Pentax K20D vs Pentax WG-2

Here, we will be matching up the Pentax K20D versus Pentax WG-2, one being a Advanced DSLR and the latter is a Waterproof and both are sold by Pentax. The sensor resolution of the K20D (15MP) and the WG-2 (16MP) is relatively close but the K20D (APS-C) and WG-2 (1/2.3") offer totally different sensor sizes.

The K20D was unveiled 4 years earlier than the WG-2 and that is a fairly significant gap as far as camera technology is concerned. The two cameras feature different body design with the Pentax K20D being a Mid-size SLR camera and the Pentax WG-2 being a Compact camera.

Before delving straight to a thorough comparison, here is a quick summation of how the K20D grades versus the WG-2 with respect to portability, imaging, features and an overall grade.

Below is a preview of the gallery photos for Pentax K20D and Pentax Optio WG-2. The full galleries are available at Pentax K20D Gallery and Pentax WG-2 Gallery.

If you're looking to lug around your camera regularly, you have to take into account its weight and measurements. The Pentax K20D offers outer dimensions of 142mm x 101mm x 70mm (5.6" x 4.0" x 2.8") and a weight of 800 grams (1.76 lbs) whilst the Pentax WG-2 has proportions of 122mm x 61mm x 30mm (4.8" x 2.4" x 1.2") with a weight of 192 grams (0.42 lbs).

Remember, the weight of an Interchangeable Lens Camera will change based on the lens you have during that time. Below is a front view physical size comparison of the K20D compared to the WG-2.

Using dimensions and weight, the portability rating of the K20D and WG-2 is 59 and 91 respectively.

Sometimes, it can be difficult to visualise the contrast in sensor measurements purely by researching specs. The photograph below might give you a better sense of the sensor sizes in the K20D and WG-2.

As you can plainly see, both of those cameras feature different megapixels and different sensor measurements. The K20D having a bigger sensor will make shooting shallow DOF simpler and the Pentax WG-2 will result in more detail having an extra 1MP. Higher resolution can also let you crop shots way more aggressively. The older K20D will be behind when it comes to sensor tech.
