Plainly, both of the cameras posses different megapixel count and different sensor measurements. The K-5 because of its smaller sensor will make shooting shallow depth of field tougher and the Sony A900 will provide greater detail as a result of its extra 9MP. Higher resolution will help you crop shots somewhat more aggressively. The newer K-5 is going to have an edge when it comes to sensor innovation.
