Reasons For

5 Reasons For
25,600 higher ISO sensitivity (max) Edit
The Pentax K-5 II is a 51,200 maximum ISO speed digital camera, whereas the Sony SLT-A99 is only a 25,600 maximum ISO speed digital camera (25,600 lower).
25% smaller ISO sensitivity (min) Edit
The Pentax K-5 II has an ISO sensitivity (min) of 80, however the Sony SLT-A99 is a 100 minimum ISO speed digital camera (20 bigger).
0.21x higher magnification Edit
The Pentax K-5 II is a 0.92x lens magnification ratio digital camera, whereas the Sony SLT-A99 is only a 0.71x lens magnification ratio digital camera (0.21x 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.

8% lighter Edit
The Pentax K-5 II is a 680g digital camera. That's 53g lighter than the Sony SLT-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.

Two hundred and fourty more battery life (CIPA standard)s Edit
The Pentax K-5 II takes 740.00 battery life (CIPA standard)s, however the Sony SLT-A99 only takes 500.00 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.

3 Reasons For
33% higher megapixel Edit
The Sony SLT-A99 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.

2.8 smaller minimum aperture number Edit
The Sony SLT-A99 is a 2.8 minimum aperture digital camera, whereas the Pentax K-5 II is a 5.6 minimum aperture digital camera (2.8 larger).
26% higher display resolution (numeric) Edit
The Sony SLT-A99 has a display resolution (numeric) of 1,228,800 pixels. That's 307,800 pixels higher than the Pentax K-5 II (1,228,800 pixels).
