The following is a detailed assessment of the Olympus E-P7 and Panasonic G1, both Entry-Level Mirrorless cameras by rivals Olympus and Panasonic. There exists a substantial gap among the sensor resolutions of the E-P7 (20MP) and G1 (12MP) but both cameras have the identical sensor sizing (Four Thirds).

The E-P7 was announced 12 years after the G1 which is a fairly big difference as far as camera technology is concerned. Both the cameras feature different body design with the Olympus E-P7 being a Rangefinder-style mirrorless camera and the Panasonic G1 being a SLR-style mirrorless camera.

Before diving straight to a step-by-step comparison, here is a short summation of how the E-P7 scores versus the G1 in relation to portability, imaging, features and an overall mark.

When you are aiming to travel with your camera often, you are going to need to think about its weight and dimensions.

Take into consideration, the weight of an ILC will vary based on the lens you are working with at that time. Below is a front view sizing comparison of the E-P7 against the G1.

Taking into account dimensions and weight, the portability rating of the E-P7 and G1 is 86 and 82 respectively.

Typically, it is very difficult to visualize the gap in sensor dimensions merely by seeing a spec sheet. The picture here may provide you a stronger sense of the sensor sizes in the E-P7 and G1.

As you can see, each of the cameras feature the identical sensor size but different resolution. You can anticipate the Olympus E-P7 to produce greater detail with its extra 8 Megapixels. Greater resolution will also enable you to crop images way more aggressively. The fresher E-P7 provides a benefit with regard to sensor technology.
