Canon 90D vs Pentax K-S1

On this page, we will be comparing the Canon 90D versus Pentax K-S1, both Advanced DSLR cameras by manufacturers Canon and Pentax. There exists a big gap among the image resolutions of the 90D (33MP) and K-S1 (20MP) but both cameras have the same sensor size (APS-C).

The 90D was revealed 5 years later than the K-S1 and that is a fairly big gap as far as camera technology is concerned. Each of these cameras have the same body design (Mid-size SLR).

Before we go right into a thorough comparison, here is a concise introduction of how the 90D grades versus the K-S1 with respect to portability, imaging, features and an overall rating.

Below is a preview of the gallery images for Canon EOS 90D and Pentax K-S1. The full galleries are available at Canon 90D Gallery and Pentax K-S1 Gallery.

If you are planning to carry your camera often, you should consider its weight and dimensions.

Take into consideration, the weight of an Interchangeable Lens Camera will differ based on the lens you have chosen during that time. Below is a front view dimension comparison of the 90D vs the K-S1.

Taking into consideration dimensions and weight, the portability grade of the 90D and K-S1 is 60 and 69 respectively.

Sometimes, it can be tough to see the difference in sensor sizing merely by going through technical specs. The photograph here might provide you a much better sense of the sensor dimensions in the 90D and K-S1.

As you have seen, both the cameras have the same sensor dimensions albeit not the same resolution. You should expect the Canon 90D to provide more detail because of its extra 13MP. Higher resolution will also make it easier to crop photographs a bit more aggressively. The fresher 90D will have a benefit in sensor innovation.
