    Screen and Viewfinder

    Tilting Touchscreen

    Sony Alpha 7 III has a 3.0" Tilting touchscreen with 922k dot resolution. Tilting screen makes this camera very useful for photography purposes but not so useful for video shooting.

    Electronic Viewfinder

    Camera has a built-in 0.5" Electronic viewfinder with 2,359k dot resolution. It has a 100% coverage and 0.78x magnification.

    Sensor

    BSI-CMOS Sensor

    Sony Alpha 7 III features a 24.2 megapixel Full Frame BSI-CMOS sensor with dimensions of 35.8 x 23.8 mm and a total area of 852 mm2. Its native ISO range is 100 - 51,200 and expands to 50 - 204,800 in boosted mode.

    The camera has BSI-CMOS sensor, short for Backside Illuminated Complementary Metal-Oxide-Semiconductor sensor. In traditional CMOS sensors, the wiring and circuitry are located on the front side of the sensor, which can block some of the incoming light. BSI technology flips this design by placing the photosensitive elements (pixels) on the backside of the sensor, allowing more light to reach the pixels. This significantly enhances light sensitivity and improves low-light performance. BSI-CMOS sensors are particularly effective in low-light conditions, as they can capture more light, resulting in brighter and less noisy images. This makes them well-suited for indoor and night photography. BSI-CMOS sensors deliver a higher SNR and reduced cross-talk.

    Photography Features

    Camera is equipped with BIONZ X processor and can take pictures up to 6000 x 4000 resolution. It can also take pictures with lower resolutions like 6000 x 3376, 3936 x 2624, 3936 x 2216, 3008 x 1688, 3008 x 2000 with 3:2, 16:9 aspect ratios.


    Lens Mount

    Sony Alpha 7 III has Sony E lens mount. Due to Full Frame sensor its crop factor (also called lens multiplier) is 1x. This means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length.


    In-Body Image Stabilization

    The camera has a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS) with 5 stops of compensation. This means that you are still getting vibration reduction when camera is paired with non-image stabilizied lenses. It also works with lenses with optical image stabilization and in combination can achieve even better compensation.
