Olympus OM-D E-M10 Mark III is equipped with TruePic VIII processor and can take pictures up to 4608 x 3456 resolution. Olympus OM-D E-M10 Mark II is equipped with TruePic VII processor and can take pictures up to 4608 x 3456 resolution.

Lens Mount

Cameras have Micro Four Thirds lens mount. Due to their Micro Four Thirds sensor their crop factor (also called lens multiplier) 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). 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 (802.11b/g/n, 2.4 GHz) 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.
