      Screen and Viewfinder

      Screen

      Sony Alpha 1 and Olympus OM-D E-M5 Mark III have 3.0" screens with 1,440k dot and 1,040k dot resolutions respectively. Sony Alpha 1 has a Tilting screen which makes it very useful for photography purposes but not so useful for video shooting. Olympus OM-D E-M5 Mark III has a Fully Articulated screen which makes it selfie and vlogger friendly and generally very useful for video shooting. Both models feature touchscreen which has advantages such as easy menu navigation, intuitive controls, quick setting adjustment and most importantly a Touch-to-Focus functionality allowing users to select a specific point on the screen where they want the camera to focus. This feature can be helpful for achieving precise focus in both photo and video recording.

      Viewfinder

      Sony Alpha 1 has a built-in 0.64" Electronic (OLED) viewfinder with 9,437k dot resolution and Olympus OM-D E-M5 Mark III has a built-in Electronic (OLED) viewfinder with 2,360k dot resolution. They both have 100% coverage.

      Sensor

      Sony Alpha 1 features a 50.1 megapixel Full Frame Stacked CMOS sensor with dimensions of 35.9 x 24 mm and a total area of 861.6 mm2. Its native ISO range is 100 - 32,000 and expands to 50 - 102,400 in boosted mode. Olympus OM-D E-M5 Mark III features a 20.4 megapixel Micro Four Thirds MOS sensor with dimensions of 17.4 x 13 mm and a total area of 169 mm2. Its native ISO range is 200 - 25,600 and expands to 64 - 25,600 in boosted mode.

      Sony Alpha 1 has Stacked CMOS sensor. The key feature of such sensor is its three-dimensional structure, which consists of multiple layers of semiconductor material and circuitry stacked on top of each other. This allows the sensor to have dedicated layers for image capture and signal processing. This separation allows for faster data readout, reducing rolling shutter effects and enabling high-speed shooting and video recording. It is also more power-efficient.

      Photography Features

      Sony Alpha 1 is equipped with Dual BIONZ XR processor and can take pictures up to 8640 x 5760 resolution. Olympus OM-D E-M5 Mark III is equipped with TruePic VIII processor and can take pictures up to 5184 x 3888 resolution.


      Lens Mount

      Sony Alpha 1 has Sony E lens mount and Olympus OM-D E-M5 Mark III has Micro Four Thirds lens mount. Due to Full Frame sensor in Sony Alpha 1 its crop factor is equal to 1x, this means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length. Due to Micro Four Thirds sensor in Olympus OM-D E-M5 Mark III its crop factor is equal to 2x, this means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 2.


      In-Body Image Stabilization

      The cameras have a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS) (5.5 stops of compensation in Sony Alpha 1 and 6.5 stops of compensation in Olympus OM-D E-M5 Mark III). This means that you are still getting vibration reduction when cameras are paired with non-image stabilizied lenses. It also works with lenses with optical image stabilization and in combination can achieve even better compensation.

      Connectivity, Battery and Storage

      Built-in Wi-Fi

      Cameras have built-in Wi-Fi (Wi-Fi 5 802.11ac/b/g/n 2.4/5 GHz on Sony Alpha 1, 802.11a/b/g/n 2.4 GHz on Olympus OM-D E-M5 Mark III) which allows to easily transfer photos and videos from the camera to other Wi-Fi-enabled devices, such as smartphones, tablets, printers, or computers. This eliminates the need for cables and allows for quick and convenient media sharing and social media integration. It gives you the ability to control your camera remotely using a smartphone or tablet. This is particularly useful for taking self-portraits, group shots, or capturing images in challenging conditions without having to touch the camera. Firmware updates can also be downloaded and installed wirelessly.
