The E-3 was announced 5 years later than the SD9 and that is quite a large gap as far as tech is concerned. Both of these cameras offer the identical body type (Mid-size SLR).

Before we go in to a step-by-step comparison, below is a quick overview of how the E-3 scores versus the SD9 with regard to portability, imaging, features and an overall grade.

Below is a sample of the gallery pics for Olympus E-3 and Sigma SD9. The whole galleries are provided at Olympus E-3 Gallery and Sigma SD9 Gallery.

Usually, it is very tough to visualize the gap between sensor measurements only by reading through specifications. The visual underneath will help offer you a far better sense of the sensor sizes in the E-3 and SD9.

To sum up, the 2 cameras offer different megapixels and different sensor measurements. The E-3 using its tinier sensor is going to make achieving shallower depth of field tougher and the Olympus E-3 will give you greater detail with its extra 7 Megapixels. Greater resolution can also let you crop photos a little more aggressively. The fresher E-3 provides an edge when it comes to sensor technology.
