Olympus E-PM1 vs Panasonic G100

Below is a in depth review of the Olympus E-PM1 vs Panasonic G100, both Entry-Level Mirrorless digital cameras by manufacturers Olympus and Panasonic. There exists a crucial gap between the resolutions of the E-PM1 (12MP) and G100 (20MP) but both cameras offer the identical sensor size (Four Thirds).

The E-PM1 was introduced 9 years before the G100 and that is quite a serious gap as far as technology is concerned. Each of the cameras feature different body design with the Olympus E-PM1 being a Rangefinder-style mirrorless camera and the Panasonic G100 being a SLR-style mirrorless camera.

Before going right into a thorough comparison, here is a simple view of how the E-PM1 scores against the G100 with regards to portability, imaging, features and an overall grade.

This is a sample of the gallery pictures for Olympus PEN E-PM1 and Panasonic Lumix DC-G100. The whole galleries are available at Olympus E-PM1 Gallery and Panasonic G100 Gallery.

For anybody who is intending to lug around your camera, you will have to think about its weight and dimensions. The Olympus E-PM1 comes with outer dimensions of 110mm x 64mm x 34mm (4.3" x 2.5" x 1.3") with a weight of 265 grams (0.58 lbs) whilst the Panasonic G100 has dimensions of 116mm x 83mm x 54mm (4.6" x 3.3" x 2.1") accompanied by a weight of 352 grams (0.78 lbs).

More often than not, it is very tough to visualise the difference between sensor measurements simply by checking technical specs. The visual here will offer you a more clear sense of the sensor sizes in the E-PM1 and G100.

As you have seen, both of the cameras feature the identical sensor size but not the same MP. You should anticipate the Panasonic G100 to give you greater detail using its extra 8 Megapixels. Greater resolution will let you crop pics way more aggressively. The older E-PM1 is going to be disadvantaged when it comes to sensor technology.
