On this page, we will be looking at the Olympus E-300 vs Pentax K-x, former is a Advanced DSLR while the latter is a Entry-Level DSLR by competitors Olympus and Pentax. There exists a large gap between the sensor resolutions of the E-300 (8MP) and K-x (12MP) and the E-300 (Four Thirds) and K-x (APS-C) provide totally different sensor sizing.

The E-300 was unveiled 6 years before the K-x which is quite a serious difference as far as technology is concerned. Each of these cameras have different body design with the Olympus E-300 being a Mid-size SLR camera and the Pentax K-x being a Compact SLR camera.

Before diving straight to a more detailed comparison, here is a quick summation of how the E-300 grades against the K-x when it comes to portability, imaging, features and an overall score.

Following is a preview of the gallery images for Olympus E-300 & Pentax K-x. The full galleries are provided at Olympus E-300 Gallery & Pentax K-x Gallery.

Normally, its hard to visualise the difference between sensor sizes purely by reading through specs. The image below will help offer you a far better sense of the sensor dimensions in the E-300 and K-x.

All in all, both of these cameras have different megapixels and different sensor sizes. The E-300 with its tinier sensor will make shooting shallower DOF more difficult and the Pentax K-x will give you more detail having an extra 4MP. Higher resolution can also let you crop shots a bit more aggressively. The more aged E-300 is going to be disadvantaged when it comes to sensor technology.
