Canon 7D vs Pentax K-3 III

Let's look closer at the Canon 7D versus Pentax K-3 III, both Advanced DSLR cameras by rivals Canon and Pentax. There exists a sizeable gap among the image resolutions of the 7D (18MP) and K-3 III (26MP) but both cameras offer the same sensor sizing (APS-C).

The 7D was revealed 12 years earlier than the K-3 III which is a fairly large gap as far as camera technology is concerned. Both of the cameras have the same body design (Mid-size SLR).

Before getting into a full comparison, here is a short summary of how the 7D matches up versus the K-3 III with regard to portability, imaging, features and an overall score.

Here is a preview of the gallery images for Canon EOS 7D and Pentax K-3 Mark III. The full galleries are provided at Canon 7D Gallery and Pentax K-3 III Gallery.

For anybody who is looking to carry around your camera regularly, you have to take into account its weight and size. The Canon 7D has external dimensions of 148mm x 111mm x 74mm (5.8" x 4.4" x 2.9") accompanied by a weight of 860 grams (1.90 lbs) whilst the Pentax K-3 III has specifications of 135mm x 104mm x 74mm (5.3" x 4.1" x 2.9") having a weight of 820 grams (1.81 lbs).

Take into consideration, the weight of an Interchangeable Lens Camera will vary based on the lens you have chosen at the time. Here is a front view sizing comparison of the 7D versus the K-3 III.

Taking into account dimensions and weight, the portability grade of the 7D and K-3 III is 56 and 58 respectively.

Normally, it's tough to envision the difference in sensor sizes merely by seeing a spec sheet. The image below may give you a far better sense of the sensor sizes in the 7D and K-3 III.

As you can see, each of the cameras provide the same sensor dimensions albeit not the same MP. You should expect the Pentax K-3 III to provide more detail because of its extra 8MP. Higher resolution will help you crop pictures more aggressively. The more aged 7D will be disadvantaged when it comes to sensor technology.
