Canon 10D vs Pentax K-3 III

Here is a detailed review of the Canon 10D and Pentax K-3 III, both Advanced DSLR digital cameras by rivals Canon and Pentax. There exists a large gap between the image resolutions of the 10D (6MP) and K-3 III (26MP) but both cameras offer the identical sensor dimensions (APS-C).

The 10D was revealed 19 years before the K-3 III and that is quite a serious difference as far as technology is concerned. Each of the cameras feature the same body design (Mid-size SLR).

Before going right into a detailed comparison, here is a quick view of how the 10D matches up vs the K-3 III when considering portability, imaging, features and an overall rating.

The following is a sample of the gallery pics for Canon EOS 10D & Pentax K-3 Mark III. The full galleries are provided at Canon 10D Gallery & Pentax K-3 III Gallery.

For those who are going to carry your camera often, you're going to have to think about its weight and measurements.

Don't forget, the weight of an ILC will differ depending on the lens you are working with at that moment. Following is a front view physical size comparison of the 10D compared to the K-3 III.

Using dimensions and weight, the portability score of the 10D and K-3 III is 56 and 58 respectively.

More often than not, it is very difficult to picture the difference between sensor sizing only by reading through a spec sheet. The photograph below might give you a stronger sense of the sensor measurements in the 10D and K-3 III.

Clearly, both cameras feature the identical sensor size but different resolution. You can expect to see the Pentax K-3 III to give more detail because of its extra 20 Megapixels. Greater resolution will enable you to crop pics way more aggressively. The older 10D is going to be disadvantaged when it comes to sensor technology.
