Pentax 645D vs Sony H400

Let's examine more in depth at the Pentax 645D and Sony H400, one being a Pro DSLR and the latter is a Small Sensor Superzoom by rivals Pentax and Sony. There exists a significant gap among the resolutions of the 645D (40MP) and H400 (20MP) and the 645D (Medium format) and H400 (1/2.3") enjoy different sensor sizing.

The 645D was introduced 4 years earlier than the H400 and that is a fairly sizable gap as far as camera technology is concerned. Both cameras come with different body type with the Pentax 645D being a Large SLR camera and the Sony H400 being a SLR-like (bridge) camera.

Before delving through a complete comparison, below is a simple view of how the 645D scores against the H400 when it comes to portability, imaging, features and an overall rating.

Here is a preview of the gallery images for Pentax 645D and Sony Cyber-shot DSC-H400. The whole galleries are available at Pentax 645D Gallery and Sony H400 Gallery.

For anyone who is aiming to carry your camera frequently, you have to think about its weight and measurements.

Do not forget, the weight of an Interchangeable Lens Camera will vary based on the lens you are working with at the time. Underneath is the front view physical size comparison of the 645D against the H400.

Considering dimensions and weight, the portability rating of the 645D and H400 is 50 and 62 respectively.

Typically, it can be hard to picture the difference in sensor sizing only by going through specs. The visual here might offer you a better sense of the sensor measurements in the 645D and H400.

All in all, the 2 cameras posses different megapixel count and different sensor sizing. The 645D with its bigger sensor is going to make getting shallower depth of field less difficult and the Pentax 645D will show greater detail using its extra 20 Megapixels. Higher resolution can also let you crop shots somewhat more aggressively. The older 645D will be behind in sensor technology.
