Weighing 1.23lbs, it’s a relatively lightweight option. However, considering the advancements in camera technology since its release, the K-S1 faces stiff competition in today’s market. Despite its decent score and user-friendly design, the camera’s age may deter potential buyers who are looking for more up-to-date features.

Pentax K-S1 Overview and Optics

The Pentax K-S1 optics score is 68/100. With 20.12 megapixels, a shooting speed of 5.4, and a CMOS sensor, the camera provides decent image quality. The Prime MII processor and DXOMARK sensor score of 78 further contribute to the camera’s performance.

The camera’s sensor size is APS-C, which is common among DSLR cameras. It has a Pentax KAF lens mount, offering compatibility with a wide range of lenses. Additionally, the K-S1 features image stabilization, ensuring sharp images even in challenging situations. The aspect ratio of 3:2 is also standard, providing a familiar format for photographers.

Considering today’s market, the Pentax K-S1 optics are satisfactory for general photography purposes but may not stand out among its competitors. However, the camera’s compatibility with numerous lenses and the inclusion of image stabilization make it a solid choice for those seeking a versatile DSLR.

The higher the number of megapixels, the more detail the cameras sensor can capture.

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.
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.

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.
Minimum ISO (Native)
Refers to the lowest native (or 'base') ISO setting. Lower ISO are less sensitive to light but make a cleaner image.
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.
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.
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.
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.
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.

Pentax K-S1 Video Performance

The Pentax K-S1 has a video score of 43 out of 100. The camera offers Full HD video resolution with maximum dimensions of 1920 x 1080 pixels. Its maximum video frame rate is 30fps, which is standard for most cameras in the market. However, the Pentax K-S1 does not have built-in time-lapse functionality.

Comparing the Pentax K-S1’s video capabilities to other cameras in the market, it falls short in terms of advanced features. Many contemporary cameras offer 4K video resolution, higher frame rates, and built-in time-lapse functionality. The K-S1’s video features are basic and may not satisfy the needs of users who require advanced video capabilities.

The Pentax K-S1 is not the ideal choice for users seeking top-notch video performance. Its video capabilities are limited compared to other cameras available today. The K-S1 is better suited for photographers who prioritize still images over video features.

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.
