The E-PM1 was introduced 24 months before the 1 making the cameras a generation apart from each other. Each of the cameras offer different body type with the Olympus E-PM1 being a Rangefinder-style mirrorless camera and the Olympus 1 being a SLR-like (bridge) camera.

Before we go in to a thorough comparison, below is a simple highlight of how the E-PM1 matches up against the 1 with respect to portability, imaging, features and an overall rating.

The following is a sample of the gallery pics for Olympus PEN E-PM1 & Olympus Stylus 1. The whole galleries are viewable at Olympus E-PM1 Gallery & Olympus 1 Gallery.

For those who are intending to carry your camera, you will need to factor its weight and size.
