Sony a7R IIIA Mirrorless Camera

Blending Speed and Resolution
Proving that speed, resolution, and video capabilities can all coexist, the Sony a7R IIIA is a versatile, high-performance camera characterized by not only its resolution, but by its multimedia versatility.

42.4 MP Exmor R BSI CMOS Sensor and BIONZ X Image Processor
Featuring a back-illuminated design, the full-frame 42.4-megapixel Exmor R CMOS sensor works with the BIONZ X image processor to offer high-resolution stills and video while minimizing noise and improving speed. 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 42.4-megapixel 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 dynamic range using the full width of the full-frame sensor. 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 an impressive 15-stop dynamic range at low sensitivity values.

Autofocus and Image Stabilization
An evolved 4D FOCUS system now employs a combination of 399 phase-detection points, which cover approximately 68% of the frame, along with 425 contrast-detection areas for reliable and quick autofocus and subject tracking performance. This Fast Hybrid AF System now achieves twice the focusing speed and more reliable tracking compared to previous a7R models, as well as improved low-light focusing response down to -3 EV.
  • Lock-on AF maintains focus on moving subjects throughout the use of a configurable frame that is set over the desired moving subject
  • Expand Flexible Spot employs neighboring focus points to retain focus on moving subjects even if the originally selected point loses focus
  • Eye AF can be used to base focus on recognized human subjects eyes for portraits and is available in both AF-S and AF-C modes, for both stills and video. Eye AF can be used when photographing animal subjects, too, with any focusing mode when shooting stills
  • Focus Magnifier function can be used for critical focus when homing in on minute subject details
  • Rear touchscreen can also be used for Touch Focus control, and a Touchpad Focus Control mode lets you use the rear screen intuitively while keeping your eye to the viewfinder
  • For more personalized control over focus, and benefitting working in either vertical or horizontal shooting orientation, the AF area can be switched in orientation to better suit your subject matter
  • AF tracking sensitivity can also be customized in five steps to match how a subject is moving
  • Frequently used focus point settings can be memorized and recalled with a custom button for faster switching between focus settings
5-Axis SteadyShot INSIDE Image Stabilization
The a7R IIIA incorporates an enhanced 5.5-stop effective 5-axis SteadyShot INSIDE image stabilization system, which compensates for five different types of camera shake encountered during handheld shooting of stills and video. This allows users to confidently use any lens, even adapted lenses, for critical imaging without encountering blur from camera shake.

Body Design and Connectivity
Viewfinder and LCD Screen An updated Quad-VGA OLED Tru-Finder EVF is featured and has a 3.69m-dot resolution for bright, clear viewing in high detail. Both Standard and High-quality settings can be used, depending on the shooting situation, in order to optimize the viewing experience.

Connectivity
  • 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.
  • The a7R IIIA features a 3.5mm microphone input jack for compatibility with external microphones. And for users needing more, the camera is also compatible with the Sony XLR-K2M XLR Adapter for recording professional balanced XLR audio signals with phantom power and adjustable mic/line inputs. For monitoring audio, a 3.5mm headphone jack is available as well as real time audio levels for a visual reference.
  • Built-in Wi-Fi enables the a7R IIIA to instantly share imagery to mobile devices for direct sharing online to social networking, via email, and to cloud storage sites. 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.
