Panasonic G100 vs Sony RX100 III

Let's take a closer look at the Panasonic G100 and Sony RX100 III, one being a Entry-Level Mirrorless and the latter is a Large Sensor Compact by manufacturers Panasonic and Sony. The sensor resolution of the G100 (20MP) and the RX100 III (20MP) is pretty close but the G100 (Four Thirds) and RX100 III (1") feature totally different sensor size.

The G100 was launched 6 years later than the RX100 III and that is a fairly big gap as far as camera technology is concerned. Each of these cameras offer different body type with the Panasonic G100 being a SLR-style mirrorless camera and the Sony RX100 III being a Large Sensor Compact camera.

Before getting through a in-depth comparison, below is a concise highlight of how the G100 grades against the RX100 III with regards to portability, imaging, features and an overall rating.

More often than not, its tough to see the contrast in sensor sizing simply by researching a spec sheet. The graphic below will give you a much better sense of the sensor dimensions in the G100 and RX100 III.

Clearly, both of the cameras offer the same exact megapixel count albeit not the same sensor sizing. The G100 provides the bigger sensor which should make getting shallow depth of field less difficult. The younger G100 is going to have an advantage when it comes to sensor technology.
