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

The resolution of the images a digital camera produces is measured in megapixels (MP).

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.

The Sony Alpha A99 is a 24.7MPMP digital camera. That's 11.8MP more than the Nikon D90 (24.7MPMP).
