Panasonic G1 vs Pentax K10D

Let's look a little more in depth at the Panasonic G1 vs Pentax K10D, one being a Entry-Level Mirrorless and the other is a Advanced DSLR by manufacturers Panasonic and Pentax. The sensor resolution of the G1 (12MP) and the K10D (10MP) is fairly close but the G1 (Four Thirds) and K10D (APS-C) have different sensor sizes.

The G1 was released 2 years later than the K10D and that is a fairly big gap as far as camera technology is concerned. Both of the cameras feature different body design with the Panasonic G1 being a SLR-style mirrorless camera and the Pentax K10D being a Mid-size SLR camera.

Before we go right into a full comparison, here is a concise synopsis of how the G1 grades versus the K10D with regard to portability, imaging, features and an overall grade.

Below is a sample of the gallery pictures for Panasonic Lumix DMC-G1 and Pentax K10D. The complete galleries are viewable at Panasonic G1 Gallery and Pentax K10D Gallery.

If you are going to lug around your camera, you will want to factor its weight and dimensions.

Do not forget, the weight of an Interchangeable Lens Camera will vary depending on the lens you use at the time. The following is a front view measurement comparison of the G1 against the K10D.

Considering dimensions and weight, the portability score of the G1 and K10D is 82 and 59 respectively.

Typically, it is difficult to picture the difference in sensor measurements purely by looking through technical specs. The photograph here may offer you a clearer sense of the sensor sizing in the G1 and K10D.

As you have seen, both of those cameras feature different megapixels and different sensor measurements. The G1 featuring a smaller sensor is going to make shooting shallow DOF tougher and the Panasonic G1 will provide you with more detail as a result of its extra 2MP. Greater resolution will also enable you to crop photos way more aggressively. The more recent G1 should have an edge when it comes to sensor innovation.
