Olympus TG-310 vs Sony RX100

Here is a in-depth analysis of the Olympus TG-310 and Sony RX100, former being a Waterproof while the other is a Large Sensor Compact by rivals Olympus and Sony. There is a large difference among the image resolutions of the TG-310 (14MP) and RX100 (20MP) and the TG-310 (1/2.3") and RX100 (1") offer totally different sensor sizes.

The TG-310 was introduced 20 months prior to the RX100 making them a generation apart from each other. Each of these cameras have different body design with the Olympus TG-310 being a Compact camera and the Sony RX100 being a Large Sensor Compact camera.

Before we go right into a more detailed comparison, here is a quick summation of how the TG-310 scores versus the RX100 when it comes to portability, imaging, features and an overall rating.

Here is a sample of the gallery pictures for Olympus TG-310 & Sony Cyber-shot DSC-RX100. The whole galleries are viewable at Olympus TG-310 Gallery & Sony RX100 Gallery.

For anyone who is planning to carry your camera often, you're going to have to factor in its weight and proportions.

Remember that, the weight of an ILC will change based on the lens you use at that moment. Below is a front view physical size comparison of the TG-310 against the RX100.

Looking at size and weight, the portability grade of the TG-310 and RX100 is 94 and 91 respectively.

Often, it is very hard to visualise the contrast in sensor sizing merely by researching a spec sheet. The photograph underneath should give you a better sense of the sensor sizes in the TG-310 and RX100.

As you can see, both the cameras provide different megapixel count and different sensor sizing. The TG-310 with its smaller sensor will make achieving shallow DOF trickier and the Sony RX100 will render greater detail using its extra 6 Megapixels. Greater resolution will also help you crop pics more aggressively. The older TG-310 will be disadvantaged with regard to sensor tech.
