The ZS20 was released 2 years later than the K-7 and that is quite a sizable gap as far as technology is concerned. Both of the cameras offer different body type with the Panasonic ZS20 being a Compact camera and the Pentax K-7 being a Mid-size SLR camera.

Before getting straight into a full comparison, below is a brief introduction of how the ZS20 matches up vs the K-7 in the way of portability, imaging, features and an overall grade.

Below is a sample of the gallery pictures for Panasonic Lumix DMC-ZS20 and Pentax K-7. The complete galleries are available at Panasonic ZS20 Gallery and Pentax K-7 Gallery.

Quite often, its difficult to visualize the contrast between sensor measurements simply by reading through a spec sheet. The graphic below will offer you a far better sense of the sensor sizes in the ZS20 and K-7.

Clearly, the 2 cameras offer different megapixel count and different sensor measurements. The ZS20 featuring a tinier sensor is going to make getting shallow DOF more difficult and the Pentax K-7 will resolve more detail as a result of its extra 1MP. Greater resolution can also allow you to crop photos a little more aggressively. The more modern ZS20 should have a benefit in sensor technology.
