Canon 7D vs Pentax K-S1

Let's look a bit more closely at the Canon 7D versus Pentax K-S1, both Advanced DSLR digital cameras by competitors Canon and Pentax. The resolution of the 7D (18MP) and the K-S1 (20MP) is relatively similar and both cameras posses the same sensor dimensions (APS-C).

The 7D was revealed 5 years prior to the K-S1 and that is quite a big gap as far as tech is concerned. The two cameras have the same body design (Mid-size SLR).

Before getting straight to a step-by-step comparison, here is a concise introduction of how the 7D matches up versus the K-S1 with regards to portability, imaging, features and an overall rating.

Here is a preview of the gallery photos for Canon EOS 7D and Pentax K-S1. The full galleries are viewable at Canon 7D Gallery and Pentax K-S1 Gallery.

For anyone who is looking to carry your camera frequently, you should factor in its weight and measurements. The Canon 7D offers 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) while the Pentax K-S1 has proportions of 121mm x 93mm x 70mm (4.8" x 3.7" x 2.8") and a weight of 558 grams (1.23 lbs).

Look at the Canon 7D versus Pentax K-S1 in the new Camera with Lens Size Comparison Tool.

Bear in mind, the weight of an Interchangeable Lens Camera will differ based on the lens you use during that time. Underneath is a front view over all size comparison of the 7D against the K-S1.

Looking at size and weight, the portability score of the 7D and K-S1 is 56 and 69 respectively.

Generally, it is difficult to imagine the gap between sensor sizing purely by going over specs. The photograph underneath might give you a more clear sense of the sensor dimensions in the 7D and K-S1.

All in all, both of those cameras have the same sensor dimensions albeit different resolution. You should count on the Pentax K-S1 to deliver extra detail because of its extra 2MP. Higher resolution can also allow you to crop shots a bit more aggressively. The older 7D is going to be behind in sensor innovation.
