Canon 10D vs Pentax K-3

Let's look much closer at the Canon 10D and Pentax K-3, both Advanced DSLR cameras by manufacturers Canon and Pentax. There exists a considerable gap among the resolutions of the 10D (6MP) and K-3 (24MP) but they come with the same exact sensor dimensions (APS-C).

The 10D was unveiled 12 years before the K-3 which is a fairly large difference as far as camera technology is concerned. Each of these cameras offer the identical body type (Mid-size SLR).

Before going straight into a in-depth comparison, below is a concise summation of how the 10D matches up versus the K-3 for portability, imaging, features and an overall mark.

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

If you're looking to travel with your camera, you will have to think about its weight and measurements. The Canon 10D provides outer dimensions of 150mm x 107mm x 75mm (5.9" x 4.2" x 3.0") having a weight of 875 grams (1.93 lbs) while the Pentax K-3 has proportions of 131mm x 100mm x 77mm (5.2" x 3.9" x 3.0") along with a weight of 800 grams (1.76 lbs).

Bear in mind, the weight of an ILC will differ depending on the lens you have attached at the time. Following is the front view physical size comparison of the 10D against the K-3.

Taking into account dimensions and weight, the portability grade of the 10D and K-3 is 56 and 59 respectively.

Quite often, it's difficult to visualize the contrast in sensor dimensions simply by looking through technical specs. The image below might provide you a more clear sense of the sensor dimensions in the 10D and K-3.

As you have seen, each of these cameras enjoy the same exact sensor sizing but different megapixels. You can expect to see the Pentax K-3 to result in greater detail having an extra 18 Megapixels. Greater resolution can also make it easier to crop photos far more aggressively. The more aged 10D will be behind in sensor innovation.
