The WG-3 was unveiled 3 years after the A450 which is a fairly sizable difference as far as camera tech is concerned. Both of the cameras offer different body type with the Pentax WG-3 being a Compact camera and the Sony A450 being a Compact SLR camera.

Before we go in to a detailed comparison, below is a simple highlight of how the WG-3 grades against the A450 with regards to portability, imaging, features and an overall mark.

Keep in mind, the weight of an ILC will differ depending on the lens you are working with at that time. Below is the front view size comparison of the WG-3 compared to the A450.

Factoring in size and weight, the portability score of the WG-3 and A450 is 90 and 65 respectively.

Often, it's tough to picture the contrast in sensor dimensions purely by going through a spec sheet. The image underneath will offer you a better sense of the sensor measurements in the WG-3 and A450.

Clearly, both of these cameras offer different megapixels and different sensor dimensions. The WG-3 using its smaller sensor is going to make achieving shallower depth of field more challenging and the Pentax WG-3 will produce greater detail having an extra 2 Megapixels. Higher resolution will also let you crop photographs a little more aggressively. The fresher WG-3 should have an edge with regard to sensor innovation.
