RENTAL ONLY - Sony Alpha a7R III Mirrorless Camera Body

The Sony Alpha a7R Mark III combines resolution, faster auto focus and processing speeds, along with 4K and HDR video capabilities to create the perfect camera for the do-it-all photographer.

42.4 Megapixel Full-Frame Resolution and Processing Power

The 42.4MP high-resolution, back-illuminated Exmor R CMOS sensor utilizes a gapless on-chip lens design and AR (anti-reflective) coating on the surface of the sensor's seal glass to dramatically improve light collection efficiency. This results in high sensitivity with low-noise performance and wide 15-stop4 dynamic range. No optical low pass filter maximizes resolution, while also having the ability to output 14 bit RAW15 format even when shooting in silent or continuous mode. Nothing less than spectacular images.

The a7R III features a new front-end LSI that effectively doubles* the readout speed of the image sensor, as well as an updated BIONZ X processing-engine that boosts processing speed by approximately 1.8 times compared to the a7R II. These powerful components work together to allow the camera to shoot at faster speeds while also enabling its impressive ISO range of 100 - 32000 (expandable to ISO 50 – 102400 for still images) and massive 15-stop4 dynamic range at low sensitivity settings. This ensures outstanding overall performance at all settings and in all shooting conditions.

The Need for Speed, Up to 10 FPS and Hybrid AF System

The a7R III is equipped with a refined image processing system that allows it to capture full 42.4MP images at up to 10 fps with continuous and accurate AF/AE (autofocus and auto exposure) tracking for up to 76 JPEG / RAW images or 28 uncompressed RAW images. This high speed 10 fps mode is available with either a mechanical shutter or an electronic shutter for completely silent shooting, adding to the immense flexibility of the camera. The a7R III can also shoot continuously at up to 8 fps in live view mode with minimal lag in the viewfinder or LCD screen. 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 a7R III is comprised of 399 focal-plane phase-detection AF points that cover approximately 47% of the image area in both the horizontal and vertical directions and 425 contrast AF points which cover approximately 68% of the image area (an increase of 400 points compared to the a7R II). When combined, both contrast and phase detection AF points form the hybrid AF system for wide, fast, reliable AF that locks on and stays locked on. This advanced system delivers AF acquisition in about half the time as the a7R II in low-light conditions with tracking that is approximately 2 times more accurate as well. The acclaimed Eye AF feature is also approximately twice as effective, and is available when utilizing Sony's A-mount lenses with an adapter.

The camera features a multi-selector joystick on the back of the camera, allowing shooters to easily shift focus within the frame by pressing the multi-selector in any direction up, down, left or right when shooting in Zone, Flexible Spot or Expanded Flexible Spot focus area modes.

Controls are refined for intuitive operation and immediate adjustment even while looking through the viewfinder. The α9 features front and rear dials for easier, more efficient handling and turning. A mode dial locking mechanism prevents inadvertent changes of shooting mode at all times and a stacked independently operable dials allow fast selection of drive and focus modes. Quickly select the single or continuous drive mode, or the single AF or continuous AF focus mode, for example, without having to scroll through menus. Both dials are lockable, preventing unwanted mode changes during use.

Shooting Steady with 5.5 Step, 5 Axis In-Body Stabilization

The 5-axis in-body SteadyShot image stabilization system has been fine-tuned to support high-resolution shooting capacity, resulting in the world's highest compensation performance for an image stabilization system at 5.5 step shutter speed advantage. Camera shake is effectively compensated on 5 axes: pitch and yaw that have the largest overall impact on image quality; X and Y shift that is most apparent at high magnification, and roll that can ruin night shots and movies. Stabilization is applied to the live-view image, making it easier to frame fast-moving subjects. Effective stabilization is provided for movies as well as stills, and for A-mount lenses attached via a mount adapter.

Thanks to a new shutter unit with a fast-response coreless motor and a brake system, front and rear curtain mechanical shutter vibrations that can cause blur, is subdued to a minimum, while allowing high-speed continuous shooting at up to 10 frames per second. The shutter is also quiet, and has been tested for durability in excess of 500,000 shutter cycles. Low-vibration high-reliability shutter helps to maximize 42.4 effective megapixel performance and enables 10 frame per second shooting with high speed studio strobes.

Video on the Full Frame, 4K HDR Video

The a7R III is exceptionally capable as a video camera, offering 4K (3840x2160 pixels) video recording across the full width of the full-frame image sensor. When shooting in Super 35mm format, the camera uses full pixel readout without pixel binning to collect 5K (15-megapixels) of information, oversampling it to produce high quality 4K footage with exceptional detail and depth. Both S-Log2 and S-Log3 are available for increased color grading flexibility, while HLG (Hybrid Log-Gamma) is included to support an Instant HDR (High Dynamic Range) workflow, allowing HDR (HLG) compatible TV's to playback beautiful, true-to-life 4K HDR imagery. The a7R III can also record Full HD at 120 fps at up to 100 Mbps*, allowing footage to be reviewed and eventually edited into 4x or 5x slow motion video files in Full HD resolution.

4K HDR (High Dynamic Range) astonishes viewers with visual depth and impact that are less like conventional movies and television – and more like real life. With the ability to reproduce images from deep shadows to piercing highlights, 4K High Dynamic Range (HDR) is astonishing. With Instant HDR, a first in palm-sized cameras, the a7R III empowers you to capture High Dynamic Range without complex post production. Hybrid Log-Gamma (HLG) recording captures HDR, yet plays back beautifully on both HDR and conventional televisions. For added versatility, the camera also provides S-Log3 encoding.

A Body That's Built to Last

The a7R III body construction features a lightweight, high-rigidity magnesium alloy for the internal frame as well as the top, front, and rear covers. The grip area has also been reinforced with an integrated magnesium alloy grip and front cover. The number of screws securing the lens mount has been increased to six in order to maximize rigidity and durability even when using heavy telephoto lenses. Sealing is provided throughout the body to minimize dust and moisture ingress, allowing it to function reliably in challenging environments. All major buttons and dials are provided with seals, while media and jack covers and enclosure edges feature tongue-and-groove joints for double protection. Maximum dust and moisture resistance is maintained at lens, vertical grip, and flash unit joints too, providing excellent system reliability.

Professional, In-Camera Work Flow

Rating and protect functions facilitate on-location sorting. Star ratings (1 to 5 stars) can be applied to still images right from the camera controls. The same ratings are maintained when the images are imported into PlayMemories Home or Imaging Edge software running on a PC. The rating function can be assigned to a custom button so that ratings can be applied via the review playback display. There is also a protect function that can prevent accidental erasure of images. The protect function can be assigned to a custom button (C3 is the default) so that images can be quickly protected during review. Ratings and protection can be applied via the review playback display on location or while traveling to save time.

Make it your own with easy button customization. A new My Menu feature allows up to 30 menu items to be registered for instant recall when needed. The registered items can be arranged in any convenient order, and unused items can be erased as required. The primary menus have also been reorganized for smoother search and operation. In addition, You can assign any of 72 functions to any of 11 customizable buttons as you like. This makes operation more intuitive, quick and easy, and is extra-convenient for accessing such functions as starting and stopping of movie recording and switching between viewfinder and monitor.
