The R-D1 was launched 8 years prior to the E-PM1 and that is quite a serious gap as far as tech is concerned. Both of these cameras offer the identical body type (Rangefinder-style mirrorless).

Before going through a complete comparison, below is a quick view of how the R-D1 grades against the E-PM1 with regards to portability, imaging, features and an overall rating.

Here is a sample of the gallery pictures for Epson R-D1 and Olympus PEN E-PM1. The complete galleries are available at Epson R-D1 Gallery and Olympus E-PM1 Gallery.

Usually, it can be difficult to visualize the gap between sensor sizing only by looking at specs. The photograph below should provide you a clearer sense of the sensor sizing in the R-D1 and E-PM1.

All in all, the 2 cameras offer different megapixels and different sensor sizing. The R-D1 due to its larger sensor is going to make achieving shallower DOF less difficult and the Olympus E-PM1 will give greater detail utilizing its extra 6 Megapixels. Greater resolution will also let you crop photos a little more aggressively. The older R-D1 is going to be behind in sensor innovation.
