In many cases, it's hard to picture the gap in sensor measurements merely by going through a spec sheet. The visual here may give you a stronger sense of the sensor dimensions in the K-r and A33.

Higher resolution can also enable you to crop shots a bit more aggressively. The fresher K-r should have an advantage when it comes to sensor tech.
