The WG-3 GPS was introduced 3 years after the NEX-3 which is quite a large gap as far as technology is concerned. Each of the cameras feature different body design with the Pentax WG-3 GPS being a Compact camera and the Sony NEX-3 being a Rangefinder-style mirrorless camera.

Before going right into a thorough comparison, here is a brief synopsis of how the WG-3 GPS scores vs the NEX-3 when it comes to portability, imaging, features and an overall score.

Typically, it can be difficult to visualise the contrast between sensor sizes merely by reading through technical specs. The image underneath will help give you a far better sense of the sensor sizes in the WG-3 GPS and NEX-3.

As you can tell, both of the cameras come with different megapixel count and different sensor sizes. The WG-3 GPS with its tinier sensor will make shooting shallow DOF more difficult and the Pentax WG-3 GPS will give you extra detail using its extra 2MP. Greater resolution will also let you crop pics a good deal more aggressively. The more recent WG-3 GPS will have a benefit with regard to sensor innovation.
