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
33% higher megapixel count Edit
The Sony SLT-A99 is a 24.3MPMP digital camera. That's 8MP higher than the Pentax K-5 II (24.3MPMP). 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.

2.8 smaller minimum aperture Edit
The Sony SLT-A99 has a minimum aperture of 2.8, whereas the Pentax K-5 II is a 5.6 minimum aperture digital camera (2.8 larger).
