The G10 was revealed 2 years later than the K20D and that is quite a large difference as far as tech is concerned. Both cameras feature different body design with the Panasonic G10 being a SLR-style mirrorless camera and the Pentax K20D being a Mid-size SLR camera.

Before delving straight to a detailed comparison, here is a concise highlight of how the G10 scores against the K20D in relation to portability, imaging, features and an overall grade.

Here is a sample of the gallery pics for Panasonic Lumix DMC-G10 & Pentax K20D. The full galleries are viewable at Panasonic G10 Gallery & Pentax K20D Gallery.

For those who are looking to lug around your camera regularly, you're going to have to think about its weight and dimensions.

Often, it is very difficult to visualize the difference between sensor measurements purely by reading a spec sheet. The visual below might provide you a clearer sense of the sensor sizing in the G10 and K20D.

As you can see, the two cameras come with different megapixel count and different sensor measurements. The G10 using its tinier sensor is going to make getting shallower depth of field tougher and the Pentax K20D will deliver more detail because of its extra 3MP. Greater resolution will make it easier to crop images a good deal more aggressively. The younger G10 provides an advantage in sensor innovation.
