Pentax K-50 is equipped with PRIME M processor and can take pictures up to 4928 x 3264 resolution. It can also take pictures with lower resolution like 4224 x 2816, 3456 x 2304, 2688 x 1792 with 3:2 aspect ratios.

Lens Mount

Canon EOS R100 has Canon RF lens mount and Pentax K-50 has Pentax K_AF2 lens mount. They both have APS-C sensor but because of a small size difference their crop factors (also called lens multiplier) differ from each other. Canon EOS R100 has the crop factor of 1.6x which means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 1.6. Pentax K-50 has the crop factor of 1.5x which means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 1.5.

No Low-Pass Filter on Canon EOS R100

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on Canon EOS R100. 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-50

Pentax K-50 has a built-in Sensor Shift in-body image stabilization (IBIS). 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.
