Olympus TG-310 vs Sigma DP1s

Its time to look much closer at the Olympus TG-310 versus Sigma DP1s, one being a Waterproof and the latter is a Large Sensor Compact by brands Olympus and Sigma. There exists a huge gap among the resolutions of the TG-310 (14MP) and DP1s (5MP) and the TG-310 (1/2.3") and DP1s (APS-C) feature totally different sensor size.

The TG-310 was introduced 16 months later than the DP1s which makes the cameras a generation apart from one another. Both cameras come with different body type with the Olympus TG-310 being a Compact camera and the Sigma DP1s being a Large Sensor Compact camera.

Before we go through a step-by-step comparison, below is a brief summary of how the TG-310 matches up vs the DP1s with regards to portability, imaging, features and an overall rating.

Here is a preview of the gallery photos for Olympus TG-310 and Sigma DP1s. The whole galleries are available at Olympus TG-310 Gallery and Sigma DP1s Gallery.

For those who are planning to carry your camera often, you'll need to factor in its weight and size. The Olympus TG-310 has outer dimensions of 96mm x 63mm x 23mm (3.8" x 2.5" x 0.9") along with a weight of 155 grams (0.34 lbs) whilst the Sigma DP1s has specifications of 109mm x 60mm x 31mm (4.3" x 2.4" x 1.2") with a weight of 270 grams (0.60 lbs).

Keep in mind, the weight of an Interchangeable Lens Camera will change based on the lens you have during that time. Below is the front view proportions comparison of the TG-310 vs the DP1s.

Factoring in dimensions and weight, the portability grade of the TG-310 and DP1s is 94 and 90 respectively.

Quite often, it can be hard to see the gap in sensor sizing only by seeing specifications. The visual here may offer you a much better sense of the sensor dimensions in the TG-310 and DP1s.

Plainly, both of these cameras have got different resolutions and different sensor sizing. The TG-310 using its smaller sensor will make getting shallow depth of field more difficult and the Olympus TG-310 will show greater detail using its extra 9MP. Higher resolution will allow you to crop shots much more aggressively. The newer TG-310 will have an advantage in sensor tech.
