Olympus E-P3 vs Olympus 1s

Following is a comprehensive review of the Olympus E-P3 and Olympus 1s, one is a Entry-Level Mirrorless and the latter is a Small Sensor Superzoom and they are both offered by Olympus. The sensor resolution of the E-P3 (12MP) and the 1s (12MP) is pretty similar but the E-P3 (Four Thirds) and 1s (1/1.7") come with different sensor sizes.

The E-P3 was introduced 4 years prior to the 1s which is quite a large gap as far as technology is concerned. Each of these cameras offer different body type with the Olympus E-P3 being a Rangefinder-style mirrorless camera and the Olympus 1s being a SLR-like (bridge) camera.

Before diving in to a full comparison, below is a concise overview of how the E-P3 grades vs the 1s when considering portability, imaging, features and an overall score.

This is a preview of the gallery images for Olympus PEN E-P3 and Olympus Stylus 1s. The whole galleries are provided at Olympus E-P3 Gallery and Olympus 1s Gallery.

In case you're looking to carry around your camera, you have to take into account its weight and measurements. The Olympus E-P3 offers external measurements of 122mm x 69mm x 34mm (4.8" x 2.7" x 1.3") accompanied by a weight of 369 grams (0.81 lbs) while the Olympus 1s has proportions 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 vary dependant on the lens you are working with at the time. Below is the front view physical size comparison of the E-P3 and the 1s.

Taking into account dimensions and weight, the portability grade of the E-P3 and 1s is 86 and 79 respectively.

More often than not, its tough to visualize the contrast between sensor sizes just by reviewing a spec sheet. The picture underneath will give you a far better sense of the sensor measurements in the E-P3 and 1s.

Clearly, each of these cameras enjoy the same exact megapixel count albeit different sensor sizes. The E-P3 contains the bigger sensor which should make achieving bokeh simpler. The more aged E-P3 is going to be behind when it comes to sensor innovation.
