We already listed pros and cons of each model. However, you may also find useful to look at their common strengths and weaknesses shown side-by-side.

Screen

Nikon Z8 has a 3.2" screen with 2,100k dot resolution and Olympus OM-D E-M10 Mark IV has a 3.0" screen with 1,040k dot resolution. Both have Tilting screens. Tilting screen makes cameras very useful for photography purposes but not so 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

Nikon Z8 has a built-in 0.5" Electronic (OLED) viewfinder with 3,690k dot resolution and Olympus OM-D E-M10 Mark IV has a built-in Electronic (OLED) viewfinder with 2,360k dot resolution. They both have 100% coverage.

Nikon Z8 features a 45.7 megapixel Full Frame Stacked CMOS sensor with dimensions of 35.9 x 23.9 mm and a total area of 858 mm². Its native ISO range is 64 - 25,600 and expands to 32 - 102,400 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.

Nikon Z8 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.

Nikon Z8 is equipped with EXPEED 7 processor and can take pictures up to 8256 x 5504 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

Nikon Z8 has Nikon Z lens mount and Olympus OM-D E-M10 Mark IV has Micro Four Thirds lens mount. Due to Full Frame sensor in Nikon Z8 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.

No Low-Pass Filter on Nikon Z8

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on Nikon Z8. This results in a slightly sharper image but may also introduce moiré patterns and aliasing artifacts when photographing subjects with fine, repetitive patterns or details.

In-Body Image Stabilization

The cameras have a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS) (6 stops of compensation in Nikon Z8 and 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 Nikon Z8, 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.
