Panasonic GH1 vs Pentax K-01

Let's look a little more closely at the Panasonic GH1 and Pentax K-01, former being a Advanced Mirrorless while the other is a Entry-Level Mirrorless by manufacturers Panasonic and Pentax. There exists a large gap between the image resolutions of the GH1 (12MP) and K-01 (16MP) and the GH1 (Four Thirds) and K-01 (APS-C) posses different sensor size.

The GH1 was brought out 3 years before the K-01 and that is quite a serious difference as far as technology is concerned. Both of the cameras have the same body design (SLR-style mirrorless).

Before going into a in depth comparison, here is a short view of how the GH1 scores against the K-01 in the way of portability, imaging, features and an overall grade.

The following is a sample of the gallery pics for Panasonic Lumix DMC-GH1 & Pentax K-01. The entire galleries are viewable at Panasonic GH1 Gallery & Pentax K-01 Gallery.

When you are intending to lug around your camera regularly, you'll have to think about its weight and measurements. The Panasonic GH1 comes with outer measurements of 124mm x 90mm x 45mm (4.9" x 3.5" x 1.8") with a weight of 385 grams (0.85 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).

Do not forget, the weight of an ILC will vary dependant on the lens you are utilizing at that moment. Below is a front view physical size comparison of the GH1 and the K-01.

Taking into account dimensions and weight, the portability rating of the GH1 and K-01 is 81 and 76 respectively.

More often than not, it is tough to visualize the difference between sensor measurements purely by reading technical specs. The graphic underneath might offer you a much better sense of the sensor sizing in the GH1 and K-01.

As you can tell, both of those cameras have different megapixel count and different sensor measurements. The GH1 because of its tinier sensor is going to make getting shallow DOF harder and the Pentax K-01 will deliver more detail having its extra 4MP. Greater resolution will also help you crop photos a bit more aggressively. The older GH1 is going to be disadvantaged when it comes to sensor tech.
