Panasonic G9 vs Pentax K-3 II

Let's look closer at the Panasonic G9 and Pentax K-3 II, former being a Pro Mirrorless while the other is a Advanced DSLR by companies Panasonic and Pentax. The resolution of the G9 (20MP) and the K-3 II (24MP) is fairly well matched but the G9 (Four Thirds) and K-3 II (APS-C) come with totally different sensor size.

The G9 was announced 2 years later than the K-3 II and that is quite a significant difference as far as tech is concerned. Both the cameras come with different body type with the Panasonic G9 being a SLR-style mirrorless camera and the Pentax K-3 II being a Mid-size SLR camera.

Before delving through a complete comparison, below is a short summation of how the G9 scores against the K-3 II with regard to portability, imaging, features and an overall rating.

Following is a sample of the gallery pictures for Panasonic Lumix DC-G9 & Pentax K-3 II. The whole galleries are available at Panasonic G9 Gallery & Pentax K-3 II Gallery.

When you are going to carry your camera often, you need to take into account its weight and measurements.

In many cases, it is hard to visualise the difference between sensor sizing just by checking a spec sheet. The graphic below might offer you a much better sense of the sensor measurements in the G9 and K-3 II.

Clearly, each of these cameras posses different resolutions and different sensor sizing. The G9 using its tinier sensor will make getting shallower DOF more challenging and the Pentax K-3 II will give more detail with its extra 4MP. Greater resolution will make it easier to crop images somewhat more aggressively. The more recent G9 will have an advantage in sensor tech.
