Canon 7D vs Pentax K-3

Let's look more in depth at the Canon 7D vs Pentax K-3, both Advanced DSLR cameras by rivals Canon and Pentax. There is a sizeable difference among the image resolutions of the 7D (18MP) and K-3 (24MP) but both cameras have the same sensor sizes (APS-C).

The 7D was brought out 5 years prior to the K-3 and that is a fairly large gap as far as camera tech is concerned. Both of the cameras have the same body design (Mid-size SLR).

Before getting straight to a step-by-step comparison, here is a quick summary of how the 7D scores against the K-3 with regards to portability, imaging, features and an overall grade.

The following is a preview of the gallery images for Canon EOS 7D and Pentax K-3. The entire galleries are viewable at Canon 7D Gallery and Pentax K-3 Gallery.

For anybody who is aiming to lug around your camera regularly, you will want to take into account its weight and proportions. The Canon 7D has outer measurements of 148mm x 111mm x 74mm (5.8" x 4.4" x 2.9") and a weight of 860 grams (1.90 lbs) while the Pentax K-3 has measurements of 131mm x 100mm x 77mm (5.2" x 3.9" x 3.0") along with a weight of 800 grams (1.76 lbs).

Often, it is very tough to see the contrast in sensor measurements purely by looking through a spec sheet. The visual underneath might provide you a better sense of the sensor sizing in the 7D and K-3.

Clearly, the 2 cameras have the same sensor dimensions albeit not the same MP. You should expect the Pentax K-3 to render extra detail having its extra 6MP. Higher resolution will enable you to crop shots a bit more aggressively. The older 7D will be behind when it comes to sensor technology.
