4 Reasons For
A lot higher megapixel Edit
The Pentax K-S2 has a megapixel of 20.12MP, but the Nikon D90 is only a 12.3MP digital camera (7.82MP 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.

A little higher display resolution (numeric) Edit
The Pentax K-S2 has a display resolution (numeric) of 921,000 pixels, however the Nikon D90 is only a 920,000 pixels display resolution digital camera (1,000 pixels lower).
Lighter Edit
The Pentax K-S2 is a 618g digital camera. That's 2g lighter than the Nikon D90 (618g). Read more

The camera's weight will depend on the type and size of camera. Compact cameras are usually the lightest while digital SLRs will be heavier. Also consider the number and weight of lenses to take when using a SLR.

The lower the camera weight, the easier it will be to carry around and it will also reduce your hand luggage weight when flying.

Available from 5 shops
