Olympus 1 vs Pentax K-S1

Its time to look a little more in depth at the Olympus 1 and Pentax K-S1, one being a Small Sensor Superzoom and the other is a Advanced DSLR by companies Olympus and Pentax. There exists a huge gap among the sensor resolutions of the 1 (12MP) and K-S1 (20MP) and the 1 (1/1.7") and K-S1 (APS-C) posses different sensor sizing.

The 1 was released 9 months prior to the K-S1 and they are both of a similar generation. Both of these cameras have different body design with the Olympus 1 being a SLR-like (bridge) camera and the Pentax K-S1 being a Mid-size SLR camera.

Before diving straight to a full comparison, here is a concise highlight of how the 1 grades against the K-S1 when considering portability, imaging, features and an overall grade.

Following is a sample of the gallery pictures for Olympus Stylus 1 and Pentax K-S1. The complete galleries are viewable at Olympus 1 Gallery and Pentax K-S1 Gallery.

In case you're going to lug around your camera, you'll need to factor in its weight and measurements. The Olympus 1 provides external measurements of 116mm x 87mm x 57mm (4.6" x 3.4" x 2.2") along with a weight of 402 grams (0.89 lbs) and the Pentax K-S1 has proportions of 121mm x 93mm x 70mm (4.8" x 3.7" x 2.8") and a weight of 558 grams (1.23 lbs).

Always remember, the weight of an Interchangeable Lens Camera will change depending on the lens you select at that moment. Underneath is a front view dimensions comparison of the 1 versus the K-S1.

Considering dimensions and weight, the portability score of the 1 and K-S1 is 79 and 69 respectively.

More often than not, it is very tough to visualize the gap in sensor measurements just by going through technical specs. The graphic here might provide you a much better sense of the sensor sizing in the 1 and K-S1.

As you can tell, each of these cameras have different resolutions and different sensor measurements. The 1 due to its smaller sensor is going to make getting shallower depth of field harder and the Pentax K-S1 will show greater detail as a result of its extra 8MP. Greater resolution will allow you to crop pics a bit more aggressively. The older 1 will be behind when it comes to sensor innovation.
