file transfer and sorting options for maximum flexibility.

Fast USB connection

A USB Type-C™ connector that supports fast USB 3.2 Gen 1 data transfer is provided. This makes high-speed PC Remote data transfer available while shooting for smooth handling of large image files. Efficient data handling both at the camera and computer ends of the connection results in transfer speeds approximately 2x faster than the α7R III, for smooth transfer of large uncompressed RAW image files without interrupting the flow of the session.

Creative Moviemaking

The α7R IV provides new support for creative moviemaking with improved overall AF performance and Real-time Eye AF. For 4K movies, 6K oversampling delivers an overwhelming sense of depth and detail, while an HLG picture profile facilitates HDR content creation.

Record reality in spectacular 4K

Full pixel readout without binning in Super 35mm mode for high-resolution 4K movies

Full frame and Super 35mm* formats can be selected for 4K movie record-ing. Full pixel readout in the Super 35mm mode (approx. APS-C 16:9), without the need for pixel binning, makes it possible to condense ap-proximately 2.4 times** the amount of data required for 4K movies (QFHD: 3840 x 2160), resulting in high-resolution, high-detail 4K with minimal moiré and jaggies. Further-more, the advanced image process-ing system delivers more accurate skin tones as well as smoother high-light gradations. 4K recording em-ploys the XAVC S*** format at bit rates as high as 100 Mbps.

*Super 35mm 4K recording results in a slightly narrower angle of view
**24p recording. Approx. 1.8 times for 30p recording.
***A Class 10 or higher SDHC/SDXC card is required for X AVC S format movie recording. UHS speed class 3 or higher is required for 100 Mbps recording.

Fast Hybrid AF for movies

A refined Fast Hybrid AF system achieves faster, smoother, more stable autofocus during movie recording. Consistent, stable tracking is maintained even if an object temporarily moves in front of the main subject, or a small aperture must be used. This greatly reduces the need for manual focus ad-justments when the camera is used on a gimbal, for run-and-gun projects, or in other one-operator shooting situations.

Real-time Eye AF for movies

Human eyes can now be automatically identified and precisely tracked while shooting movies, so the operator can concentrate on the content rather than focus. The same Touch Tracking functionality that is provided for stills is also available for movie shooting, easily initiating Real-time Eye AF tracking on a specified eye. Right/left eye selection is available for movies too.

Touch Tracking for movies

Touch Tracking is also a boon for movie recording. Touch the subject to be tracked on the monitor, and the Real-time Tracking function will then process color, pattern (brightness), distance (depth), and face information to precisely and smoothly track the selected subject at the specified sensitivity and speed. It is also possible to half-press the shutter button or press the AF ON button while shooting to achieve fast focus (AF-S). This can be an advantage for weddings or documentaries, where there is only one chance to capture a scene. In such cases the focus area selected in advance is applied.

Instant HDR workflow
*Connect this product to an HDR (HLG) compatible Sony TV via a USB cable when displaying HDR (HLG) movies.

Slow & Quick Motion

Frame rates from 1 fps to 120 (NTSC)/100 (PAL) fps can be selected in eight steps for up to 60x quick motion and 5x slow motion, recordable at up to 50 Mbps with full-HD quality.

S-Log3 for wide 14-stop dynamic range

In addition to S-Log2, S-Log3 is available for better gradation from shadows to mid-tones (18% gray), and a dynamic range of up to 14 stops. Both of these S-Log gamma curves provide extra margin for post processing, making it easier to achieve wide dynamic range.

Proxy

4K movies and lower-resolution proxy movies can be recorded simultaneously. The smaller proxy files are ideal for quick previewing.

Time-lapse movies document the passing of time

In-camera interval shooting is now possible without the need for addi-tional apps. Depending on the number of pixels, interval sequences can be converted to 4K time-lapse movies.* A variable-speed preview function lets you see how the finished movie will look right on the camera monitor.

*Use the latest versions of the Imaging Edge and PlayMemories Home software.

Other movie features

Picture profiles, Clean HDMI, Time Code/User Bit, REC control, Gamma Display Assist, a Zebra function, and other details provide comprehensive support for advanced video workflows.
