Olympus E-P7 vs Sony A3000

Let's look a little more in depth at the Olympus E-P7 versus Sony A3000, both Entry-Level Mirrorless cameras by manufacturers Olympus and Sony. The image resolution of the E-P7 (20MP) and the A3000 (20MP) is very close but the E-P7 (Four Thirds) and A3000 (APS-C) use different sensor sizes.

The E-P7 was brought out 7 years later than the A3000 and that is a fairly big gap as far as camera technology is concerned. Each of the cameras offer different body type with the Olympus E-P7 being a Rangefinder-style mirrorless camera and the Sony A3000 being a SLR-style mirrorless camera.

Before going through a comprehensive comparison, below is a brief summation of how the E-P7 matches up against the A3000 in terms of portability, imaging, features and an overall grade.

Don't forget, the weight of an Interchangeable Lens Camera will vary dependant on the lens you use at that time. Following is the front view size comparison of the E-P7 and the A3000.

Looking at dimensions and weight, the portability grade of the E-P7 and A3000 is 86 and 69 respectively.

Typically, its tough to picture the difference in sensor measurements purely by viewing technical specs. The photograph below should offer you a much better sense of the sensor dimensions in the E-P7 and A3000.

As you can tell, both the cameras offer the same exact megapixel count but different sensor measurements. The E-P7 provides the smaller sensor which is going to make achieving shallower depth of field more challenging. The younger E-P7 provides a benefit with regard to sensor technology.
