The resolution of the images a digital camera produces is measured in megapixels (MP). One megapixel is equal to 1 million pixels and is a result of the pixel width multiplied by the pixel height of the image. While a higher image resolution generally results in sharper images, only a relatively low megapixel count is required when printing the image at a small size or to display it on a computer screen.

16 Reasons Against
22% lower megapixel count Edit
The Pentax K-S2 has a megapixel count of 20.12MP, however the Pentax K-3 is a 23.35MP digital camera (3.23MP higher), the Pentax K-3 II is a 24.35MP digital camera (4.23MP higher) and the Pentax K-30 is a 16.28MP digital camera (3.84MP lower). Read more

The resolution of the images a digital camera produces is measured in megapixels (MP). One megapixel is equal to 1 million pixels and is a result of the pixel width multiplied by the pixel height of the image. While a higher image resolution generally results in sharper images, only a relatively low megapixel count is required when printing the image at a small size or to display it on a computer screen.

A sensor with more megapixels will be able to capture more detailed photos and the image will appear sharper. Images with more megapixels can also be printed at a larger size.

4.29MP less total megapixel count Edit
The Pentax K-S2 has a total megapixel count of 20.42MP, whereas the Pentax K-3 and the Pentax K-3 II are both 24.71MP digital cameras (4.29MP more) and the Pentax K-30 is a 16.49MP digital camera (3.93MP less).
