The Pentax K20D receives a score of 47/100 for its general specifications. Launched in 2008 with a price of $770, this DSLR camera measures 142 x 101 x 70mm and weighs 1.76 lbs (800g). Compared to today’s market, the K20D’s specifications may seem outdated, especially considering its age and weight. Nevertheless, this camera still holds a respectable place among DSLR enthusiasts who appreciate its sturdy build and reliable performance.

Pentax K20D Overview and Optics

The Pentax K20D optics score is 49 out of 100. This camera features a 14.6-megapixel CMOS sensor, which is an APS-C size. The shooting speed of 3 frames per second is lower than many modern cameras. However, the camera’s Prime processor ensures efficient image processing.

The Pentax K20D has a DXOMARK sensor score of 65, which is respectable but not outstanding in today’s market. The camera uses the Pentax KAF lens mount, offering compatibility with a wide range of lenses. With built-in image stabilization, the K20D reduces the effects of camera shake for sharper images.

The camera’s aspect ratio is 3:2, which is a standard format for photography. Comparing the Pentax K20D optics to current camera models, it provides a decent performance but falls short in some areas, such as shooting speed and sensor score.

The higher the number of megapixels, the more detail the cameras sensor can capture.
14.6 MP
Image Resolution
Image resolution is measured in pixels and megapixels, width by height. The higher the number, the higher its resolution.
4672 x 3104 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.
16 x 23 mm
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.
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.
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/ 4000 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.

Time-Lapse Built In
A built in time-lapse mode will allow continuous shooting throughout a prolonged period of time to be compressed into a sped up video.

Pentax K20D Features and Benefits

The Pentax K20D receives a feature score of 47 out of 100. Its screen size measures 2.7 inches with a resolution of 230,000 dots. The camera does not have a touchscreen, flip screen, GPS, WIFI, or Bluetooth capabilities.

When comparing these features to modern cameras, the K20D seems to fall behind. Many current models offer touchscreens and flip screens for ease of use and improved composition. Additionally, the lack of GPS, WIFI, and Bluetooth limits the camera’s connectivity and sharing options.

The Pentax K20D’s specifications reveal that it might not be the best choice for those seeking advanced features and seamless connectivity. However, for users who prioritize simplicity and are not concerned with the latest technology, the K20D still provides a solid shooting experience.

Built-in Flash
A built-in flash will often be positioned right above the lens. This will automatically pop up when you activate it.
External Flash
External flashes are often connected through a hot shoe at the top of a camera, or a cable at the side of the camera.
GPS features in a camera will include location metadata to each of your photographs.
Weather Sealing
Weather sealing capabilities will give you more confidence when shooting in unfavourable conditions.
Screen Type
Touch Screen
Touchscreen allows you to change camera settings and access menus with a swipe of your finger, instead of using buttons.
Screen Size
Screen Resolution
Screen dots indicate the resolution of the LCD screen by including each sub pixel.
230,000 dots
Flip Screen
A flip screen (or articulating screen) is a second screen which can flip out from the side or top of the camera. This rotating screen allows you more freedom to take photos at different angles.
Live View
Live View feature allows you to see a continuous live video of what is being seen through your lens.
Bluetooth capabilities allow you wireless control of your camera with other external devices.

Pentax K20D Storage and Battery

The Pentax K20D receives a storage and battery score of 27 out of 100. The camera has a single memory card slot, accepting SD, SDHC, and MMC cards. In today’s market, this limitation may be an inconvenience for photographers who prefer multiple card slots for backup or overflow storage.

The battery life of the Pentax K20D allows for 500 shots, powered by a D-LI50 battery. This capacity is decent, but not exceptional compared to current cameras. Additionally, the camera lacks USB charging, which is a feature found in many modern models.

Considering these specifications, the Pentax K20D’s storage and battery performance is adequate but falls short in comparison to newer cameras on the market.
