Pentax WG-2 vs Pentax Q-S1

Let's look much closer at the Pentax WG-2 vs Pentax Q-S1, one being a Waterproof and the other is a Entry-Level Mirrorless and both are designed by Pentax. There exists a big gap among the sensor resolutions of the WG-2 (16MP) and Q-S1 (12MP) and the WG-2 (1/2.3") and Q-S1 (1/1.7") boast different sensor measurements.

The WG-2 was launched 3 years earlier than the Q-S1 and that is a fairly big gap as far as camera technology is concerned. Both of the cameras have different body design with the Pentax WG-2 being a Compact camera and the Pentax Q-S1 being a Rangefinder-style mirrorless camera.

Before diving straight to a step-by-step comparison, here is a brief overview of how the WG-2 scores vs the Q-S1 in the way of portability, imaging, features and an overall rating.

Following is a sample of the gallery pictures for Pentax Optio WG-2 and Pentax Q-S1. The complete galleries are viewable at Pentax WG-2 Gallery and Pentax Q-S1 Gallery.

If you're aiming to carry your camera, you'll need to take into account its weight and measurements. The Pentax WG-2 has outside dimensions of 122mm x 61mm x 30mm (4.8" x 2.4" x 1.2") and a weight of 192 grams (0.42 lbs) whilst the Pentax Q-S1 has proportions of 105mm x 58mm x 34mm (4.1" x 2.3" x 1.3") accompanied by a weight of 203 grams (0.45 lbs).

Remember, the weight of an Interchangeable Lens Camera will change dependant on the lens you have at the time. Below is a front view overall size comparison of the WG-2 and the Q-S1.

Considering dimensions and weight, the portability rating of the WG-2 and Q-S1 is 91 and 92 respectively.

More often than not, it's hard to visualize the difference in sensor sizing simply by checking out a spec sheet. The visual underneath may provide you a much better sense of the sensor sizes in the WG-2 and Q-S1.

Clearly, the 2 cameras have different megapixel count and different sensor sizing. The WG-2 due to its smaller sensor is going to make achieving shallower DOF more difficult and the Pentax WG-2 will provide more detail utilizing its extra 4MP. Greater resolution can also enable you to crop photos a bit more aggressively. The older WG-2 will be behind when it comes to sensor innovation.
