Olympus E-1 vs Pentax WG-1 GPS

Lets look more in depth at the Olympus E-1 and Pentax WG-1 GPS, one being a Pro DSLR and the latter is a Waterproof by companies Olympus and Pentax. There exists a sizeable gap among the sensor resolutions of the E-1 (5MP) and WG-1 GPS (14MP) and the E-1 (Four Thirds) and WG-1 GPS (1/2.3") provide different sensor dimensions.

Taking into account dimensions and weight, the portability grade of the E-1 and WG-1 GPS is 59 and 93 respectively.

Sometimes, it is very difficult to visualize the contrast in sensor measurements simply by seeing a spec sheet. The visual underneath should give you a much better sense of the sensor dimensions in the E-1 and WG-1 GPS.

Clearly, both of the cameras have different megapixel count and different sensor measurements. The E-1 featuring a bigger sensor is going to make shooting shallower DOF less difficult and the Pentax WG-1 GPS will provide greater detail having its extra 9MP. Higher resolution will allow you to crop shots a bit more aggressively. The older E-1 will be disadvantaged with regard to sensor innovation.
