Olympus 1s vs Pentax VS20

Let's look more closely at the Olympus 1s and Pentax VS20, both Small Sensor Superzoom digital cameras by brands Olympus and Pentax. There exists a noticeable gap between the sensor resolutions of the 1s (12MP) and VS20 (16MP) and the 1s (1/1.7") and VS20 (1/2.3") boast different sensor measurements.

The 1s was manufactured 3 years later than the VS20 and that is quite a sizable difference as far as technology is concerned. Each of these cameras have different body design with the Olympus 1s being a SLR-like (bridge) camera and the Pentax VS20 being a Compact camera.

Before going into a complete comparison, here is a concise introduction of how the 1s grades against the VS20 with regard to portability, imaging, features and an overall grade.

Here is a sample of the gallery pictures for Olympus Stylus 1s & Pentax Optio VS20. The entire galleries are provided at Olympus 1s Gallery & Pentax VS20 Gallery.

In case you're aiming to lug around your camera, you will have to consider its weight and size. The Olympus 1s offers physical measurements of 116mm x 87mm x 57mm (4.6" x 3.4" x 2.2") accompanied by a weight of 402 grams (0.89 lbs) whilst the Pentax VS20 has specifications of 111mm x 61mm x 38mm (4.4" x 2.4" x 1.5") along with a weight of 235 grams (0.52 lbs).

Bear in mind, the weight of an ILC will differ depending on the lens you have chosen at that moment. Below is a front view measurements comparison of the 1s and the VS20.

Taking into consideration dimensions and weight, the portability grade of the 1s and VS20 is 79 and 90 respectively.

Quite often, it is very tough to imagine the difference between sensor measurements just by reviewing a spec sheet. The visual below may offer you a clearer sense of the sensor measurements in the 1s and VS20.

Clearly, both of these cameras provide different resolutions and different sensor measurements. The 1s because of its larger sensor is going to make achieving shallower depth of field less difficult and the Pentax VS20 will deliver greater detail due to its extra 4MP. Greater resolution can also enable you to crop photos more aggressively. The more recent 1s should have an edge with regard to sensor technology.
