Olympus E-PL1 vs Pentax Q-S1 Overview

Let's look more closely at the Olympus E-PL1 versus Pentax Q-S1, both Entry-Level Mirrorless digital cameras by manufacturers Olympus and Pentax. The resolution of the E-PL1 (12MP) and the Q-S1 (12MP) is pretty well matched but the E-PL1 (Four Thirds) and Q-S1 (1/1.7") offer different sensor sizing.

The E-PL1 was manufactured 5 years earlier than the Q-S1 and that is quite a large gap as far as tech is concerned. Both the cameras have the same body design (Rangefinder-style mirrorless).

Before we go straight to a step-by-step comparison, here is a simple summary of how the E-PL1 grades versus the Q-S1 in regards to portability, imaging, features and an overall rating.

Olympus E-PL1 vs Pentax Q-S1 Sensor Comparison

		

		

			
Usually, it's tough to picture the contrast between sensor sizing purely by reading through specs. The visual here should offer you a stronger sense of the sensor dimensions in the E-PL1 and Q-S1.
As you can plainly see, both cameras have the same resolution albeit different sensor sizing. The E-PL1 uses the bigger sensor which should make achieving shallow DOF simpler. The older E-PL1 is going to be behind in sensor technology.
