Canon 5D vs Pentax K20D

Lets examine more in depth at the Canon 5D versus Pentax K20D, both Advanced DSLR cameras by manufacturers Canon and Pentax. The sensor resolution of the 5D (13MP) and the K20D (15MP) is fairly comparable but the 5D (Full frame) and K20D (APS-C) use totally different sensor size.

The 5D was manufactured 3 years prior to the K20D and that is a fairly significant difference as far as camera tech is concerned. The two cameras come with the identical body type (Mid-size SLR).

Before we go through a comprehensive comparison, below is a concise summation of how the 5D grades vs the K20D when it comes to portability, imaging, features and an overall grade.

For anyone who is planning to lug around your camera often, you'll need to think about its weight and measurements. The Canon 5D enjoys external dimensions of 152mm x 113mm x 75mm (6.0" x 4.4" x 3.0") accompanied by a weight of 895 grams (1.97 lbs) whilst the Pentax K20D has proportions of 142mm x 101mm x 70mm (5.6" x 4.0" x 2.8") accompanied by a weight of 800 grams (1.76 lbs).

Don't forget, the weight of an ILC will vary depending on the lens you choose at that moment. Here is the front view dimensions comparison of the 5D and the K20D.

Looking at size and weight, the portability rating of the 5D and K20D is 55 and 59 respectively.

In many cases, it's hard to visualise the difference in sensor measurements purely by seeing specs. The graphic underneath should offer you a far better sense of the sensor dimensions in the 5D and K20D.

All in all, both of the cameras have got different resolutions and different sensor measurements. The 5D featuring a larger sensor will make getting shallower DOF easier and the Pentax K20D will produce more detail due to its extra 2MP. Greater resolution can also enable you to crop photos much more aggressively. The older 5D will be disadvantaged when it comes to sensor tech.
