Image Resolution Image resolution is measured in pixels and megapixels, width by height. The higher the number, the higher its resolution. | 5472 x 3648 px |
Sensor Type The camera sensor captures light and records the image. Sensors vary in physical size, the number of pixels, and quality. | CMOS |
Sensor Size The sensor size contributes to the overall quality as well as the dynamic and tonal range a camera can capture. As a rule of thumb, the more surface there is to read the light, the more information it will capture. | 15.6 x 23.5 mm |
Sensor Format Refers to the most commonly used sensor sizes. |  APS-C |
Frame Rate The number of sequential frames per second the camera can write to the memory card when shooting in burst or continuous mode. | 5.4 fps |
Lens Mount The lens mount will tell you what type of lens range you can fit onto the camera body. Often the same camera company will have different lens ranges for different cameras. | Pentax KAF |
Image Processor The image processor in the camera converts the information collected on the sensor for digital storage on the memory card. | Prime MII |
Aspect Ratio The aspect ratio refers to the proportional difference between width and height. The most popular aspect ratios are 3:2 and 4:3. |  3:2 |
Minimum ISO (Native) Refers to the lowest native (or 'base') ISO setting. Lower ISO are less sensitive to light but make a cleaner image. | 100 |
Maximum ISO (Native) Refers to the highest native (or 'base') ISO setting. Higher ISO is necessary for low-light situations or night photography, but higher ISOs often introduce grain or noise. | 51,200 |
Minimum ISO (Expanded) Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary. | 100 |
Maximum ISO (Expanded) Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary. | 51200 |
Minimum Shutter Speed The minimum shutter speed will tell you the longest exposure your camera can take without using an external accessory. | 30 s |
Maximum Shutter Speed The maximum shutter speed tells you the length inside 1 second the camera will capture. These can sometimes be extended with accessories such as extra external batteries. | 1/ 6000 s |
Autofocus Points Autofocus points show where the camera is focusing graphically as squares or brackets in Live View or on an electronic viewfinder. These points are also used for light meter readings. | 11 |
In-body Stabilization In-body Stabilization means the camera has a certain technology embedded that counteracts camera shake. |   |
Viewfinder Type The viewfinder type is either electronic or optical. Electronic viewfinders will have a small screen in the viewfinder. Optical viewfinders will use prisms and mirrors to look through the lens. | Optical (pentaprism) |

Pentax K-S1 Features and Benefits
The Pentax K-S1 features a score of 41/100, which is a modest rating for camera features. The camera comes with a 3-inch screen, offering a resolution of 921,000 dots. However, it lacks some modern functionalities, such as a touchscreen, flip screen, GPS, WiFi, and Bluetooth connectivity.
In the current market, these specifications place the Pentax K-S1 at a disadvantage compared to competitors that offer more advanced features. The absence of a touchscreen and flip screen limits the camera’s flexibility and ease of use, while the lack of GPS, WiFi, and Bluetooth connectivity restricts the user’s ability to transfer and share images efficiently.
Considering all factors, the Pentax K-S1 falls short in providing the latest features found in many contemporary cameras. Its limited specifications may not satisfy the needs of users seeking a more advanced and connected photography experience.
