The E-510 was manufactured 14 years prior to the K-3 III and that is quite a large gap as far as technology is concerned. The two cameras offer the identical body type (Mid-size SLR).

Before we go in to a thorough comparison, below is a brief synopsis of how the E-510 scores vs the K-3 III for portability, imaging, features and an overall grade.

Following is a sample of the gallery pictures for Olympus E-510 and Pentax K-3 Mark III. The entire galleries are viewable at Olympus E-510 Gallery and Pentax K-3 III Gallery.

If you're aiming to lug around your camera regularly, you have to factor its weight and dimensions.

Normally, its tough to imagine the difference between sensor measurements only by going over specs. The graphic below will provide you a greater sense of the sensor sizing in the E-510 and K-3 III.

All in all, both of these cameras enjoy different megapixels and different sensor measurements. The E-510 featuring a tinier sensor is going to make shooting shallower DOF more difficult and the Pentax K-3 III will deliver more detail due to its extra 16 Megapixels. Greater resolution will also make it easier to crop photos far more aggressively. The older E-510 is going to be disadvantaged when it comes to sensor innovation.
