About the Sony Alpha a7S III (no lens included)

Kramer Crane

Ultra-sharp in low-light

Sony is legendary for the phenomenal image quality their mirrorless cameras offer — especially in low-light environments. The Alpha a7S III is no exception, delivering stunning photos and videos indoors and out. 

Ultra-sharp in low-light

Sony is legendary for the phenomenal image quality their mirrorless cameras offer — especially in low-light environments. The Alpha a7S III is no exception, delivering stunning photos and videos indoors and out. 

Advanced features like dual memory card slots, in-body image stabilization, and a spectacular autofocus system help ensure top performance for creative enthusiasts and working professionals alike.

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 does not come with a lens in the box. Check out my article on choosing camera lenses to find the right one for you.

Recording Features

Overview: The Sony α7S III (ILCE-7SM3) Alpha-series camera kit contains the α7S III camera body, along with a rechargeable battery, battery charger, neck strap, and USB cable. The α7S III has a 12.1 mega-pixel full-frame 35mm image sensor, and is compatible with Sony E-mount lenses. With the LA-EA4 Mount Adapter, the camera can also use Sony A-mount lenses. (No lenses are included in this "body only" kit.)

3" Vari-angle LCD Screen: The α7S III uses a 3" Vari-angle LCD screen with 1,440,000 dots. You can open the LCD up approximately 176° and rotate up to 180° and down by 90°. The bright LCD monitor features a touch-sensitive panel with convenient Touch Focus and Touch Tracking functions. Sony's new menu struction is more intuitive, making it easier to change camera settings. The brightness of the LCD monitor can be adjusted in 5 steps from -2 to +2, plus a Sunny Weather mode.

0.64" OLED Electronic Viewfinder: The 0.64" Quad-XGA OLED electronic color viewfinder has 9,437,184 dots and 100% of coverage. It has a magnification of 0.90x and a wide 41° field of view (FOV) for full frame mirrorless cameras. In the Viewfinder/Monitor menu, you can switch to a special "Zoom Out" mode that provides a 33° FOV, equivalent to an APS-C camera view. It has a -4.0 to +3.0m-1 diopter adjustment to focus the viewfinder to your eyesight. The Finder Frame Rate can be switched between 60fps (standard) and 120fps (Hi). You can set the camera to switch between the LCD screen and viewfinder automatically when you look into the VF, or manually choose one or the other in the camera's menu.

Display Options: The Display Setting (DISP) button lets you choose how much information appears in the viewfinder and LCD monitor. During shooting using the LCD monitor, the options are Display All Info, No Display Info, Histogram, Digital Level Gauge, and For Viewfinder. During Shooting using the viewfinder, you can choose from Digital Level Gauge, Histogram, and No Display info. During playback, using either the monitor or viewfinder, you can cycle between: Display Info, Histogram, and No Display Info.

Live View: The α7S III's Live View lets you use the LCD screen and Electronic Viewfinder to frame your photos as you shoot. When the Live View display is set to "Setting Effect On", the LCD or viewfinder will provide an accurate preview of your photo, including the white balance, exposure compensation, creative style or picture effect. With the "Setting Effect Off", you can check the image composition without the effects of the exposure settings.

SteadyShot INSIDE: The α7S III is equipped with In-body Image Stabilization with an image sensor-shift mechanism. SteadyShot INSIDE provides 5-axis compensation to reduce image blur caused by camera shake from five different directions: vertical, horizontal, pitch, yaw, and roll. The compensation effect is equal to approximate 5.5 stops. When recording still images, you can turn Image Stabilization on or off. For movies, you can choose between Active, Standard, or off. In-body Image Stabilization works with a wide range of E-mount and A-mount lenses (with mount adapter) that do not include stabilization of their own. Using lenses with Optical SteadyShot provides the maximum amount of compensation.

Image Sensor: The α7S III features an advanced 12.1-megapixel, Exmor R full-frame 35mm CMOS image sensor (35.6 x 23.8mm). It has approximately 12.9-million total pixels and 12.1-million effective pixels. The sensor's larger pixels and doubled sensor readout speed, combined with Sony's new BIONZ XR™ image processor, results in maximum sensitivity and dynamic range, faster processing and auto focus, and the ability to record 10-bit 4:2:2 4K movies at up to 120p.

Still Image Recording Formats: The α7S III can shoot JPEG, RAW, and HEIF (High Efficiency Image File) still images. Full-frame JPEG and HEIF images are recorded in Extra Fine, Fine, and Standard compression rates, and three sizes (L, M, S). RAW images are recorded in Compressed or Uncompressed formats in Large size only. For the first time in an α-series camera, the α7s III supports 16-bit RAW data output to an external recorder via HDMI (4264 x 2408 16:9 aspect ratio) with a choice of frame rates. RAW images must be transferred to a computer for processing, editing, and printing using the downloadable Imaging Edge software. Images can also be recorded in an APS-C-equivalent size. You can choose from 3:2, 16:9, 4:3, or 1:1 aspect ratios. You can select the following image sizes:

  • Sort (Still image/movies): Still images are recorded to the memory card in the slot you select in the menu. Movies are recorded to the other memory card.
  • Auto Switch: If the memory card in use becomes full, the camera automatically switches to the other memory card.

NTSC/PAL: The camera lets you store both NTSC and PAL formatted video files on the same memory card. This eliminates the need for having separate memory cards for the two video formats.

Fast Hybrid Focusing: The α7S III's new Fast Hybrid AF system features 759 phase detection points in a high-density focal plane phase-detection system, covering approximately 92% of the image area. The phase detection focus points work with the 425 contrast detection AF points in the Fast Hybrid auto focus system to give you lightning fast auto focusing and superb real-time tracking capability.

