Pentax 645D vs Pentax KP

Its time to look a bit more in depth at the Pentax 645D and Pentax KP, one is a Pro DSLR and the latter is a Advanced DSLR and they are both produced by Pentax. There exists a big gap among the resolutions of the 645D (40MP) and KP (24MP) and the 645D (Medium format) and KP (APS-C) offer totally different sensor sizing.

The 645D was released 7 years prior to the KP which is a fairly big gap as far as camera technology is concerned. Both cameras feature different body design with the Pentax 645D being a Large SLR camera and the Pentax KP being a Mid-size SLR camera.

Before delving into a more detailed comparison, here is a concise summary of how the 645D grades against the KP in relation to portability, imaging, features and an overall score.

Normally, it can be hard to visualise the difference in sensor sizes purely by seeing specs. The pic below should offer you a clearer sense of the sensor sizing in the 645D and KP.

All in all, both of those cameras come with different resolutions and different sensor sizes. The 645D because of its bigger sensor will make achieving shallow DOF less difficult and the Pentax 645D will produce greater detail as a result of its extra 16MP. Higher resolution will also enable you to crop photographs a good deal more aggressively. The more aged 645D will be disadvantaged when it comes to sensor innovation.
