Overview

Overview

The Sony Alpha a7R IV Full Frame Mirrorless Digital Camera features a newly developed 35mm full-frame, back-illuminated CMOS image sensor with a resolution of 61 megapixels, the first of its kind. The back-illuminated structure and effective noise reduction techniques combine to deliver extremely low-noise and high-sensitivity performance, ensuring the absolute maximum image quality. The camera also boasts an impressive 15-stop dynamic range at low sensitivities, resulting in smooth natural gradations ranging from deep shadows to highlights, and utilizes algorithms from many of the latest Alpha cameras to maintain outstanding color reproduction.  

The a7R IV is equipped with an innovative 5-axis, optical, in-body image stabilization system that has been fine-tuned to support its high-resolution shooting capacity, resulting in a shutter speed advantage of 5.5-steps1. Additionally, the shutter unit assembly has been carefully redesigned to reduce even the slightest movement that may cause blur. The camera also includes Sony’s highest resolution viewfinder to date, a 5.76 million dot UXGA OLED Tru-finder EVF. With approximately 1.6x the resolution of the EVF in the a7R III, this new viewfinder provides an extremely accurate, true-to-life depiction of the scene being framed. The display quality can be set to ‘Standard’ or ‘High’ mode, and to either 60 fps or 120 fps refresh rate to best match the subject and shooting conditions.  

The a7R IV also features an evolved Pixel Shift Multi Shooting2 mode that composites up to 16 full-resolution images. In this mode, the camera precisely shifts the sensor in one pixel or half-pixel increments to capture 16 separate pixel-shifted images containing a total of 963.2 million pixels of data, which are then composited into a 240.8 million pixel (19008 x 12672 pixels) image using Sony's "Imaging Edge" desktop application3. Ideal for photographing architecture, art, or any other still life subject, this enhanced mode produces photographs with a level of detail and color accuracy that is simply stunning. 

Shooting & Focusing Speed

The Alpha 7R IV can shoot full resolution images at up to 10 fps with continuous, accurate AF/AE tracking for up to approximately seven seconds in full-frame, full-resolution mode (JPEG / RAW), and approx. 21 seconds in APS-C crop mode, delivering 26.2MP images. These high-speed options ensure that fast moving subjects can be captured with extreme accuracy and incredible image detail. 

The upgraded focusing system of the Alpha 7R IV is comprised of 567 focal-plane phase-detection AF points that cover approximately 74% of the image area. There are also 425 contrast AF points that add extra precision and reliability for low light and other situations that are best served by contrast AF. The higher AF sensor density and refined tracking algorithms of the new camera produce a notable improvement in tracking performance, allowing complex subject motion and sudden subject movements to be reliably tracked with greater precision than ever before.

The Alpha 7R IV also supports Real-time Eye AF, which employs artificial intelligence to detect and process eye location data in real-time, locking and maintaining focus on the subject's eye with extreme precision. This is available for both animal and human subjects, with either animal or human Eye AF mode selectable depending on the shooting situation.  Real-time Tracking is available as well, which utilizes a newly developed subject recognition algorithm to ensure the ultimate subject tracking, and persistence of the focusing system.  There is also an anti-flicker shooting4 mode, which automatically detects the presence of fluorescent or artificial lighting in a shooting environment to minimize any impact on the final image. 

Enhanced Connectivity for Professional Workflow 

The a7R IV includes wireless LAN functionality to support the conventional 2.4 GHz band, as well as a high-speed 5 GHz band5 for faster, more stable data transfer. Wireless PC remote connectivity (wireless tethering shooting) is also available, a first for Sony cameras. Requested by many professionals, this allows greater freedom in studio and location shooting, letting the photographer work without restriction.

In addition to high-speed Wi-Fi and wireless PC connectivity, the a7R IV is equipped with a SuperSpeed USB (USB 3.2 Gen 1) USB Type-C connector that supports extremely fast wired data transmission, with almost double the data transfer speed achieved in combination with Sony's Imaging Edge software, compared to the Alpha 7R III. It also supports FTP data transfer with background transfer capability, allowing photographers to send images to a specified FTP remote server while they are still shooting or reviewing images.

