The E-400 was announced 3 years prior to the E-P1 and that is quite a big difference as far as tech is concerned. Both of the cameras come with different body type with the Olympus E-400 being a Compact SLR camera and the Olympus E-P1 being a Rangefinder-style mirrorless camera.

Before getting through a detailed comparison, below is a quick view of how the E-400 grades against the E-P1 in regards to portability, imaging, features and an overall rating.

Oftentimes, it's difficult to visualise the difference between sensor sizing merely by reviewing a spec sheet. The photograph here will help give you a greater sense of the sensor sizing in the E-400 and E-P1.

As you can see, the 2 cameras posses the exact same sensor measurements albeit not the same megapixels. You can expect the Olympus E-P1 to deliver greater detail with its extra 2 Megapixels. Higher resolution will also enable you to crop pictures somewhat more aggressively. The older E-400 is going to be behind in sensor innovation.
