Pentax 645D vs Pentax RZ10

Below is a in depth assessment of the Pentax 645D and Pentax RZ10, one being a Pro DSLR and the latter is a Small Sensor Compact and both are built by Pentax. There exists a big gap between the image resolutions of the 645D (40MP) and RZ10 (14MP) and the 645D (Medium format) and RZ10 (1/2.3") enjoy totally different sensor size.

The 645D was introduced 16 months prior to the RZ10 which makes the cameras a generation apart from one another. The two cameras offer different body type with the Pentax 645D being a Large SLR camera and the Pentax RZ10 being a Compact camera.

Before getting in to a thorough comparison, below is a brief summation of how the 645D scores versus the RZ10 when it comes to portability, imaging, features and an overall grade.

The following is a preview of the gallery photos for Pentax 645D and Pentax Optio RZ10. The whole galleries are provided at Pentax 645D Gallery and Pentax RZ10 Gallery.

For those who are looking to lug around your camera often, you will need to factor in its weight and volume.

Do not forget, the weight of an Interchangeable Lens Camera will vary based on the lens you have at that moment. Underneath is the front view dimension comparison of the 645D versus the RZ10.

Using dimensions and weight, the portability grade of the 645D and RZ10 is 50 and 92 respectively.

Normally, it is tough to envision the gap between sensor measurements just by going over specifications. The visual below should provide you a more clear sense of the sensor sizes in the 645D and RZ10.

Plainly, the two cameras enjoy different resolutions and different sensor measurements. The 645D with its bigger sensor will make shooting shallower DOF easier and the Pentax 645D will offer you extra detail using its extra 26MP. Higher resolution will allow you to crop photographs far more aggressively. The older 645D is going to be disadvantaged in sensor technology.
