Pentax K-7 vs Pentax WG-1 GPS

Here, we are reviewing the Pentax K-7 and Pentax WG-1 GPS, one being a Advanced DSLR and the other is a Waterproof and they are both designed by Pentax. The sensor resolution of the K-7 (15MP) and the WG-1 GPS (14MP) is fairly comparable but the K-7 (APS-C) and WG-1 GPS (1/2.3") posses totally different sensor measurements.

The K-7 was revealed 22 months earlier than the WG-1 GPS making them a generation apart from one another. Both the cameras feature different body design with the Pentax K-7 being a Mid-size SLR camera and the Pentax WG-1 GPS being a Compact camera.

Before diving right into a thorough comparison, here is a short synopsis of how the K-7 grades vs the WG-1 GPS in the way of portability, imaging, features and an overall grade.

Here is a sample of the gallery pictures for Pentax K-7 and Pentax Optio WG-1 GPS. The full galleries are viewable at Pentax K-7 Gallery and Pentax WG-1 GPS Gallery.

When you are intending to lug around your camera regularly, you need to factor in its weight and dimensions. The Pentax K-7 has physical dimensions of 131mm x 97mm x 73mm (5.2" x 3.8" x 2.9") with a weight of 750 grams (1.65 lbs) while the Pentax WG-1 GPS has dimensions of 116mm x 59mm x 29mm (4.6" x 2.3" x 1.1") having a weight of 167 grams (0.37 lbs).

Bear in mind, the weight of an Interchangeable Lens Camera will vary depending on the lens you select at that moment. Here is a front view proportions comparison of the K-7 versus the WG-1 GPS.

Taking into consideration dimensions and weight, the portability grade of the K-7 and WG-1 GPS is 60 and 93 respectively.

Normally, it's difficult to visualise the contrast in sensor measurements merely by seeing specifications. The graphic here might give you a far better sense of the sensor dimensions in the K-7 and WG-1 GPS.

To sum up, both the cameras come with different megapixel count and different sensor measurements. The K-7 using its larger sensor will make getting shallow DOF less difficult and the Pentax K-7 will produce greater detail because of its extra 1 Megapixels. Greater resolution can also allow you to crop photos a good deal more aggressively. The older K-7 will be behind with regard to sensor innovation.
