Reasons For

3 Reasons For
Longer maximum focal length (35mm film equiv) Edit

9mm shorter minimum focal length (35mm film equiv) Edit
The Nikon D90 has a minimum focal length (35mm film equiv) of 27mm, however the Sony Alpha A99 is a 36mm minimum focal length digital camera (9mm longer).
Lighter Edit
The Nikon D90 is a 620g digital camera. That's 113g lighter than the Sony Alpha A99 (733g). 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.

3 Reasons For
Higher megapixel Edit
The Sony Alpha A99 is a 24.3MP digital camera. That's 12MP higher than the Nikon D90 (24.3MP). 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.

Smaller maximum aperture number Edit
The Sony Alpha A99 has a maximum aperture number of 22. That's 16.4 smaller than the Nikon D90 (22).
Higher display resolution (numeric) Edit
The Sony Alpha A99 is a 1,228,800 pixels display resolution digital camera. That's 308,800 pixels higher than the Nikon D90 (1,228,800 pixels).
