Pentax K-5 compared to K-7 and K-r
The table below shows the specification differences between the K-5's predecessor, the K-7, and the recently released K-r. Apart from the new sensor, the differences between the K-5 and the older K-7 are quite subtle. It is clear that Pentax has opted for selective improvements rather than a complete overhaul.
