    Photography Features

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


    Lens Mount

    OM System OM-1 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.

    Connectivity, Battery and Storage

    Built-in Wi-Fi

    Camera has a built-in Wi-Fi (Wi-Fi 5, 802.11ac/b/g/n, 2.4/5 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.

Camera can shoot continuously up to 120.0 fps with electronic shutter and up to 10.0 fps with mechanical shutter.


    Focusing

    OM System OM-1 has 1053 (1053 cross-type) focusing points and from -6 to +19 EV detection range. Touch-to-Focus allows 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. There is also face detection feature which automatically finds and focuses on faces and additional eye detection further locks the focus on one of the eyes and tracks it down during the motion.


    Exposure

    Camera's exposure metering ranges from -2 to +20 EV and you can set the exposure compensation within the ±5 EV range. You can also do exposure lock, exposure bracketing and manual exposure adjustment.


    Flash

    OM System OM-1 has no built-in flash but an external flash may be connected via Hot Shoe or PC Terminal. The fastest flash synchronization speed is 1/250 sec. Flash compensation can be set from -3 to +3 EV with 1/3 or 1/2 or 1 EV step increments.
