Panasonic GH5S vs Pentax RZ18

In this write-up, we are analyzing the Panasonic GH5S versus Pentax RZ18, former being a Pro Mirrorless while the other is a Small Sensor Superzoom by manufacturers Panasonic and Pentax. There exists a sizable gap between the image resolutions of the GH5S (10MP) and RZ18 (16MP) and the GH5S (Four Thirds) and RZ18 (1/2.3") possess totally different sensor size.

The GH5S was released 6 years later than the RZ18 and that is quite a significant difference as far as technology is concerned. Both of these cameras offer different body type with the Panasonic GH5S being a SLR-style mirrorless camera and the Pentax RZ18 being a Compact camera.

Before going through a in-depth comparison, below is a short synopsis of how the GH5S grades vs the RZ18 in terms of portability, imaging, features and an overall grade.

Here is a sample of the gallery pictures for Panasonic Lumix DC-GH5S & Pentax Optio RZ18. The complete galleries are viewable at Panasonic GH5S Gallery & Pentax RZ18 Gallery.

For anyone who is going to lug around your camera frequently, you should take into account its weight and proportions.

More often than not, it can be tough to envision the contrast between sensor measurements only by looking at a spec sheet. The photograph underneath will give you a far better sense of the sensor sizes in the GH5S and RZ18.

As you can see, both of those cameras offer different megapixel count and different sensor measurements. The GH5S due to its larger sensor will make shooting shallower DOF simpler and the Pentax RZ18 will give you greater detail as a result of its extra 6 Megapixels. Greater resolution will also make it easier to crop photos a little more aggressively. The younger GH5S is going to have an advantage when it comes to sensor innovation.
