The E-PM1 was released 5 years earlier than the Quattro which is quite a big gap as far as technology is concerned. Each of the cameras have the same body design (Rangefinder-style mirrorless).

Before diving right into a full comparison, here is a simple view of how the E-PM1 scores vs the Quattro for portability, imaging, features and an overall mark.

The following is a preview of the gallery images for Olympus PEN E-PM1 and Sigma sd Quattro. The complete galleries are viewable at Olympus E-PM1 Gallery and Sigma Quattro Gallery.

More often than not, its tough to picture the difference between sensor dimensions simply by reading through specs. The picture below will give you a stronger sense of the sensor sizes in the E-PM1 and Quattro.

As you can plainly see, both the cameras have different megapixel count and different sensor dimensions. The E-PM1 because of its tinier sensor is going to make achieving shallower depth of field more challenging and the Sigma Quattro will resolve more detail as a result of its extra 17MP. Higher resolution will make it easier to crop shots a bit more aggressively. The more aged E-PM1 is going to be behind in sensor technology.
