Canon 90D vs Pentax K-3

On this page, we will be contrasting the Canon 90D and Pentax K-3, both Advanced DSLR cameras by brands Canon and Pentax. There exists a sizeable gap among the resolutions of the 90D (33MP) and K-3 (24MP) but both cameras provide the same sensor sizes (APS-C).

The 90D was announced 5 years later than the K-3 and that is a fairly large gap as far as camera technology is concerned. Both the cameras have the same body design (Mid-size SLR).

Before we go right into a thorough comparison, here is a quick view of how the 90D grades against the K-3 in the way of portability, imaging, features and an overall grade.

Following is a preview of the gallery images for Canon EOS 90D and Pentax K-3. The whole galleries are viewable at Canon 90D Gallery and Pentax K-3 Gallery.

For those who are looking to lug around your camera regularly, you'll have to factor its weight and proportions.

Do not forget, the weight of an Interchangeable Lens Camera will vary depending on the lens you choose at that moment. Below is a front view dimension comparison of the 90D and the K-3.

Factoring in dimensions and weight, the portability rating of the 90D and K-3 is 60 and 59 respectively.

Sometimes, it's hard to visualise the difference in sensor measurements only by seeing specifications. The photograph below may give you a better sense of the sensor sizing in the 90D and K-3.

Plainly, both cameras have the same sensor dimensions albeit not the same MP. You should expect the Canon 90D to provide extra detail with its extra 9 Megapixels. Higher resolution can also enable you to crop photographs a bit more aggressively. The more recent 90D is going to have an advantage with regard to sensor innovation.
