Panasonic G3 vs Pentax K-01

In this write-up, we are looking at the Panasonic G3 and Pentax K-01, both Entry-Level Mirrorless digital cameras by brands Panasonic and Pentax. The image resolution of the G3 (16MP) and the K-01 (16MP) is fairly well matched but the G3 (Four Thirds) and K-01 (APS-C) use totally different sensor measurements.

The G3 was introduced 10 months earlier than the K-01 so they are both of a similar generation. Both the cameras offer the identical body type (SLR-style mirrorless).

Before delving through a full comparison, below is a concise highlight of how the G3 matches up vs the K-01 with regards to portability, imaging, features and an overall grade.

Following is a sample of the gallery pictures for Panasonic Lumix DMC-G3 and Pentax K-01. The whole galleries are provided at Panasonic G3 Gallery and Pentax K-01 Gallery.

When you are looking to lug around your camera, you should think about its weight and measurements. The Panasonic G3 features physical dimensions 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 Pentax K-01 has proportions of 122mm x 79mm x 58mm (4.8" x 3.1" x 2.3") with a weight of 561 grams (1.24 lbs).

Keep in mind, the weight of an Interchangeable Lens Camera will change dependant on the lens you are utilising at that time. Underneath is the front view dimensions comparison of the G3 and the K-01.

Looking at dimensions and weight, the portability rating of the G3 and K-01 is 83 and 76 respectively.

Typically, it is very hard to visualise the difference between sensor measurements merely by looking at technical specs. The photograph below should give you a greater sense of the sensor dimensions in the G3 and K-01.

As you have seen, both of these cameras enjoy the same exact megapixels but not the same sensor measurements. The G3 comes with the tinier sensor which will make achieving shallow DOF harder. The older G3 is going to be behind with regard to sensor tech.
