Typically, it is difficult to visualize the difference between sensor sizes just by looking at a spec sheet. The image here may provide you a much better sense of the sensor sizes in the K-x and A58.

Clearly, both cameras come with the identical sensor size albeit different megapixels. You should count on the Sony A58 to give you extra detail with its extra 8 Megapixels. Higher resolution will also help you crop photographs a good deal more aggressively. The more aged K-x is going to be behind in sensor innovation.
