Pentax WG-3 GPS vs Sony NEX-3

Following is a extended analysis of the Pentax WG-3 GPS and Sony NEX-3, one is a Waterproof and the other is a Entry-Level Mirrorless by rivals Pentax and Sony. The image resolution of the WG-3 GPS (16MP) and the NEX-3 (14MP) is fairly well matched but the WG-3 GPS (1/2.3") and NEX-3 (APS-C) offer totally different sensor size.

Photography Glossary

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.

Following is a sample of the gallery pictures for Pentax WG-3 GPS and Sony Alpha NEX-3. The whole galleries are provided at Pentax WG-3 GPS Gallery and Sony NEX-3 Gallery.

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.
