Pentax P70 vs Pentax WG-1 GPS

On this page, we will be reviewing the Pentax P70 vs Pentax WG-1 GPS, one being a Ultracompact and the latter is a Waterproof and both are manufactured by Pentax. The sensor resolution of the P70 (12MP) and the WG-1 GPS (14MP) is pretty well matched and both cameras provide the same sensor sizes (1/2.3").

Photography Glossary

The P70 was revealed 3 years before the WG-1 GPS and that is quite a large gap as far as technology is concerned. Both the cameras have different body design with the Pentax P70 being a Ultracompact camera and the Pentax WG-1 GPS being a Compact camera.

Before going straight to a in-depth comparison, here is a concise synopsis of how the P70 scores against the WG-1 GPS when it comes to portability, imaging, features and an overall grade.

Below is a preview of the gallery images for Pentax Optio P70 and Pentax Optio WG-1 GPS. The full galleries are viewable at Pentax P70 Gallery and Pentax WG-1 GPS Gallery.

If you're looking to lug around your camera, you are going to need to take into account its weight and volume. The Pentax P70 features outside measurements of 97mm x 54mm x 22mm (3.8" x 2.1" x 0.9") along with a weight of 155 grams (0.34 lbs) whilst the Pentax WG-1 GPS has sizing of 116mm x 59mm x 29mm (4.6" x 2.3" x 1.1") with a weight of 167 grams (0.37 lbs).

Remember that, the weight of an Interchangeable Lens Camera will differ dependant on the lens you have chosen at that moment. Following is a front view measurement comparison of the P70 vs the WG-1 GPS.

Using dimensions and weight, the portability grade of the P70 and WG-1 GPS is 95 and 93 respectively.

Normally, it is very difficult to visualise the gap between sensor measurements only by looking at technical specs. The graphic underneath should give you a far better sense of the sensor measurements in the P70 and WG-1 GPS.

As you can tell, each of the cameras have the same sensor dimensions albeit not the same megapixels. You should expect the Pentax WG-1 GPS to give you greater detail because of its extra 2 Megapixels. Higher resolution can also make it easier to crop shots a bit more aggressively. The older P70 is going to be disadvantaged with regard to sensor technology.
