Canon SX120 IS vs Ricoh GR III

Here, we are comparing the Canon SX120 IS and Ricoh GR III, one being a Small Sensor Compact and the other is a Large Sensor Compact by manufacturers Canon and Ricoh. There exists a huge gap among the resolutions of the SX120 IS (10MP) and GR III (24MP) and the SX120 IS (1/2.5") and GR III (APS-C) have different sensor sizing.

The SX120 IS was introduced 10 years before the GR III and that is a fairly significant gap as far as camera technology is concerned. Each of these cameras feature different body design with the Canon SX120 IS being a Compact camera and the Ricoh GR III being a Large Sensor Compact camera.

Before getting right into a comprehensive comparison, here is a short summation of how the SX120 IS matches up versus the GR III in relation to portability, imaging, features and an overall grade.

If you are going to lug around your camera regularly, you are going to need to take into account its weight and measurements. The Canon SX120 IS provides outer dimensions of 111mm x 71mm x 45mm (4.4" x 2.8" x 1.8") having a weight of 285 grams (0.63 lbs) whilst the Ricoh GR III has proportions of 109mm x 62mm x 33mm (4.3" x 2.4" x 1.3") with a weight of 257 grams (0.57 lbs).

Take into account, the weight of an Interchangeable Lens Camera will vary depending on the lens you have at that time. Here is a front view size comparison of the SX120 IS compared to the GR III.

Considering dimensions and weight, the portability score of the SX120 IS and GR III is 87 and 90 respectively.

More often than not, it's tough to picture the contrast in sensor measurements only by going through technical specs. The graphic underneath might offer you a much better sense of the sensor dimensions in the SX120 IS and GR III.

As you have seen, both of the cameras feature different megapixels and different sensor measurements. The SX120 IS having a smaller sensor is going to make getting shallow DOF more difficult and the Ricoh GR III will show more detail using its extra 14 Megapixels. Greater resolution will also enable you to crop images way more aggressively. The older SX120 IS will be disadvantaged in sensor technology.
