Olympus E-P3 vs Pentax Q

In this write-up, we will be reviewing the Olympus E-P3 vs Pentax Q, both Entry-Level Mirrorless digital cameras by competitors Olympus and Pentax. The image resolution of the E-P3 (12MP) and the Q (12MP) is pretty similar but the E-P3 (Four Thirds) and Q (1/2.3") feature different sensor sizes.

The E-P3 was introduced 2 months later than the Q so they are both of a similar age. Both the cameras offer the identical body type (Rangefinder-style mirrorless).

Before going straight into a step-by-step comparison, below is a brief summary of how the E-P3 scores vs the Q in the way of portability, imaging, features and an overall grade.

Here is a preview of the gallery images for Olympus PEN E-P3 & Pentax Q. The whole galleries are available at Olympus E-P3 Gallery & Pentax Q Gallery.

Bear in mind, the weight of an ILC will change based on the lens you are working with at the time. Here is the front view size comparison of the E-P3 compared to the Q.

Taking into account size and weight, the portability score of the E-P3 and Q is 86 and 93 respectively.

In many cases, it is hard to visualize the difference between sensor measurements merely by reviewing a spec sheet. The graphic below may give you a better sense of the sensor dimensions in the E-P3 and Q.

Clearly, both cameras offer the same exact resolution albeit different sensor measurements. The E-P3 has got the bigger sensor which is going to make achieving shallower DOF simpler.