Real-time Tracking: The camera's Real-time Tracking feature uses artificial intelligence to track moving subjects when shooting still images and movies. The camera maintains accurate focus while the shutter button is pressed halfway until you take the shot. Touch Tracking lets you select your subject by touching it on the touch-screen monitor. If the subject is a person, the AI detects and tracks the subject's eye and face in real time for sharp portraits. You can select the left or right eye in the menu. There's even an Eye AF Animal mode to track the eye of your pet.

Focus Modes: You can choose from the following Focus Modes:

  • AF-S (Single-shot AF): 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 AF): Single-shot and Continuous AF are switched according to the movement of the subject. If the subject is motionless, the camera locks the focus. If the subject is in motion, the camera continues to focus.
  • AF-C (Continuous AF): The camera continues to focus when you press and hold the shutter button halfway down. Recommended for use when the subject is in motion.
  • DMF: After focusing automatically, you can make fine focusing adjustments manually (Direct Manual Focusing).
  • 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: You can choose between the following settings:

  • Wide: The camera focuses automatically on a subject in all ranges of the image.
  • Zone: You can select a zone (consisting of 9 focus areas) on the monitor on which to focus.
  • Center Fix: The camera uses the AF area located in the center area exclusively.
  • Spot (S/M/L): You can change the size of and move the focusing area in order to focus on a small subject or narrow area.
  • Expand Spot: If you cannot focus on a single selected point, you can use focus points around the flexible spot as a secondary priority area for focusing.
  • Tracking: When the shutter button is pressed halfway, the camera tracks the subject within the selected autofocus area. The Focus Mode must be set to Continuous AF.

Eye AF: The new Eye AF function can be assigned to a customizable button. When Eye AF is selected, the camera focuses on a person's eyes for extremely sharp focusing of the face.

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.

Focus Lock: If a subject is off-center and outside of the AF area, you can lock the focus of the camera.

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.

Custom Zoom Settings: When using a compatible powered zoom lens, the camera lets you customize certain settings to suit your personal preferences and shooting style. You can choose the direction of the zoom ring, and assign custom buttons for zoom in and zoom out functions. There are 8 selectable zoom speeds that can be independently set for recording and standby modes. This lets you set a slow zoom speed for recording, and a fast zoom speed when you're not recording.

Drive Modes: The camera offers the following shooting modes:

  • Single Shooting: Default setting for standard picture taking.
  • Continuous Shooting: You can take photos continuously while the shutter button is held down. In Hi+ Continuous Shooting mode, images are shot continuously at the maximum speed (at approximately 10 fps) while you press and hold down the shutter button. The Hi (8 fps), Mid (6 fps), and Lo (3 fps) Continuous shooting modes make it easier to track, because the subject is displayed in real time on the monitor/viewfinder during shooting.
  • Self-Timer: You can set the camera to four different self-timers:
    • 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.
    • 5 Second: After you press the shutter button, the shutter will be released about 5 seconds later. This is convenient when the photographer wants to appear in the 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: The camera records 3 or 5 images continuously after a pre-selected delay of 10, 5, or 2 seconds. You can choose the best shot from the shots taken.
  • Bracket Shooting: The camera is capable of shooting multiple images, each with a different setting. You can choose from the following Bracket options:
    • Continuous Bracket: Shoot 3 or 5 images, each with different degrees of brightness (0.3EV, 0.5EV, 0.7EV, 1.0EV, 2.0EV or 3.0EV). The images are taken as you press and hold the shutter button.
    • Single Bracket: Same as Continuous Bracket above, except that the shutter button is pressed for each image.
    • WB Bracket: The camera records three images, each with different color tones, according to the selected settings of white balance, color temperature, and color filter. You can select Low (small changes in white balance) or High (large changes in white balance).
    • DRO Bracket: The camera records three images, each with different degree of D-Range Optimizer. You can select Low (small changes in DRO) or High (large changes in DRO).

Shooting Modes: The top-mounted Mode Dial lets you select from the following shooting modes:

  • iAuto (Intelligent Auto): This mode allows easy shooting with settings adjusted automatically.
  • Program Auto: 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: 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 Priority: This mode allows you to shoot after adjusting the shutter speed manually, letting the camera set the appropriate aperture. 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.
  • Manual Exposure: 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 or Full HD in 16:9 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.
  • S&Q Motion: This mode lets you shoot slow-motion and quick-motion movies.

Silent Shooting: In addition to the camera's mechanical shutter, the α7S III is equipped with an electronic shutter which has no moving parts. Using the electronic shutter, you can capture images in total silence and without vibration. This is particularly helpful when recording animals or sleeping babies.

Exposure Compensation: Exposure compensation is used to alter the camera's standard exposure setting. You can make the image look lighter (increased exposure) or darker (decreased exposure) The exposure compensation amount can be set up to +/-3.0 EV in 1/3-step increments by turning the dial on the top of the camera or +/-5.0 EV in 1/3-step or 1/2-step increments in the menu. When shooting movies, the exposure can be adjusted in a range of +/-2.0 EV.

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 five methods:

  • Multi: This method uses the whole screen divided into 1200 zones to measure light.
  • Center: 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. You can choose from the following WB options: Auto WB, Auto: Ambience, Auto: White, Daylight, Shade, Cloudy, Incandescent, Fluorescent (Warm White), Fluorescent (Cool White), Fluorescent (Day White), Fluorescent (Daylight), Flash, Underwater Auto, Color Temperature, Color Filter, and Custom (1, 2, 3).

Color Temperature/Color Filter: You can adjust the white balance further by selecting Color Temperature or Color Filter in the Custom White Balance option. With Color Temperature, the higher the number, the more reddish the image, and the lower the number, the more bluish the image.
