Canon EOS 5DS R is equipped with Dual DIGIC 6 processor and can take pictures up to 8688 x 5792 resolution. Pentax K-1 Mark II is equipped with PRIME IV processor and can take pictures up to 7360 x 4912 resolution.

Lens Mount

Canon EOS 5DS R has Canon EF lens mount and Pentax K-1 Mark II has Pentax K_AF4 lens mount. Due to their Full Frame sensor their crop factor (also called lens multiplier) is equal to 1x. This means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length.

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 Pentax K-1 Mark II

Pentax K-1 Mark II has a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS) with 5 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 GPS on Pentax K-1 Mark II

Pentax K-1 Mark II has a built-in GPS (Global Positioning System) technology which allows you to automatically tag the location where you took your photos. You can later categorize, organize, and search for photos based on location. This is very useful for travel and outdoor photographers for documenting the locations where images were captured.
