To sum up, both of those cameras feature different resolutions and different sensor measurements. The 1Ds with its larger sensor will make achieving shallow depth of field simpler and the Pentax K-S1 will deliver more detail using its extra 9MP. Greater resolution will also help you crop pics way more aggressively. The older 1Ds is going to be behind in sensor innovation.
