The E-30 was manufactured 6 years earlier than the K-S2 and that is a fairly big gap as far as camera tech is concerned. Both of the cameras come with different body type with the Olympus E-30 being a Mid-size SLR camera and the Pentax K-S2 being a Compact SLR camera.

Before diving through a step-by-step comparison, below is a short synopsis of how the E-30 scores vs the K-S2 with respect to portability, imaging, features and an overall grade.

Here is a sample of the gallery pictures for Olympus E-30 and Pentax K-S2. The entire galleries are provided at Olympus E-30 Gallery and Pentax K-S2 Gallery.

In case you're going to lug around your camera frequently, you'll have to factor its weight and size.

Bear in mind, the weight of an Interchangeable Lens Camera will vary based on the lens you use at that time. Following is the front view scale comparison of the E-30 versus the K-S2.

Looking at size and weight, the portability score of the E-30 and K-S2 is 60 and 64 respectively.

In many cases, it is tough to visualize the difference in sensor measurements purely by seeing a spec sheet. The graphic here will give you a stronger sense of the sensor measurements in the E-30 and K-S2.

As you can see, each of these cameras posses different megapixel count and different sensor measurements. The E-30 due to its smaller sensor is going to make achieving shallow depth of field trickier and the Pentax K-S2 will provide more detail due to its extra 8 Megapixels. Greater resolution will enable you to crop photos somewhat more aggressively. The older E-30 will be disadvantaged with regard to sensor tech.
