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.

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.
