0.99s shorter flash sync-speed Edit

Three hundred and seventy more shots per battery charge Edit

11 Reasons For
A lot higher megapixel count Edit
The Pentax K-S2 has a megapixel count 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 lot more total megapixel count Edit
The Pentax K-S2 has a total megapixel count of 20.42MP, however the Nikon D90 is only a 12.9MP digital camera (7.52MP less).
Significantly higher maximum ISO speed Edit
The Pentax K-S2 has a maximum ISO speed of 51,200, whereas the Nikon D90 is only a 6,400 maximum ISO speed digital camera (44,800 lower).

0.01x higher lens magnification ratio Edit
The Pentax K-S2 has a lens magnification ratio of 0.95x, whereas the Nikon D90 is only a 0.94x lens magnification ratio digital camera (0.01x lower). Read more

The lens magnification ratio is the ratio between the true size of the object being photographed and the size of the object when projected on to the camera's sensor.

A higher lens magnification ratio is important for macro photography as it allows you to focus on very small object very close to the lens.

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.
