  • General
    • Brand: Sony
    • Model Number: ILCE7RM3/B
    • Product Name: Alpha a7R III Full-Frame Mirrorless 4k Video Camera (Body Only)
    • Color: Black
    • Camera Model Family: Sony a7R III
    • Digital Camera Type: Mirrorless Camera Body Only
  • Imaging
    • Image Sensor Type: CMOS (CCD and CMOS are the two main technologies used in image sensors. CCD, the older of the two types, turns analog light signals into digital pixels. This conversion happens without distortion, resulting in high-quality images. Newer CMOS sensors use transistors at each pixel to move electrical charges. CMOS sensors are typically less expensive, but also require more light to create distortion-free images.)
    • Image Sensor Size: 35mm Full Frame (36 x 24 mm)
    • Total Pixels: 44 megapixels (Generally, the more pixels, the higher the image resolution and the finer the detail that can be seen.)
    • Image Resolution (Display): 3840 x 2160 (Refers to the number of pixels, both horizontally and vertically, used to either capture an image or display it. The higher the resolution the finer the image details.)
    • Zoom Capability: false (This function allows for magnification of the subject.)
    • Digital Zoom: 4x (A digital zoom is accomplished electronically, with no adjustment of the camera's optics, and no optical resolution gained in the process. The existing data is not enhanced or added to, merely displayed at a lower resolution, thereby giving an illusion of an enlarged image.)
    • In-Camera Image Stabilization: true (This feature helps reduce image blurring from camera motion. In-camera stabilization means the image sensor itself moves to counteract detected motion.)
    • Low Light/High Sensitivity: true (High sensitivity digital imaging devices are designed to work in low light conditions to produce a high dynamic range image.)
    • Image File Format(s): JPEG, RAW (Standardized software format(s) of storing digital images. The type of format chosen for capturing and compressing the image can determine quality, level of detail, and storage space required.)
  • Focus
    • Autofocus: true (Allows the camera to automatically focus through the lens, rather than by adjusting the lens manually.)
    • Eye Autofocus (Eye AF): true (Automatically seeks out and focuses on the subject's eye and holds it as the camera and subject move and as the photographer shoots at high frame rates.)
  • Exposure Control
    • Shutter Speeds: Still images: 1/8000 to 30 sec, Bulb; Movies: 1/8000 to 1/4 (1/3 steps); up to 1/60 in AUTO mode (up to 1/30 in Auto slow shutter mode) (The length of time the shutter remains open when the shutter release is activated, expressed in fractions of seconds. The longer the shutter is open, the more light that is able to be captured by the camera sensor.)
    • Brightness Control: true (Allows the camera to adjust the brightness of a captured image for optimal exposure.)
    • Burst Mode: true (Also referred to as continuous shooting. This feature captures multiple shots in rapid succession.)
    • Burst Rate: 5 frames per second
    • Self Timer: true
    • Shooting Modes: AUTO (iAuto), Programmed AE (P), Aperture priority (A), Shutter-speed priority (S), Manual (M), Movie modes (Exposure modes employed by the photographer to control the optimal aperture, shutter speed, ISO, and other settings for capturing specific subjects/scenes. Examples include Aperture-Priority, Macro, and Manual modes.)
    • Panorama Mode: false
    • Scene Modes: Auto, Programmed AE, Aperture priority, Shutter-speed priority, Manual, Movie, Slow & quick motion (Exposure modes with predetermined optimal settings for capturing specific scenes. Examples include Landcape, Portrait, and Sports modes.)
    • White Balance Modes: Auto, Daylight, Shade, Cloudy, Incandescent, FluorescentWarm White, Cool White, Day White, Daylight, Flash, Underwater, Color Temperature, Color filter, Custom (Settings that calibrates how the color white is rendered in an image/video, reducing the appearance of unnatural contrasts caused by various light sources.)
    • Effective Pixels: 42.4 megapixels (The actual number of pixels which make up the viewable image.)
  • Lens
    • Lens Mount Compatibility: Sony E-Mount, Sony E-Mount (Full-Frame)
    • In-Lens Image Stabilization: false (This feature helps reduce image blurring from camera motion. Lens stabilization means an element within the lens moves automatically to counteract detected motion.)
  • Flash
    • Integrated Flash: false
    • External Flash Mount: Hot Shoe (A cold shoe is a mounting point on top of a camera to securely attach a flash unit or other compatible accessories. A hot shoe is a cold shoe with an electrical connection that insures communication and synchronization between camera and accessory.)
  • Display
    • Display Type: TFT-LCD
    • Screen Size: 2.95 inches (Size of the screen, measured diagonally from corner to corner.)
    • Screen Resolution: 1,440,000 dots (Screens come in a range of resolutions (measured in pixels, horizontal x vertical). The higher the resolution, the greater the picture quality.)
    • Viewfinder Type: Electronic (A viewfinder is the part of a camera (or attachment) that allows you to see and focus a scene in frame. Optical viewfinders let you view the scene directly through the lens. Electronic viewfinders display the image on a screen in its approximate final form.)
    • Touch Screen: true (Touch-screen devices make navigating more intuitive. Using a touch-screen display, you can do things such as tap to select, hold and drag to move items, swipe to scroll, and pinch to zoom.)
    • Varying Angle Screen: true (The camera's screen can be flipped out and adjusted to rotate, tilt, and/or swivel.)
  • Video
    • Standardized Video Resolution: 4K (2160p) (An approximated measurement of the product’s video resolution. This may not be the exact resolution of the product, which may be slightly more or less when using a pixel-by-pixel measurement.)

Q: Does this camera have HDR mode?

A: Yes, this camera has HDR mode.

Q: How many memory card slots does this camera have?

A: This camera has two memory card slots.

Q: I can't figure out the difference between Alpha a7 III and Alpha a7R III. I would greatly appreciate any input anyone might have. Thanks!

A: The A7III has a 24mp sensor with 693 autofocus points. The A7RIII has a 42 mp sensor with 425 autofocus points. The A7III may perform slightly better in low light at higher ISOs than the A7RIII. The A7RIII has pixel-shift multi-shoot mode for added sharpness and detail when shooting still objects, etc. If you need the ultimate in resolution and plan to create very large photos, the A7RIII has the pixels to do so. If you aren't interested in the ultra-high image size but want a very versatile camera, the A7III is amazing.

    Went mirrorless

    So far, this is a GREAT CAMERA. I have much to learn but , being a long term Sony camera user, I am finding it relatively easy. It is just so much lighter to carry and the A mount to E mount converter is letting me use my array of lenses. I am very happy that I purchased this camera and recommend it for professional work. The 42 megapixel sensor is great.

    BEST MIRRORLESS UNDER 3000 DOLLARS

    Best camera under $3k BARNONE. I photograph motorcycles and this camera has everything I need and nothing I don’t need. What isn’t there to like about this camera? It has 42megapixels, it does 10fps burst, it has tracking AF, more than enough AF points, it has a long lasting battery. I couldn’t be anymore happy with it. This camera will be my main body for a long time and then a backup when I upgrade.
