Canon 1D vs Pentax 645D Sensor Comparison

Normally, it's tough to visualise the gap in sensor sizes just by checking out specifications. The picture here might give you a more clear sense of the sensor sizes in the 1D and 645D.

To sum up, both the cameras feature different megapixels and different sensor sizes. The 1D having a smaller sensor will make getting bokeh more challenging and the Pentax 645D will show more detail with its extra 36 Megapixels. Greater resolution will also make it easier to crop pics way more aggressively. The more aged 1D will be disadvantaged with regard to sensor tech.
