Pentax WG-1 GPS vs Sony A900

On this page, we will be reviewing the Pentax WG-1 GPS versus Sony A900, one is a Waterproof and the latter is a Advanced DSLR by brands Pentax and Sony. There exists a crucial gap between the image resolutions of the WG-1 GPS (14MP) and A900 (25MP) and the WG-1 GPS (1/2.3") and A900 (Full frame) provide totally different sensor sizing.

The WG-1 GPS was unveiled 2 years after the A900 which is quite a serious gap as far as technology is concerned. The two cameras have different body design with the Pentax WG-1 GPS being a Compact camera and the Sony A900 being a Mid-size SLR camera.

Before we go straight to a more detailed comparison, here is a concise summation of how the WG-1 GPS grades versus the A900 for portability, imaging, features and an overall score.

Following is a preview of the gallery images for Pentax Optio WG-1 GPS and Sony Alpha DSLR-A900. The full galleries are viewable at Pentax WG-1 GPS Gallery and Sony A900 Gallery.

For those who are aiming to carry around your camera often, you will need to consider its weight and proportions. The Pentax WG-1 GPS features outside dimensions of 116mm x 59mm x 29mm (4.6" x 2.3" x 1.1") and a weight of 167 grams (0.37 lbs) whilst the Sony A900 has measurements of 156mm x 117mm x 82mm (6.1" x 4.6" x 3.2") along with a weight of 895 grams (1.97 lbs).

Remember that, the weight of an Interchangeable Lens Camera will differ depending on the lens you are utilising at the time. Here is a front view size comparison of the WG-1 GPS against the A900.

Looking at dimensions and weight, the portability grade of the WG-1 GPS and A900 is 93 and 54 respectively.

More often than not, its difficult to see the contrast between sensor sizes merely by reading through specifications. The picture underneath might give you a stronger sense of the sensor sizes in the WG-1 GPS and A900.

Plainly, both of these cameras provide different megapixels and different sensor sizes. The WG-1 GPS using its tinier sensor will make achieving shallower DOF more challenging and the Sony A900 will resolve extra detail having an extra 11 Megapixels. Higher resolution will make it easier to crop pictures more aggressively. The fresher WG-1 GPS is going to have an advantage in sensor innovation.
