Pair it with premium glass for the best image quality

I'm a Canon shooter by trade, but one reason I'd be tempted to switch to Sony is their outstanding lineup of E-mount lenses.

Sony makes some of the best optical elements on the planet, and their E-mount lenses (especially their higher-end glass) are world-famous for their light-gathering abilities and quick, ultra-sharp focusing.

It's worth noting that this "body only" configuration of the Alpha a7R III A does not come with a lens in the box. Check out my article on choosing camera lenses to find the right one for you.

Clear Image Zoom: Clear Image Zoom, powered by Sony's By Pixel Super Resolution Technology, increases the effective focal length of the lens by up to 4x (Small images), 3.1x (Medium images), or 2x (Small images) by digitally magnifying the center of the image with no image degradation. A separate Digital Zoom of approximately 4x - 8x is also available, depending on the image size. For movies, Clear Image Zoom magnifies the image by approximately 1.5x for 4K and about 2x for HD movies.

Focus Modes: The α7RIII's Fast Intelligent auto focus system combines the high-speed BIONZ X image processor and improved algorithms with optimized image sensor read-out speed to provide ultra-fast auto focusing. You can choose from the following Auto/Manual Focus Modes:

  • AF-S (Single-shot Auto focus): The camera focuses and the focus is locked when you press the shutter button halfway down. Recommended for use with motionless subjects.
  • AF-A (Automatic Auto focus): The camera locks the focus when it determines that the subject is motionless, or continues to focus when the subject is in motion. During continuous shooting, the camera automatically shoots with Continuous AF from the second shot.
  • AF-C (Continuous Auto focus): The camera continues to focus while the shutter button is pressed and held halfway. Recommended for use when the subject is in motion.
  • Direct Manual Focus (DMF): After focusing automatically, you can make fine focusing adjustments manually by turning the focus ring on the lens.
  • Manual Focus: When it is difficult to get the proper focus in auto focus mode, you can adjust the focus manually. This mode allows you to set the distance of a subject by rotating the focusing ring to achieve a sharp focus.

AF (Auto focus) Area: The α7RIII features 399 focus points for phase-detection auto focusing in full frame mode with full frame lens. In APS-C mode it has 323 points with full frame lens and 255 points with APS-C lens. The camera has 425 contrast-detection focus points. You can select between 6 settings:

  • Wide: The camera focuses automatically on a subject in all ranges of the image.
  • Zone: You can select a zone on the monitor on which to focus.
  • Center: The camera uses the AF area located in the center area exclusively.
  • Flexible Spot: You can change the size of and move the focusing area in order to focus on a small subject or narrow area.
  • Expand Flexible Spot: If focus isn't possible on the single selected point, it uses focus points around the flexible spot as a secondary focus area to facilitate focus.
  • Lock-on AF: When the shutter button is pressed halfway, the camera tracks the subject within the select AF area. You can select the desired tracking start area by designating the area as a flexible spot or an expanding flexible spot.

Eye AF: The Eye AF function has been improved with two times more effective eye detection and tracking, even when shooting a moving portrait subject, or if the subject is looking down or away, or is backlit. When photographing your pet or wildlife, the Animal-eye AF automatically detects and tracks the eyes of animals. This feature is available with a software upgrade.

Face Detection: The camera can detect human faces, and adjusts the focus, exposure, performs image processing and adjusts flash settings for best results. Faces can be registered, and priority given to those faces over others in the frame. Up to 8 faces can be detected and/or registered.

AF Illuminator: When you press the shutter button halfway down a red illuminator is emitted until the focus is locked. Under dark lighting conditions or when you shoot a low contrast subject, the AF illuminator allows the camera to focus more easily on the subject. The AF illuminator has a range of 0.99' to 9.8' (with FE 28-70mm lens).

