Olympus E-PL1s vs Pentax Efina

Its time to look more closely at the Olympus E-PL1s and Pentax Efina, one is a Entry-Level Mirrorless and the other is a Ultracompact by rivals Olympus and Pentax. The image resolution of the E-PL1s (12MP) and the Efina (14MP) is fairly well matched but the E-PL1s (Four Thirds) and Efina (1/2.3") come with different sensor dimensions.

The E-PL1s was introduced 3 years prior to the Efina which is quite a significant gap as far as tech is concerned. Each of the cameras come with different body type with the Olympus E-PL1s being a Rangefinder-style mirrorless camera and the Pentax Efina being a Ultracompact camera.

Before diving in to a more detailed comparison, below is a simple highlight of how the E-PL1s matches up vs the Efina when considering portability, imaging, features and an overall score.

Factoring in size and weight, the portability grade of the E-PL1s and Efina is 86 and 97 respectively.

Generally, it is tough to visualize the gap between sensor sizes just by checking technical specs. The pic underneath should give you a better sense of the sensor sizing in the E-PL1s and Efina.

As you can tell, the two cameras have got different megapixels and different sensor sizes. The E-PL1s with its larger sensor is going to make getting shallower depth of field easier and the Pentax Efina will resolve greater detail using its extra 2 Megapixels. Greater resolution will also let you crop images much more aggressively. The more aged E-PL1s is going to be behind in sensor tech.
