Panasonic GH5S vs Pentax K-01

Let's look a bit more in depth at the Panasonic GH5S and Pentax K-01, one being a Pro Mirrorless and the latter is a Entry-Level Mirrorless by manufacturers Panasonic and Pentax. There is a crucial difference among the sensor resolutions of the GH5S (10MP) and K-01 (16MP) and the GH5S (Four Thirds) and K-01 (APS-C) use totally different sensor size.

The GH5S was announced 5 years later than the K-01 and that is a fairly serious gap as far as camera tech is concerned. The two cameras offer the identical body type (SLR-style mirrorless).

Before delving in to a thorough comparison, below is a simple overview of how the GH5S scores vs the K-01 with regard to portability, imaging, features and an overall grade.

Below is a preview of the gallery photos for Panasonic Lumix DC-GH5S and Pentax K-01. The whole galleries are viewable at Panasonic GH5S Gallery and Pentax K-01 Gallery.

If you're intending to lug around your camera, you'll need to consider its weight and volume. The Panasonic GH5S comes with exterior dimensions of 139mm x 98mm x 87mm (5.5" x 3.9" x 3.4") and a weight of 660 grams (1.46 lbs) and the Pentax K-01 has sizing of 122mm x 79mm x 58mm (4.8" x 3.1" x 2.3") and a weight of 561 grams (1.24 lbs).

Do not forget, the weight of an Interchangeable Lens Camera will vary depending on the lens you use at the time. Here is the front view dimensions comparison of the GH5S versus the K-01.

Taking into consideration size and weight, the portability score of the GH5S and K-01 is 62 and 76 respectively.

In many cases, it can be difficult to visualise the gap in sensor measurements only by looking through technical specs. The visual below may offer you a more clear sense of the sensor sizes in the GH5S and K-01.

As you can tell, each of these cameras offer different megapixel count and different sensor measurements. The GH5S using its smaller sensor will make achieving shallower DOF more challenging and the Pentax K-01 will result in greater detail with its extra 6 Megapixels. Higher resolution can also help you crop shots a little more aggressively. The newer GH5S will have a benefit when it comes to sensor tech.
