Pentax 645D vs Sony H20

Let's look more closely at the Pentax 645D vs Sony H20, one is a Pro DSLR and the other is a Small Sensor Compact by rivals Pentax and Sony. There exists a significant gap between the image resolutions of the 645D (40MP) and H20 (10MP) and the 645D (Medium format) and H20 (1/2.3") provide different sensor dimensions.

The 645D was announced 10 months after the H20 which means that they are of a similar generation. Both the cameras feature different body design with the Pentax 645D being a Large SLR camera and the Sony H20 being a Compact camera.

Before diving straight to a step-by-step comparison, here is a short summation of how the 645D grades versus the H20 with regard to portability, imaging, features and an overall mark.

Following is a sample of the gallery pictures for Pentax 645D and Sony Cyber-shot DSC-H20. The whole galleries are provided at Pentax 645D Gallery and Sony H20 Gallery.

In case you're planning to travel with your camera often, you're going to have to take into account its weight and measurements. The Pentax 645D enjoys outer measurements of 156mm x 117mm x 119mm (6.1" x 4.6" x 4.7") along with a weight of 1480 grams (3.26 lbs) whilst the Sony H20 has proportions of 107mm x 69mm x 47mm (4.2" x 2.7" x 1.9") with a weight of 250 grams (0.55 lbs).

Quite often, its difficult to imagine the contrast between sensor dimensions merely by reading through a spec sheet. The picture underneath will help offer you a far better sense of the sensor measurements in the 645D and H20.

Clearly, each of the cameras come with different resolutions and different sensor dimensions. The 645D using its larger sensor is going to make shooting shallow depth of field less difficult and the Pentax 645D will give more detail with its extra 30MP. Greater resolution will allow you to crop pics a good deal more aggressively. The more recent 645D should have an edge in sensor technology.
