Electronic (OLED) Viewfinder on Olympus OM-D E-M10 Mark IV

Olympus OM-D E-M10 Mark IV has a built-in Electronic (OLED) viewfinder with 2,360k dot resolution. It has a 100% coverage and 1.23x (0.62x 35mm equivalent) magnification. There is no built-in or optional viewfinder available on Sony FX3.

Sony FX3 features a 10.2 megapixel Full Frame BSI-CMOS sensor with dimensions of 35.6 x 23.8 mm and a total area of 847.3 mm². Its native ISO range is 80 - 102,400 and expands to 50 - 409,600 in boosted mode. Olympus OM-D E-M10 Mark IV features a 20.3 megapixel Micro Four Thirds CMOS 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 100 - 25,600 in boosted mode.

Sony FX3 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.

Sony FX3 is equipped with BIONZ XR processor and can take pictures up to 4240 x 2832 resolution. Olympus OM-D E-M10 Mark IV is equipped with TruePic VIII processor and can take pictures up to 5184 x 3888 resolution.

Lens Mount

Sony FX3 has Sony E lens mount and Olympus OM-D E-M10 Mark IV has Micro Four Thirds lens mount. Due to Full Frame sensor in Sony FX3 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-M10 Mark IV 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) (4.5 stops of compensation in Olympus OM-D E-M10 Mark IV). 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.

Built-in Wi-Fi

Cameras have built-in Wi-Fi (Wi-Fi 5 802.11ac/b/g/n 2.4/5 GHz on Sony FX3, 802.11b/g/n 2.4 GHz on Olympus OM-D E-M10 Mark IV) 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.
