Its time to look more closely at the Olympus E-P3 and Panasonic GH4, one is a Entry-Level Mirrorless and the latter is a Pro Mirrorless by competitors Olympus and Panasonic.

The E-P3 was introduced 3 years prior to the GH4 which is quite a big gap as far as technology is concerned. The two cameras have different body design with the Olympus E-P3 being a Rangefinder-style mirrorless camera and the Panasonic GH4 being a SLR-style mirrorless camera.

Before delving right into a thorough comparison, here is a simple overview of how the E-P3 grades versus the GH4 with respect to portability, imaging, features and an overall mark.

Normally, it's difficult to visualize the difference between sensor dimensions only by reviewing specifications. The pic underneath will provide you a far better sense of the sensor dimensions in the E-P3 and GH4.

Plainly, both the cameras have the same sensor dimensions albeit different MP. You should count on the Panasonic GH4 to offer you more detail using its extra 4MP. Higher resolution will also let you crop shots a bit more aggressively. The more aged E-P3 is going to be disadvantaged in sensor technology.
