Pentax K20D vs Pentax WG-1

Its time to examine more in depth at the Pentax K20D and Pentax WG-1, one is a Advanced DSLR and the latter is a Waterproof and they are both designed by Pentax. The sensor resolution of the K20D (15MP) and the WG-1 (14MP) is relatively close but the K20D (APS-C) and WG-1 (1/2.3") use different sensor sizing.

The K20D was manufactured 3 years prior to the WG-1 which is a fairly significant gap as far as camera tech is concerned. Both of these cameras come with different body type with the Pentax K20D being a Mid-size SLR camera and the Pentax WG-1 being a Compact camera.

Before getting through a complete comparison, below is a simple summary of how the K20D scores versus the WG-1 in terms of portability, imaging, features and an overall score.

The following is a preview of the gallery photos for Pentax K20D and Pentax Optio WG-1. The entire galleries are provided at Pentax K20D Gallery and Pentax WG-1 Gallery.

If you are planning to carry around your camera often, you're going to have to consider its weight and size. The Pentax K20D has outer measurements of 142mm x 101mm x 70mm (5.6" x 4.0" x 2.8") with a weight of 800 grams (1.76 lbs) whilst the Pentax WG-1 has specifications of 114mm x 58mm x 28mm (4.5" x 2.3" x 1.1") along with a weight of 157 grams (0.35 lbs).

Remember, the weight of an Interchangeable Lens Camera will differ depending on the lens you choose at that time. Following is the front view measurement comparison of the K20D compared to the WG-1.

Looking at size and weight, the portability score of the K20D and WG-1 is 59 and 93 respectively.

Often, it is hard to imagine the difference in sensor sizes purely by researching specs. The picture here might offer you a clearer sense of the sensor measurements in the K20D and WG-1.

As you can plainly see, each of these cameras have got different resolutions and different sensor sizes. The K20D because of its bigger sensor is going to make shooting shallow depth of field simpler and the Pentax K20D will render more detail due to its extra 1 Megapixels. Higher resolution will make it easier to crop shots much more aggressively. The more aged K20D will be behind in sensor innovation.
