The WG-3 was manufactured 3 years later than the A500 and that is quite a significant gap as far as tech is concerned. Both cameras feature different body design with the Pentax WG-3 being a Compact camera and the Sony A500 being a Compact SLR camera.

Before we go straight to a full comparison, here is a short introduction of how the WG-3 grades vs the A500 when considering portability, imaging, features and an overall grade.

Following is a sample of the gallery pics for Pentax WG-3 and Sony Alpha DSLR-A500. The entire galleries are provided at Pentax WG-3 Gallery and Sony A500 Gallery.

Generally, its tough to see the contrast between sensor measurements only by looking at a spec sheet. The visual below will help provide you a better sense of the sensor sizes in the WG-3 and A500.

Clearly, the 2 cameras come with different resolutions and different sensor measurements. The WG-3 due to its tinier sensor will make shooting shallow DOF harder and the Pentax WG-3 will give greater detail due to its extra 4 Megapixels. Greater resolution will allow you to crop images a good deal more aggressively. The fresher WG-3 will have a benefit in sensor technology.
