Canon 6D vs Pentax K20D

Lets look more closely at the Canon 6D vs Pentax K20D, both Advanced DSLR digital cameras by rivals Canon and Pentax. There is a significant difference between the image resolutions of the 6D (20MP) and K20D (15MP) and the 6D (Full frame) and K20D (APS-C) boast totally different sensor sizing.

The 6D was revealed 4 years later than the K20D and that is quite a sizable gap as far as tech is concerned. The two cameras have the same body design (Mid-size SLR).

Before we go into a more detailed comparison, here is a quick introduction of how the 6D scores against the K20D for portability, imaging, features and an overall rating.

Below is a preview of the gallery images for Canon EOS 6D and Pentax K20D. The full galleries are viewable at Canon 6D Gallery and Pentax K20D Gallery.

If you're going to carry your camera frequently, you're going to have to think about its weight and dimensions. The Canon 6D provides external dimensions of 145mm x 111mm x 71mm (5.7" x 4.4" x 2.8") with a weight of 770 grams (1.70 lbs) whilst the Pentax K20D has dimensions of 142mm x 101mm x 70mm (5.6" x 4.0" x 2.8") having a weight of 800 grams (1.76 lbs).

Remember that, the weight of an Interchangeable Lens Camera will change based on the lens you have at the time. Underneath is a front view measurement comparison of the 6D against the K20D.

Using size and weight, the portability rating of the 6D and K20D is 59 and 59 respectively.

Often, it is difficult to visualise the gap between sensor sizing simply by reviewing technical specs. The visual here might give you a much better sense of the sensor dimensions in the 6D and K20D.

As you have seen, the two cameras have different resolutions and different sensor sizing. The 6D with its bigger sensor will make shooting shallow DOF easier and the Canon 6D will offer you more detail because of its extra 5MP. Higher resolution will help you crop shots a bit more aggressively. The more recent 6D is going to have an advantage when it comes to sensor technology.
