Canon 400D vs Pentax K-x

In this article, we will be reviewing the Canon 400D and Pentax K-x, both Entry-Level DSLR cameras by competitors Canon and Pentax. The image resolution of the 400D (10MP) and the K-x (12MP) is relatively close and they feature the same exact sensor dimensions (APS-C).

The 400D was manufactured 4 years earlier than the K-x and that is a fairly serious difference as far as camera tech is concerned. Both the cameras offer the identical body type (Compact SLR).

Before diving straight into a in depth comparison, below is a simple introduction of how the 400D grades vs the K-x in regards to portability, imaging, features and an overall rating.

Following is a preview of the gallery photos for Canon EOS 400D & Pentax K-x. The entire galleries are viewable at Canon 400D Gallery & Pentax K-x Gallery.

For those who are aiming to carry your camera, you have to consider its weight and measurements.

Remember, the weight of an ILC will vary depending on the lens you are using during that time. Here is the front view scale comparison of the 400D compared to the K-x.

Looking at size and weight, the portability score of the 400D and K-x is 69 and 69 respectively.

Often, its tough to imagine the contrast in sensor sizing only by looking through a spec sheet. The visual here might give you a stronger sense of the sensor sizes in the 400D and K-x.

Clearly, both of these cameras offer the same exact sensor sizing albeit different megapixels. You can count on the Pentax K-x to render greater detail due to its extra 2 Megapixels. Higher resolution will also make it easier to crop shots a little more aggressively. The older 400D will be behind with regard to sensor innovation.
