Olympus E-P1 vs Olympus 1s

Lets look a little more in depth at the Olympus E-P1 and Olympus 1s, one being a Entry-Level Mirrorless and the other is a Small Sensor Superzoom and both of them are built by Olympus. The image resolution of the E-P1 (12MP) and the 1s (12MP) is very close but the E-P1 (Four Thirds) and 1s (1/1.7") use different sensor sizes.

Photography Glossary

The E-P1 was revealed 6 years prior to the 1s and that is a fairly large gap as far as camera technology is concerned. Each of the cameras offer different body type with the Olympus E-P1 being a Rangefinder-style mirrorless camera and the Olympus 1s being a SLR-like (bridge) camera.

Before we go through a complete comparison, below is a short view of how the E-P1 scores against the 1s when it comes to portability, imaging, features and an overall grade.

Following is a sample of the gallery pics for Olympus PEN E-P1 and Olympus Stylus 1s. The full galleries are provided at Olympus E-P1 Gallery and Olympus 1s Gallery.

When you are planning to lug around your camera, you need to take into account its weight and proportions. The Olympus E-P1 offers physical measurements of 121mm x 70mm x 36mm (4.8" x 2.8" x 1.4") and a weight of 355 grams (0.78 lbs) while the Olympus 1s has measurements of 116mm x 87mm x 57mm (4.6" x 3.4" x 2.2") and a weight of 402 grams (0.89 lbs).

Take into consideration, the weight of an Interchangeable Lens Camera will differ depending on the lens you are using at the time. The following is the front view measurements comparison of the E-P1 vs the 1s.

Taking into account dimensions and weight, the portability rating of the E-P1 and 1s is 86 and 79 respectively.

Typically, it is very hard to picture the difference in sensor measurements simply by researching specs. The graphic below will provide you a better sense of the sensor sizing in the E-P1 and 1s.

As you can plainly see, both the cameras enjoy the same exact megapixel count but different sensor measurements. The E-P1 contains the larger sensor which will make obtaining shallower depth of field less difficult. The older E-P1 will be behind in sensor tech.
