Canon EOS 5DS R is equipped with Dual DIGIC 6 processor and can take pictures up to 8688 x 5792 resolution. OM System OM-1 is equipped with TruePic X Dual Quad processor and can take pictures up to 5184 x 3888 resolution.

Lens Mount

Canon EOS 5DS R has Canon EF lens mount and OM System OM-1 has Micro Four Thirds lens mount. Due to Full Frame sensor in Canon EOS 5DS R 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 OM System OM-1 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

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