Panasonic G3 vs Panasonic GH5

Let's take a deeper look at the Panasonic G3 vs Panasonic GH5, one being a Entry-Level Mirrorless and the latter is a Pro Mirrorless and both are produced by Panasonic. The sensor resolution of the G3 (16MP) and the GH5 (20MP) is relatively well matched and both cameras boast the same sensor size (Four Thirds).

The G3 was unveiled 6 years earlier than the GH5 and that is quite a serious gap as far as technology is concerned. The two cameras have the same body design (SLR-style mirrorless).

Before getting straight to a in-depth comparison, here is a short introduction of how the G3 grades vs the GH5 with regards to portability, imaging, features and an overall grade.

Here is a preview of the gallery photos for Panasonic Lumix DMC-G3 and Panasonic Lumix DMC-GH5. The full galleries are available at Panasonic G3 Gallery and Panasonic GH5 Gallery.

For those who are going to lug around your camera regularly, you will need to factor its weight and measurements. The Panasonic G3 comes with external measurements of 115mm x 84mm x 47mm (4.5" x 3.3" x 1.9") accompanied by a weight of 336 grams (0.74 lbs) whilst the Panasonic GH5 has proportions of 139mm x 98mm x 87mm (5.5" x 3.9" x 3.4") and a weight of 725 grams (1.60 lbs).

Remember that, the weight of an Interchangeable Lens Camera will vary based on the lens you use at that time. Here is a front view dimension comparison of the G3 compared to the GH5.

Taking into account dimensions and weight, the portability score of the G3 and GH5 is 83 and 59 respectively.

Normally, it can be tough to envision the gap between sensor measurements only by reading through technical specs. The graphic here will help provide you a far better sense of the sensor sizing in the G3 and GH5.

As you have seen, the 2 cameras provide the same sensor dimensions albeit not the same resolution. You should count on the Panasonic GH5 to give more detail having an extra 4MP. Higher resolution will also enable you to crop shots more aggressively. The older G3 is going to be disadvantaged in sensor technology.
