Panasonic G3 vs Pentax WG-2 GPS

The following is a extended review of the Panasonic G3 versus Pentax WG-2 GPS, one is a Entry-Level Mirrorless and the latter is a Waterproof by rivals Panasonic and Pentax. The resolution of the G3 (16MP) and the WG-2 GPS (16MP) is pretty similar but the G3 (Four Thirds) and WG-2 GPS (1/2.3") possess totally different sensor measurements.

The G3 was announced 7 months prior to the WG-2 GPS which means that they are of a similar generation. Both of these cameras offer different body type with the Panasonic G3 being a SLR-style mirrorless camera and the Pentax WG-2 GPS being a Compact camera.

Before we go in to a step-by-step comparison, below is a concise synopsis of how the G3 grades versus the WG-2 GPS when it comes to portability, imaging, features and an overall mark.

The following is a preview of the gallery images for Panasonic Lumix DMC-G3 and Pentax Optio WG-2 GPS. The whole galleries are viewable at Panasonic G3 Gallery and Pentax WG-2 GPS Gallery.

If you're going to travel with your camera often, you will have to factor its weight and proportions. The Panasonic G3 features outside dimensions of 115mm x 84mm x 47mm (4.5" x 3.3" x 1.9") accompanied by a weight of 336 grams (0.74 lbs) and the Pentax WG-2 GPS has measurements of 122mm x 61mm x 30mm (4.8" x 2.4" x 1.2") along with a weight of 198 grams (0.44 lbs).

Don't forget, the weight of an Interchangeable Lens Camera will differ depending on the lens you select at that moment. Underneath is the front view over all size comparison of the G3 compared to the WG-2 GPS.

Taking into account dimensions and weight, the portability grade of the G3 and WG-2 GPS is 83 and 91 respectively.

Normally, it is difficult to see the gap between sensor dimensions merely by going over a spec sheet. The image here may give you a greater sense of the sensor sizes in the G3 and WG-2 GPS.

As you can see, both the cameras enjoy the same exact megapixels albeit not the same sensor dimensions. The G3 offers the bigger sensor which is going to make getting shallow depth of field less difficult. The more aged G3 is going to be disadvantaged with regard to sensor innovation.
