Canon 1D MII vs Pentax 645D Sensor Comparison

Normally, it is hard to see the gap between sensor measurements purely by reviewing specifications. The graphic underneath will offer you a far better sense of the sensor sizing in the 1D MII and 645D.

To sum up, both cameras have different resolutions and different sensor measurements. The 1D MII having a tinier sensor will make shooting shallower depth of field harder and the Pentax 645D will offer more detail having an extra 32MP. Greater resolution will also allow you to crop photos a bit more aggressively. The older 1D MII is going to be behind with regard to sensor tech.
