The GH3 was unveiled 5 years later than the K10D and that is a fairly large difference as far as camera technology is concerned. Each of the cameras come with different body type with the Panasonic GH3 being a SLR-style mirrorless camera and the Pentax K10D being a Mid-size SLR camera.

Before going straight into a more detailed comparison, below is a short summary of how the GH3 matches up against the K10D in relation to portability, imaging, features and an overall grade.

Following is a sample of the gallery pics for Panasonic Lumix DMC-GH3 & Pentax K10D. The full galleries are viewable at Panasonic GH3 Gallery & Pentax K10D Gallery.

More often than not, it's hard to envision the difference in sensor measurements simply by going through technical specs. The graphic here will give you a much better sense of the sensor dimensions in the GH3 and K10D.

As you can tell, each of these cameras have got different megapixel count and different sensor measurements. The GH3 having a smaller sensor will make shooting shallow depth of field harder and the Panasonic GH3 will show greater detail having an extra 6 Megapixels. Greater resolution will help you crop images much more aggressively. The more modern GH3 will have an advantage with regard to sensor technology.