In-body Stabilization: The α7RIII is equipped with a sensor-shift-type in-body image stabilization system to reduce the effect of camera shake. This system is carefully fine-tuned to match the 42.4-megapixel performance of the camera, allowing you to photograph faraway objects without the blur of camera shake. It features 5-axis compensation with an effect equivalent to 5.5 stops faster shutter speed. It can compensate for camera shake in the following ways: pitch, yaw, X-axis, Y-axis, and roll.

Drive Modes: The camera offers the following shooting modes: Single shooting, Continuous Shooting, Self-timer, Self-timer Continuous, and Bracketing (continuous, single, white balance, and DRO).

Continuous Shooting: The camera can record still images continuously while the shutter release button is held down. You can select from the following speeds: Hi+ (10 fps), Hi (8 fps), Mid (6 fps), and Low (3 fps). The maximum number of recordable frames depends upon the image quality setting:

  • JPEG Large (Standard, Fine, or Extra Fine): 76 images
  • Compressed RAW and Compressed RAW+JPEG: 76 images
  • Uncompressed RAW and Uncompressed RAW+JPEG: 28 images

Self-Timer: You can set the camera to several self-timer settings:

  • 10 Second: After you press the shutter button, the shutter will be released about 10 seconds later. This is convenient when the photographer wants to appear in a photo.
  • 2 Second: After you press the shutter button, the shutter will be released about 2 seconds later. This is convenient to reduce camera-shake.
  • Continuous Self-timer: The camera records 3 or 5 images continuously after a 10, 5, or a 2 second delay. You can choose the best shot from the multiple shots taken.
  • Bracketing Self-timer: The camera records multiple images, each with a different exposure, after a 10, 5, or 2 second delay.

Bracket Shooting: Bracket shooting allows you to shoot 3 images, each with different degrees of exposure, white balance, flash intensity, and dynamic range. You can select the increment steps for each frame of the bracket.

Exposure Modes: The top-mounted Mode Dial lets you select from the following exposure modes:

  • iAuto (Intelligent Auto): This mode allows easy shooting with settings adjusted automatically using scene recognition.
  • Program Auto (P): For shooting with the exposure adjusted automatically (both the shutter speed and the aperture value), while allowing you to adjust other settings manually.
  • Aperture Priority (A): This mode allows you to shoot after adjusting the aperture value manually, letting the camera set the appropriate shutter speed. This mode gives you greater control over the depth of field.
  • Shutter Speed Priority (S): This mode allows you to shoot after adjusting the shutter speed manually, letting the camera set the appropriate aperture. You can choose a shutter speed of 1/8000 to 30 seconds for still images, or 1/8000 to 1/4 second for movies. With a high shutter speed, the moving subject appears as if it is frozen on the image. With a slow shutter speed, the moving subject appears as if it were flowing. Bulb photography is also available in this mode.
  • Manual Exposure (M): This mode allows you to shoot after adjusting the exposure (shutter speed and aperture) manually.
  • Memory Recall (1, 2, 3): You can register often-used camera settings (including Shooting Mode, Aperture, Shutter speed) in one of three memory positions on the Mode Dial for easy recall.
  • Movies: You can record movies in 4K, Full HD, or standard definition in 16:9 or 4:3 aspect ratio. When selected on the Mode Dial, you can select the desired movie settings, including Program Auto, Aperture Priority, Shutter Priority, and Manual Exposure.

Metering Mode: A 1200-zone evaluative sensing system provides multi-pattern measuring for superior exposure control accuracy in a wide range of lighting conditions. You can select the method for measuring the brightness of a subject from the following methods:

  • Multi Segment: This method uses the whole screen divided into 1200 zones to measure light.
  • Center Weighted: While emphasizing the central area of the screen, this method measure the average brightness of the entire screen.
  • Spot: This method measure light only in the spot metering circle in the center of the frame.
  • Entire Screen Average: Measures the average brightness of the entire screen.
  • Highlight: Measures the brightness while emphasizing the highlighted area on the screen.

White Balance: You can adjust the color tones according to the lighting conditions.
