Canon EOS Rebel T5 is equipped with DIGIC 4 processor and can take pictures up to 5184 x 3456 resolution. It can also take pictures with lower resolution like 3456 x 2304, 2592 x 1728 with 3:2 aspect ratios. Pentax K-S1 is equipped with PRIME MII processor and can take pictures up to 5472 x 3648 resolution. It can also take pictures with lower resolution like 4224 x 2816, 3456 x 2304, 3072 x 2448, 1920 x 1080 with 3:2 aspect ratios.

Lens Mount

Canon EOS Rebel T5 has Canon EF/EF-S lens mount and Pentax K-S1 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 T5 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-S1 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 K-S1

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on Pentax K-S1. 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-S1

Pentax K-S1 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.

USB Inputs and HDMI Outputs

Both models have USB 2.0 (480 Mbit/sec) inputs for data transfer. Canon EOS Rebel T5 has a Mini HDMI and Pentax K-S1 has a Micro HDMI connector for video signal output.
