Pentax WG-3 vs Sigma DP1

Lets take a deeper look at the Pentax WG-3 vs Sigma DP1, former being a Waterproof while the other is a Large Sensor Compact by companies Pentax and Sigma. There exists a noticeable gap among the sensor resolutions of the WG-3 (16MP) and DP1 (5MP) and the WG-3 (1/2.3") and DP1 (APS-C) use totally different sensor sizes.

The WG-3 was unveiled 5 years later than the DP1 and that is a fairly sizable difference as far as camera technology is concerned. The two cameras come with different body type with the Pentax WG-3 being a Compact camera and the Sigma DP1 being a Large Sensor Compact camera.

Before we go in to a step-by-step comparison, below is a short overview of how the WG-3 matches up against the DP1 in regards to portability, imaging, features and an overall rating.

Following is a sample of the gallery pictures for Pentax WG-3 & Sigma DP1. The full galleries are viewable at Pentax WG-3 Gallery & Sigma DP1 Gallery.

For those who are looking to carry your camera frequently, you are going to need to factor in its weight and proportions.

Take into account, the weight of an ILC will change dependant on the lens you choose during that time. Below is the front view sizing comparison of the WG-3 vs the DP1.

Using dimensions and weight, the portability grade of the WG-3 and DP1 is 90 and 87 respectively.

Sometimes, it is tough to envision the difference in sensor sizing purely by researching a spec sheet. The graphic below might provide you a stronger sense of the sensor sizing in the WG-3 and DP1.

Clearly, both of these cameras posses different megapixel count and different sensor sizing. The WG-3 using its smaller sensor will make shooting shallow depth of field more difficult and the Pentax WG-3 will provide you with more detail having an extra 11MP. Greater resolution will also let you crop images somewhat more aggressively. The newer WG-3 will have an edge in sensor tech.
