Here is a sensor size comparison chart where you can see how Pentax K-S2's APS-C sensor compares with other types of sensors:
| Sensor | Dimensions | Area | Aspect Ratio | Crop Factor | |
|---|---|---|---|---|---|
 | Medium Format | 44 x 33 mm | 1452 mm2 | 4:3 | 0.79x |
 | Full Frame | 36 x 24 mm | 864 mm2 | 3:2 | 1x |
 | APS-H | 27 x 18 mm | 486 mm2 | 3:2 | 1.3x |
 | APS-C | 23.5 x 15.6 mm | 366.6 mm2 | 3:2 | 1.5x |
 0.webp) | APS-C (Canon) | 22.3 x 14.9 mm | 332.3 mm2 | 3:2 | 1.6x |

Camera is equipped with PRIME MII processor and can take pictures up to 5472 x 3648 resolution. It can also take pictures with lower resolutions like 4224 x 2816, 3072 x 2048, 1920 x 1280 with 3:2 aspect ratios.
Pentax K-S2 has Pentax KAF2 lens mount. Due to APS-C sensor its crop factor (also called lens multiplier) is 1.5x. This means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 1.5.
There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor. 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.
The camera 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.
Camera has a built-in Wi-Fi 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.

Pentax K-S2 has Near Field Communication (NFC) technology which simplifies the process of pairing it with other NFC-enabled devices like smartphones or tablets. It allows to quickly transfer photos and videos or remotely control the camera from compatible device. NFC can also be used for authentication and security purposes. It can verify your identity before accessing certain features or transferring sensitive data. It can be used with NFC-enabled accessories as well, such as lenses, flashes and GPS devices.
Pentax K-S2 has a USB 2.0 (480 Mbit/sec) input for data transfer. There is a Micro HDMI connector for video signal output.
