It can also take pictures with lower resolution like 4000 x 3000, 4000 x 2672, 4000 x 2248, 2992 x 2992, 2816 x 2112, 2816 x 1880, 2816 x 1584, 2112 x 2112, 2048 x 1536, 2048 x 1360, 1920 x 1080, 1600 x 1200, 1600 x 1064, 1600 x 904, 1504 x 1504 with 1:1, 4:3, 3:2, 16:9 aspect ratios. OM System OM-1 is equipped with TruePic X Dual Quad processor and can take pictures up to 5184 x 3888 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.

No Low-Pass Filter on OM System OM-1

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on OM System OM-1. 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 on OM System OM-1

OM System OM-1 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.

Built-in Wi-Fi on OM System OM-1

OM System OM-1 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.
