Lens Mount

Canon EOS Rebel XS has Canon EF/EF-S lens mount and Pentax KF 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 Rebel XS 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 KF 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 Pentax KF

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

Pentax KF has a built-in Sensor Shift in-body image stabilization (IBIS) with 4.5 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 Wi-Fi on Pentax KF

Pentax KF has a built-in Wi-Fi (802.11b/g/n, 2.4 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.
