Pentax X70 vs Ricoh GR III

Below, we are evaluating the Pentax X70 versus Ricoh GR III, one being a Small Sensor Superzoom and the other is a Large Sensor Compact by manufacturers Pentax and Ricoh. There exists a crucial gap among the sensor resolutions of the X70 (12MP) and GR III (24MP) and the X70 (1/2.3") and GR III (APS-C) come with different sensor dimensions.

The X70 was unveiled 10 years prior to the GR III and that is a fairly serious gap as far as camera technology is concerned. Each of these cameras come with different body type with the Pentax X70 being a SLR-like (bridge) camera and the Ricoh GR III being a Large Sensor Compact camera.

Before going through a detailed comparison, below is a short view of how the X70 scores against the GR III with respect to portability, imaging, features and an overall rating.

Here is a sample of the gallery pictures for Pentax X70 and Ricoh GR III. The full galleries are provided at Pentax X70 Gallery and Ricoh GR III Gallery.

When you are intending to carry your camera, you're going to have to consider its weight and volume.

Take into account, the weight of an Interchangeable Lens Camera will differ dependant on the lens you have attached during that time. The following is the front view size comparison of the X70 versus the GR III.

Factoring in dimensions and weight, the portability grade of the X70 and GR III is 71 and 90 respectively.

More often than not, its tough to picture the gap in sensor sizing just by seeing specs. The visual below will provide you a far better sense of the sensor measurements in the X70 and GR III.

All in all, both the cameras have got different resolutions and different sensor sizing. The X70 with its smaller sensor is going to make achieving shallow DOF trickier and the Ricoh GR III will provide greater detail having an extra 12MP. Greater resolution will allow you to crop pics much more aggressively. The older X70 will be behind when it comes to sensor technology.