To support an efficient, high-speed, connected professional workflow, Sony has announced version 2.0 of its "Imaging Edge" desktop applications ('Remote'/'Viewer'/'Edit'). The 'Remote' application allows users to control cameras and monitor live shooting on their computer monitor, the 'Viewer' application is used to quickly preview, rate and select photos from large libraries, and the 'Edit' application can develop RAW data into high-quality photos for delivery. 

To maximize convenience in image transfer, when utilizing the latest version of Sony’s Imaging Edge Mobile application6, the camera can now transfer images to a connected smartphone even if camera power is set to OFF7

High-Resolution 4K & Professional Filmmaking Features 

In addition to its impressive still image capabilities, the new Alpha 7R IV performs exceptionally well as a serious filmmaking tool, offering 4K (3840 x 2160) video recording across the full width of the image sensor, and full pixel readout without pixel binning in Super 35mm mode. This ensures high-quality 4K footage with exceptional detail and depth. S-Log 2 and S-Log 3 are also available, to maximize color grading flexibility, with S-Log 3 offering a total of 14-stops of dynamic range.  Hybrid Log-Gamma (HLG)8 is also available on the a7R IV to support an Instant HDR workflow.

For video autofocus, the camera utilizes a refined Fast Hybrid AF system that achieves faster, smoother, more stable autofocus during video shooting (even if an object temporarily moves in front of the intended subject). The camera also includes Touch Tracking functionality during movie shooting, allowing the user to simply touch the screen on their intended subject for instant acquisition.

The a7R IV debuts Real-time Eye AF for movie shooting, a first in any of Sony's cameras. When activated, the eye of a subject is automatically tracked with high precision and reliability, allowing the shooter to focus on the content itself as opposed to what is in focus or not. The aforementioned Touch Tracking functionality will also automatically initiate Eye AF when a human subject is selected. 

Another notable video feature is the addition of a digital audio interface to the camera's Multi Interface (MI) Shoe, enabling a direct, digital connection from the new, optional ECM-B1M Shotgun Microphone or XLR-K3M XLR Adaptor Kit for clear, low-noise, high-quality audio recording. Interval shooting for creating time-lapse videos is available, as well as full HD recording at up to 120 fps, Slow and Quick Motion9 functions, and much more.

Enhanced Design, Construction & Customizability

The a7R IV benefits from several upgrades to its design and usability, with many adjustments being implemented directly from the input of Sony's professional community. To maximize durability, the new Alpha 7R IV features upgraded dust and moisture resistance10, with additional sealing at all body seams, battery compartment cover, and media slots. The camera frame is constructed from an extremely lightweight and durable magnesium alloy, with an upgraded 6-screw, extra-rigid lens mount. 

Additional enhancements to the body design include an improved grip for greater comfort and a more sure hold, an increase in the diameter and feedback for the 'AF-ON' button, a new multi-selector joystick design for improvised control, an exposure compensation dial lock button, and a redesigned shape and new position for the rear dial. The camera also includes (2) UHS-II compatible media slots for higher overall capacity and faster read/write speeds. 

For added convenience, camera setting registration is expanded. Now, almost all camera settings can be saved to, and loaded from, an inserted memory card. Up to ten combinations can be saved to any individual card and loaded into any camera body of the same model.

Despite its increased pixel count compared to the a7R III, the battery life has been improved with a CIPA measurement of up to 670 still images per charge using the LCD monitor, or 530 images with the EVF. For longer uninterrupted operating time, the new, optional VG-C4EM Vertical Grip holds (2) NP-FZ100 batteries, and the optional Multi Battery Adaptor (NPA-MQZ1K) can hold up to four Z batteries. The body can also be powered via the USB connector11
