Canon G3 X vs Olympus E-P3

Below is a thorough assessment of the Canon G3 X versus Olympus E-P3, one being a Large Sensor Superzoom and the latter is a Entry-Level Mirrorless by companies Canon and Olympus. There exists a sizeable gap between the sensor resolutions of the G3 X (20MP) and E-P3 (12MP) and the G3 X (1") and E-P3 (Four Thirds) posses totally different sensor size.

The G3 X was revealed 3 years later than the E-P3 and that is quite a large gap as far as technology is concerned. Both of the cameras have different body design with the Canon G3 X being a SLR-like (bridge) camera and the Olympus E-P3 being a Rangefinder-style mirrorless camera.

Before going right into a more detailed comparison, here is a concise highlight of how the G3 X matches up against the E-P3 when considering portability, imaging, features and an overall grade.

Remember, the weight of an Interchangeable Lens Camera will differ based on the lens you have chosen at the time. The following is a front view physical size comparison of the G3 X versus the E-P3.

Considering dimensions and weight, the portability score of the G3 X and E-P3 is 60 and 86 respectively.

Sometimes, its difficult to envision the difference between sensor measurements just by reviewing technical specs. The visual underneath might provide you a stronger sense of the sensor dimensions in the G3 X and E-P3.

As you have seen, both of those cameras have different megapixels and different sensor measurements. The G3 X using its tinier sensor will make shooting shallow depth of field trickier and the Canon G3 X will offer you more detail because of its extra 8 Megapixels. Higher resolution will also enable you to crop shots a bit more aggressively. The more recent G3 X is going to have a benefit in sensor tech.
