    Photography Features

    Camera is equipped with TruePic IX processor and can take pictures up to 5184 x 3888 resolution.


    Lens Mount

    Olympus OM-D E-M1 Mark III has Micro Four Thirds lens mount. Due to Micro Four Thirds sensor its crop factor (also called lens multiplier) is 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

    There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor. 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 camera has a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS) with 7 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.
