Product Description

Sony a7R III Alpha Mirrorless Digital Camera Body Only

The Sony a7R III combines optimum speed, video performance and resolution for a high performance and versatile camera. Built on a 42.4MP Exmor R BSI CMOS sensor, combined with the BIONZ X image processor the Sony a7R III can shoot up to 10 frames per second continuously and with improved autofocus performance images are clear, and crisp even when tracking objects at higher speeds.   Sony's Fast Hybrid AF system uses 399 phase-detection points and 425 contrast detection areas for ultra-fast and reliably accurate focus in challenging lighting conditions and will hold focus on your subject.    A sensitivity range from ISO 100 to 32000 and the ability to expand that ISO from 50 to 102400, boosts the a7R III low light performance with exceptional depth of tone, color and image clarity.   Record video in full 4K UHD using the full width of the sensor or switch to Super35 with 5K oversampling to minimize moire, typically seen when videoing intricate or repetitive patterns, and aliasing or "jaggies" for beautifully smooth video.  The Sony a7R III uses Sony's 5 axis INSIDE sensor-shift image stabilization technology, helping both your still and video shots by reducing camera shake by up to 5.5 stops.    A revitalized body design includes a 3.69m-dot Tru Finder OLED electronic viewfinder for true and natural monitoring of your images and a rear three-inch tilting 1.44m-dot touchscreen LCD viewer giving you easy access to controls.   The magnesium alloy body of the a7R III is both lightweight and durable, made to be dust and moisture resistant.  

About the Sony 42.4MP Exmor R BSI CMOS Sensor and BIONZ X Image Processor

This full frame 42.4 mega pixels CMOS sensor features a back-illuminated design for the best in low light performance.  The sensor's copper wiring layout drastically improves data transmission speeds and when combined with the BIONZ  X image processor and a high-speed front end LSI processing times are exceptionally fast and an incredible 15 stop, wide dynamic range at low sensitivity values.  The sensor is paired with a gapless on-sensor lens design with an anti-reflection coating for enhanced light gathering and detail.   The sensor and processor combination also avails fast continuous shooting at up to 10 fps at full resolution, for up to 76 consecutive frames, and with full-time AF/AE when working with either a mechanical shutter or an electronic shutter. If shooting in live view mode, a continuous shooting rate of up to 8 fps is also possible.
About the Sony Fast Hybrid AF System
Sony's Fast Hybrid Auto Focus system utilizes 399 phase detection points, covering approximately 68% of the image frame which work in conjunction with 425 contrast detection areas for reliably fast and accurate autofocus and subject tracking.  This system is twice as fast and more reliable than prevous a7R models with an improved low light focusing response down to -3 EV so you can easily, quickly and reliably focus even in difficult low light or high-speed shooting scenarios.  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.   The a7R III also has a variety of focusing functions including Lock-On AF allowing you to focus on moving subjects and Expand Flexible Spot focus, which uses adjacent focus points to maintain focus on moving subjects even when your originally selected point moves out of focus.  Eye AF mode can be used to centralize focus automatically on a subject's eyes for gorgeous portrait images.  The AF system can be used in conjunction with the Focus Magnifier option for critical focus when your subject is minute detail.   The rear touchscreen can be used for touch focus control.   Whether you are shooting in landscape or portrait, the AF system can be changed in orientation to better suit your subject for truly refined and customizable focus.  Tracking sensitivity can be customized as well in just 5 steps to match how the subject is moving and which focus points are most often used.  These are then memorized and recalled with a custom button for instant switching between focus modes.  
Sony's 5 Axis SteadyShot INSIDE Image Stabilization Technology
The SteadyShot INSIDE IS technology is effective up to 5.5 stops in reducing camera shake.   Designed to counteract 5 different types of camera shake, you can shoot with confidence regardless of the lens used.  When long focal length lenses are in use, the stabilization system will adjust for pitch and yaw.  For micro and high magnification lenses, horizontal and vertical shift compensation will ensure your images aren't blurred and ruined by those unavoidable, slight movements.  Roll compensation benefits all shooting styles and all 5 axes of stabilization will function at all times whether you use Sony or 3rd party lenses. 
UHD 4K Video Recording in XAVC S Format
Record UHD 4K movies with the a7R III in multiple frame rates up to 30fps.   5K resolution oversampling on a Super35mm recording area provides enhanced video performance, greater detail and full pixel readout without pixel binning for reduced moire and aliasing.  Full frame 4K video recording is also improved for higher quality in mid to high sensitivities allowing for use of the entire sensor width.  Full HD 1080p video recording can be done in rate up to 120 fps, and both resolutions utilize the 100 Mbps XAVC S format contained within an MP4 wrapper with 4:2:0 sampling. The high-speed, 120 fps recording also enables 4x and 5x slow-motion movie recording with the frame rate set to either 30p or 24p. In addition to high-resolution internal recording, uncompressed HDMI output also enables the use of an optional external recorder for clean 4K recording with 4:2:2 sampling. Produce 8MP stills from your 4K video recording in playback simply by taking a frame grab and storing it as a separate file, in camera.  
Additional Video Features
Support for HDR Content:
  • Affording extensive customizable color and gamma controls, the a7R III allows users to adjust the gamma, black level, knee, color level, and more. Also, users can use the same S-Log2 Gamma Curve that is found on high end Sony Cinema cameras that squeezes up to 1300% more dynamic range into the video signal then traditional REC709, for increased post-production flexibility. HLG (Hybrid Log-Gamma) support is also available, along with the BT.2020 color space, for recording within a wide color gamut and, in addition to S-Log2, S-Log3 is also available for producing an effective 14-stop dynamic range with increased grading control in the shadow to mid-tone regions of the image.

Slow & Quick Motion:
  • Take more control over your video capture capabilities with a variety of new frame rates available in an S&Q mode. This will allow shooters to capture Full HD video at one of either steps between 1-120 fps. These settings will allow you to slow down action as well as speed up a slow-moving scene. This setting is also NTSC/PAL switchable.

Enhanced Zebra Function:
  • An enhanced Zebra function is ideally suited to aid in monitoring exposure values in high-contrast scenes. Video signal level targets can be set from 0 to 109, and specific ranges can be set to make exposure level adjustments easier.

Time Code and User Bit Settings:
  • A time code can be used to record hours, minutes, seconds, frames on image data for more precise editing while the User Bit function can record date, time, and scene number to aid in editing together footage from multiple cameras.

Proxy Recording:
  • UHD 4K movies and lower-resolution proxy movies can be simultaneously recorded. The smaller proxy files are ideal for quick previewing or pre-editing that can reduce the time required for final 4K editing.
Body Design and Built-In Wi-Fi/Bluetooth
  • 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. This updated viewfinder design also affords the use of autofocus in the Focus Magnifier mode as well as improved focusing peaking to benefit manual focus operation.
  • 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.
  • A durable shutter unit incorporates a coreless motor and brake system that reduces vibrations to better control shutter shock as well as extend its rated lifespan to approximately 500,000 actuations.
  • Weather-sealing has been employed to resist dust and moisture for reliable operation in harsh weather conditions.
  • Using the same NP-FZ100 battery as the a9, the a7R III has improved battery life and is now rated for approximately 530 shots per charge with the EVF or 650 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. One of the card slots is rated to support UHS-II memory cards.
  • Integrated PC sync terminal for wired flash sync with strobe packs or wireless radio remotes.
  • A USB 3.1 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 III 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 III to instantly share imagery to mobile devices for direct sharing online to social networking, via email, and to cloud storage sites.
