Image Resolution
Image resolution is measured in pixels and megapixels, width by height. The higher the number, the higher its resolution.
6016 x 4000 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.

Sensor Format
Refers to the most commonly used sensor sizes.
Frame Rate
The number of sequential frames per second the camera can write to the memory card when shooting in burst or continuous mode.
8.3 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 III
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/ 8000 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-3 Video Performance

The Pentax K-3 has a video score of 70/100. The camera offers Full HD video resolution with maximum dimensions of 1920 x 1080 pixels. With a maximum video frame rate of 60fps, the K-3 provides smooth and clear video quality.

In today’s market, the Pentax K-3’s video capabilities are competitive but not exceptional. Many cameras now offer 4K video resolution, surpassing the K-3’s Full HD offering. However, the 60fps frame rate and time-lapse functionality remain valuable features for users looking to capture high-quality video content.

The Pentax K-3’s video performance is solid, but it is not the top choice for those prioritizing video capabilities. The camera excels in other areas, but potential buyers should consider the K-3’s video specifications and compare them to other options on the market to make an informed decision.

In the current market, these specifications may not be competitive, as most modern cameras come equipped with touchscreens, flip screens, and wireless connectivity options. The absence of GPS, WiFi, and Bluetooth make it challenging for users to transfer images and geotag their photos without additional accessories.

The Pentax K-3’s features may not appeal to photographers seeking advanced technology and convenience in their cameras. However, it still serves as a reliable option for those who prioritize other aspects, such as image quality and performance, over cutting-edge features.
