Photography Glossary

The E-PM2 was unveiled 23 months prior to the TG-4 making the cameras a generation apart from one another. Each of the cameras come with different body type with the Olympus E-PM2 being a Rangefinder-style mirrorless camera and the Olympus TG-4 being a Compact camera.

Before we go straight into a comprehensive comparison, below is a brief summary of how the E-PM2 matches up vs the TG-4 in the way of portability, imaging, features and an overall grade.

Here is a sample of the gallery pictures for Olympus PEN E-PM2 & Olympus Tough TG-4. The full galleries are viewable at Olympus E-PM2 Gallery & Olympus TG-4 Gallery.

If you are aiming to lug around your camera regularly, you need to factor in its weight and measurements.
