4 Reasons For
33% higher megapixel count Edit
The Sony Alpha SLT-A77 is a 24.3MP digital camera. That's 8MP higher than the Pentax K-5 II (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.

1% higher display resolution Edit
The Sony Alpha SLT-A77 is a 921,600 pixels display resolution digital camera. That's 600 pixels higher than the Pentax K-5 II (921,600 pixels).
A bit lighter Edit
The Sony Alpha SLT-A77 has a weight of 653g, however the Pentax K-5 II is a 680g digital camera (27g heavier). 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.
