Key Features
- 61MP Full-Frame Exmor R BSI CMOS Sensor
- BIONZ X Image Processor & Front-End LSI
- 567-Point Phase-Detection AF System
- UHD 4K30p Video with HLG & S-Log3 Gammas
Moving to an even higher resolution realm, the Sony Alpha a7R IV continues the noteworthy series of highly capable full-frame cameras, characterized by impressive stills and video performance and versatility. This fourth edition of the a7R sees the inclusion of an updated 61MP Exmor R BSI CMOS sensor and enhanced BIONZ X image processor, which afford impressive imaging results with marked smoothness, a 15-stop dynamic range, and, of course, speed. Up to 10 fps shooting is possible along with the ability to record UHD 4K30 video, both with support for Real-time Eye AF and Tracking AF technologies. The revised sensor design uses a Fast Hybrid AF System, with 567 phase-detection autofocus points, for notably fast and accurate focusing performance. Despite being such a high-resolution sensor, it is also distinguished by its flexible native sensitivity range from ISO 100-32000 for working in a variety of lighting conditions. Additionally, benefitting both stills and video operation, the a7R IV retains the 5-axis SteadyShot INSIDE sensor-shift image stabilization, which is effective to minimize the appearance of camera shake by up to 5.5 stops. Dual SD card slots are both UHS-II-rated for faster performance and the inclusion of a USB Type-C port permits tethering and quick in-camera battery charging. Additionally, built-in Bluetooth and both 2.4 and 5 GHz Wi-Fi bands afford wireless transferring and remote camera control from linked mobile devices
61MP Exmor R BSI CMOS Sensor and BIONZ X Image Processor
Featuring a back-illuminated design, the full-frame 61MP Exmor R CMOS sensor works with the BIONZ X image processor to offer impressively high-resolution stills and video while minimizing noise, improving speed, and achieving a wide 15-stop dynamic range. This sensor structure works with gapless on-chip lens design and an anti-reflection coating, as well as eliminating the optical low-pass filter, to improve light collection and enhance detail. Also, the copper wiring layer dramatically improves data transmission speed for creating 14-bit, high-resolution 61MP stills with a native sensitivity range from ISO 100-32000, which can be further expanded to ISO 50-102400. Also, it enables internal UHD 4K video recording with a wide 14-stop dynamic range using either the full width of the full-frame sensor or an APS-C-sized area. The BIONZ X processor also works in conjunction with a high-speed front-end LSI to realize faster processing times along with the ability to capture this impressive 15-stop dynamic range with smooth tonal rendering.

Body Design with Wi-fi & Bluetooth
- An updated UXGA OLED Tru-Finder EVF is featured and has a 5.76m-dot resolution for bright, clear viewing in rich detail, and a dedicated High quality setting enables a 120 fps refresh rate for especially smooth playback of moving subjects.
- In addition to the EVF, a 3.0” 1.44m-dot rear LCD is also available, which has a touch panel design for intuitive operation and focusing control. The screen also tilts upward 107° and downward 41° to benefit working from high and low angles.
- Magnesium alloy chassis assures rigidity, durability, and stability while remaining lightweight. The lens mount has also been improved to better support heavy lenses and the grip rigidity has been improved for more comfortable hand-holding.
- Extensive weather-sealing, including enhanced sealing around the battery cover, terminal cover, and chassis joints, has been employed to resist dust and moisture for reliable operation in harsh weather conditions.
- Using the same NP-FZ100 battery as its predecessor, the a7R IV’s battery life is rated for approximately 530 shots per charge with the EVF or 670 shots with the rear LCD.
- Dual SD memory card slots allow for flexible file saving and handling and can be configured to partition raw and JPEG files or can be used for overflow recording. Both of the card slots are rated to support UHS-II memory cards for faster transfer speeds.
- Integrated PC sync terminal for wired flash sync with strobe packs or wireless radio remotes.
- A USB 3.2 Gen 1 Type-C port has been added, in addition to a micro-USB port, for faster, more reliable tethering support. The USB Type-C connection allows the camera to be charged from the host power source while connected.
- Updated Multi Interface Shoe supports working with the optional ECM-B1M Shotgun Microphone or XLR-K3M XLR Adapter Kit, which provide improved, clear audio recording sound by sending a digital audio signal to the camera, opposed to an analog signal.
- The a7R IV also features a 3.5mm microphone input jack for compatibility with external microphones.
- Built-in Wi-Fi enables the a7R IV to instantly share imagery to mobile devices for direct sharing online to social networking, via email, and to cloud storage sites. Support for both 2.4 and 5.0 GHz bands also enables wireless tethered shooting support. NFC (Near Field Communication) is also supported, which allows for one-touch connection between the camera and compatible mobile devices; no complex set-up is required. Once connected, the linked mobile device can also display a live view image on its screen and remotely control the camera’s shutter.
- Bluetooth connectivity allows for location data acquisition
Fast Hybrid AF (Auto focus) system
An updated Fast Hybrid AF system now employs a combination of 567 phase-detection points, which cover approximately 99.7% of the height and 74% of the width of the frame, along with 425 contrast-detection areas for reliable and quick autofocus and subject tracking performance. This focusing system also achieves especially quick speed and reliable tracking, as well as enhanced low-light focusing response down to -3 EV. The use of phase-detection points also enables the use of A-mount lenses via the optional LA-EA3 or LA-EA1 lens mount adapters with full continuous AF/AE tracking compatibility.
