Reasons For

4 Reasons For
Image stabilizer Edit
The Nikon D90 has an image stabilizer, but the Pentax K-S2 does not have an image stabilizer. Read more

Camera shake is a major cause of blurred images, especially with handheld photography or in low light situations where a slow shutter speed is required. Image stabiliser technology detects and corrects slight camera shakes.

Cameras with image stabiliser technology enable steady shooting at lower aperture, making them ideal for situations where the use of flash is not permitted or desired.

17.00 flash guide numbers Edit
The Nikon D90 is a 17.00 flash guide number digital camera, whereas the Pentax K-S2 only has 12.00 flash guide numbers.
0.99s shorter flash sync-speed Edit
The Nikon D90 is a 0.01s flash sync-speed digital camera. That's 0.99s shorter than the Pentax K-S2 (1s).
Three hundred and seventy more battery life (CIPA standard)s Edit
The Nikon D90 is a digital camera that takes 850.00 battery life (CIPA standard)s, whereas the Pentax K-S2 only takes 480.00 battery life (CIPA standard)s. Read more

The number of shots per battery charge is the number of photos that the camera will typically take on a single charge of the battery.

More shots per battery charge means you will have to recharge the battery less frequently and reduces the need to carry a second back up battery.

7 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 lot more total megapixels Edit
The Pentax K-S2 has a total megapixels of 20.42MP, however the Nikon D90 is only a 12.9MP digital camera (7.52MP less).
Significantly higher ISO sensitivity (max) Edit
The Pentax K-S2 is a 51,200 maximum ISO speed digital camera, whereas the Nikon D90 is only a 3,200 maximum ISO speed digital camera (48,000 lower).
Vastly higher motion JPEG frame rate Edit
The Pentax K-S2 has a motion JPEG frame rate of 50fps, however the Nikon D90 is only a 24fps JPEG frame rate digital camera (26fps lower).
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).
0.01x higher magnification Edit
The Pentax K-S2 is a 0.95x lens magnification ratio digital camera, 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.
