The TG-820 iHS was revealed 2 years later than the GF1 and that is quite a big difference as far as technology is concerned. Both the cameras feature different body design with the Olympus TG-820 iHS being a Compact camera and the Panasonic GF1 being a Rangefinder-style mirrorless camera.

Before getting right into a step-by-step comparison, here is a concise summation of how the TG-820 iHS scores against the GF1 in the way of portability, imaging, features and an overall grade.

Quite often, it is very hard to visualise the gap between sensor measurements simply by looking at specs. The graphic below may give you a better sense of the sensor sizing in the TG-820 iHS and GF1.

As you can plainly see, both of the cameras feature the identical megapixels albeit not the same sensor measurements. The TG-820 iHS provides the tinier sensor which will make getting shallower DOF harder. The more modern TG-820 iHS is going to have a benefit when it comes to sensor tech.
