Pentax K-7 vs Pentax RZ10

Here, we will be looking at the Pentax K-7 and Pentax RZ10, one being a Advanced DSLR and the latter is a Small Sensor Compact and they are both created by Pentax. The resolution of the K-7 (15MP) and the RZ10 (14MP) is relatively similar but the K-7 (APS-C) and RZ10 (1/2.3") posses totally different sensor dimensions.

The K-7 was brought out 21 months earlier than the RZ10 which makes them a generation apart from one another. Both cameras feature different body design with the Pentax K-7 being a Mid-size SLR camera and the Pentax RZ10 being a Compact camera.

Before delving into a thorough comparison, here is a short summary of how the K-7 scores against the RZ10 for portability, imaging, features and an overall grade.

Here is a preview of the gallery photos for Pentax K-7 and Pentax Optio RZ10. The entire galleries are available at Pentax K-7 Gallery and Pentax RZ10 Gallery.

In case you're looking to lug around your camera frequently, you should think about its weight and size. The Pentax K-7 provides outer measurements of 131mm x 97mm x 73mm (5.2" x 3.8" x 2.9") with a weight of 750 grams (1.65 lbs) whilst the Pentax RZ10 has specifications of 97mm x 61mm x 33mm (3.8" x 2.4" x 1.3") and a weight of 178 grams (0.39 lbs).

Remember, the weight of an Interchangeable Lens Camera will differ dependant on the lens you have chosen at the time. Here is a front view measurements comparison of the K-7 versus the RZ10.

Using dimensions and weight, the portability score of the K-7 and RZ10 is 60 and 92 respectively.

More often than not, it is very difficult to visualise the difference between sensor measurements merely by reviewing a spec sheet. The graphic below should provide you a much better sense of the sensor sizing in the K-7 and RZ10.

Clearly, each of these cameras come with different megapixel count and different sensor measurements. The K-7 featuring a bigger sensor will make shooting shallow DOF less difficult and the Pentax K-7 will deliver greater detail having its extra 1MP. Higher resolution can also enable you to crop shots a good deal more aggressively. The older K-7 is going to be behind in sensor tech.
