Canon 6D vs Pentax K-3

Here, we will be evaluating the Canon 6D and Pentax K-3, both Advanced DSLR cameras by brands Canon and Pentax. The image resolution of the 6D (20MP) and the K-3 (24MP) is relatively close but the 6D (Full frame) and K-3 (APS-C) boast different sensor sizing.

Photography Glossary

The 6D was revealed 14 months earlier than the K-3 which makes them a generation away from each other. Both the cameras feature the same body design (Mid-size SLR).

Before diving right into a detailed comparison, here is a simple highlight of how the 6D scores against the K-3 in the way of portability, imaging, features and an overall score.

Below is a preview of the gallery photos for Canon EOS 6D & Pentax K-3. The full galleries are viewable at Canon 6D Gallery & Pentax K-3 Gallery.

Do not forget, the weight of an ILC will vary dependant on the lens you are working with at that moment. The following is a front view measurement comparison of the 6D and the K-3.

Considering size and weight, the portability score of the 6D and K-3 is 59 and 59 respectively.

In many cases, it is tough to picture the difference in sensor sizes purely by viewing technical specs. The picture underneath will help provide you a greater sense of the sensor dimensions in the 6D and K-3.

As you can tell, both cameras feature different megapixels and different sensor sizes. The 6D with its bigger sensor is going to make achieving shallower DOF simpler and the Pentax K-3 will render greater detail because of its extra 4 Megapixels. Higher resolution will also help you crop photographs way more aggressively. The more aged 6D will be disadvantaged in sensor innovation.
