Olympus E-400 vs Pentax K-x

Lets look a bit more closely at the Olympus E-400 versus Pentax K-x, both Entry-Level DSLR digital cameras by companies Olympus and Pentax. The resolution of the E-400 (10MP) and the K-x (12MP) is relatively well matched but the E-400 (Four Thirds) and K-x (APS-C) posses totally different sensor sizes.

The E-400 was announced 4 years before the K-x which is quite a serious difference as far as tech is concerned. Both cameras have the same body design (Compact SLR).

Before we go into a complete comparison, here is a short synopsis of how the E-400 matches up against the K-x with respect to portability, imaging, features and an overall mark.

The following is a preview of the gallery photos for Olympus E-400 & Pentax K-x. The whole galleries are provided at Olympus E-400 Gallery & Pentax K-x Gallery.

When you are going to travel with your camera, you need to consider its weight and size.

Often, it's difficult to see the difference between sensor dimensions just by looking at a spec sheet. The picture below will help provide you a better sense of the sensor sizes in the E-400 and K-x.

As you can see, the 2 cameras have different megapixels and different sensor dimensions. The E-400 using its tinier sensor will make getting shallower DOF more challenging and the Pentax K-x will resolve extra detail with its extra 2MP. Higher resolution can also help you crop pictures a bit more aggressively. The more aged E-400 is going to be disadvantaged when it comes to sensor technology.
