Canon 70D vs Pentax K-3 III

Let's examine more closely at the Canon 70D versus Pentax K-3 III, both Advanced DSLR digital cameras by manufacturers Canon and Pentax. There is a huge difference between the resolutions of the 70D (20MP) and K-3 III (26MP) but they enjoy the exact same sensor dimensions (APS-C).

The 70D was introduced 8 years prior to the K-3 III which is quite a significant gap as far as tech is concerned. Both cameras come with the identical body type (Mid-size SLR).

Before diving in to a in-depth comparison, below is a simple summation of how the 70D grades against the K-3 III with regards to portability, imaging, features and an overall mark.

Following is a sample of the gallery pics for Canon EOS 70D and Pentax K-3 Mark III. The whole galleries are provided at Canon 70D Gallery and Pentax K-3 III Gallery.

When you are planning to travel with your camera often, you will need to take into account its weight and size. The Canon 70D has got outside dimensions of 139mm x 104mm x 79mm (5.5" x 4.1" x 3.1") along with a weight of 755 grams (1.66 lbs) while 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).

Always remember, the weight of an Interchangeable Lens Camera will differ depending on the lens you have attached at that time. Underneath is the front view sizing comparison of the 70D compared to the K-3 III.

Taking into account size and weight, the portability grade of the 70D and K-3 III is 59 and 58 respectively.

Generally, it's difficult to picture the difference between sensor dimensions just by looking at specs. The picture underneath might give you a much better sense of the sensor sizes in the 70D and K-3 III.

All in all, both of these cameras posses the exact same sensor measurements but different MP. You should expect to see the Pentax K-3 III to resolve greater detail using its extra 6 Megapixels. Greater resolution can also enable you to crop images somewhat more aggressively. The more aged 70D is going to be behind in sensor innovation.
