The E-1 was announced 6 years before the P80 and that is a fairly serious gap as far as camera tech is concerned. The two cameras offer different body type with the Olympus E-1 being a Large SLR camera and the Pentax P80 being a Compact camera.

Before getting through a step-by-step comparison, below is a brief introduction of how the E-1 matches up against the P80 with regards to portability, imaging, features and an overall grade.

The following is a sample of the gallery pictures for Olympus E-1 and Pentax Optio P80. The whole galleries are viewable at Olympus E-1 Gallery and Pentax P80 Gallery.

Often, it is very difficult to visualize the gap in sensor measurements simply by seeing specifications. The graphic below might provide you a far better sense of the sensor dimensions in the E-1 and P80.

To sum up, each of these cameras offer different resolutions and different sensor measurements. The E-1 having a larger sensor is going to make shooting shallow depth of field less difficult and the Pentax P80 will produce greater detail with its extra 7MP. Greater resolution will also help you crop photos a little more aggressively. The older E-1 will be disadvantaged in sensor tech.
