Pentax RZ10 vs Pentax WG-10

Its time to look a bit more closely at the Pentax RZ10 and Pentax WG-10, one being a Small Sensor Compact and the latter is a Waterproof and they are both designed by Pentax. The resolution of the RZ10 (14MP) and the WG-10 (14MP) is pretty well matched and they come with the same exact sensor measurements (1/2.3").

The RZ10 was announced 23 months prior to the WG-10 which makes the cameras a generation apart from each other. Each of these cameras offer the identical body type (Compact).

Before getting straight into a detailed comparison, below is a brief synopsis of how the RZ10 grades versus the WG-10 for portability, imaging, features and an overall grade.

Following is a preview of the gallery images for Pentax Optio RZ10 and Pentax WG-10. The whole galleries are available at Pentax RZ10 Gallery and Pentax WG-10 Gallery.

If you are planning to lug around your camera regularly, you should take into account its weight and volume.

Oftentimes, it is very difficult to see the gap between sensor measurements only by reading through technical specs. The visual below should give you a stronger sense of the sensor sizes in the RZ10 and WG-10.

As you can tell, both of the cameras offer the same exact sensor sizing and the exact same MP therefore you should expect similar quality of pictures but you may want to take the production date of the products into consideration. The older RZ10 is going to be disadvantaged when it comes to sensor innovation.
