The TG-320 was introduced 2 years later than the DP2 and that is a fairly significant gap as far as camera technology is concerned. Both of the cameras have different body design with the Olympus TG-320 being a Compact camera and the Sigma DP2 being a Large Sensor Compact camera.

Before going straight to a in-depth comparison, here is a quick highlight of how the TG-320 scores against the DP2 with regard to portability, imaging, features and an overall rating.

Here is a sample of the gallery pics for Olympus TG-320 and Sigma DP2. The whole galleries are available at Olympus TG-320 Gallery and Sigma DP2 Gallery.

If you are looking to carry your camera often, you should take into account its weight and proportions.

Do not forget, the weight of an Interchangeable Lens Camera will change dependant on the lens you have chosen at the time. Following is a front view measurement comparison of the TG-320 versus the DP2.

Using dimensions and weight, the portability rating of the TG-320 and DP2 is 94 and 86 respectively.

Typically, it's hard to visualise the contrast in sensor sizing only by researching a spec sheet. The photograph here will help give you a clearer sense of the sensor measurements in the TG-320 and DP2.

Clearly, each of these cameras provide different megapixels and different sensor sizing. The TG-320 using its smaller sensor will make shooting shallower depth of field trickier and the Olympus TG-320 will provide you with extra detail using its extra 9 Megapixels. Greater resolution will enable you to crop images more aggressively. The fresher TG-320 will have a benefit in sensor innovation.
