Olympus 1s vs Pentax K-5 Sensor Comparison

In many cases, it's tough to imagine the difference between sensor sizing purely by reading through a spec sheet. The graphic below will provide you a much better sense of the sensor sizes in the 1s and K-5.

Clearly, the 2 cameras come with different resolutions and different sensor sizing. The 1s featuring a tinier sensor is going to make shooting shallower depth of field more difficult and the Pentax K-5 will give you extra detail due to its extra 4MP. Higher resolution can also make it easier to crop pictures a good deal more aggressively. The fresher 1s should have an advantage with regard to sensor innovation.
