The WG-3 was unveiled 2 years later than the SD1 and that is a fairly sizable gap as far as camera tech is concerned. The two cameras come with different body type with the Pentax WG-3 being a Compact camera and the Sigma SD1 being a Mid-size SLR camera.

Before going straight into a step-by-step comparison, below is a short overview of how the WG-3 grades versus the SD1 in relation to portability, imaging, features and an overall grade.

Here is a preview of the gallery images for Pentax WG-3 and Sigma SD1. The full galleries are viewable at Pentax WG-3 Gallery and Sigma SD1 Gallery.

In many cases, it can be difficult to imagine the contrast in sensor measurements only by researching specs. The photograph underneath may give you a far better sense of the sensor dimensions in the WG-3 and SD1.

As you can plainly see, the 2 cameras have got different megapixel count and different sensor measurements. The WG-3 having a smaller sensor is going to make achieving shallower depth of field more challenging and the Pentax WG-3 will render more detail having an extra 1 Megapixels. Higher resolution will also allow you to crop shots much more aggressively. The younger WG-3 provides an advantage in sensor technology.
