The E90 was announced 5 years prior to the WG-4 and that is a fairly big gap as far as camera tech is concerned. Both the cameras have the same body design (Compact).

Before getting straight to a full comparison, here is a brief summary of how the E90 grades versus the WG-4 in terms of portability, imaging, features and an overall grade.

The following is a preview of the gallery images for Pentax Optio E90 and Ricoh WG-4. The whole galleries are available at Pentax E90 Gallery and Ricoh WG-4 Gallery.

If you're planning to lug around your camera, you'll have to factor in its weight and volume.

Oftentimes, it can be hard to envision the contrast in sensor measurements purely by going through a spec sheet. The visual below should provide you a greater sense of the sensor sizing in the E90 and WG-4.

As you can see, each of these cameras provide the same sensor dimensions albeit not the same megapixels. You should expect the Ricoh WG-4 to produce greater detail with its extra 6 Megapixels. Higher resolution will allow you to crop pictures more aggressively. The older E90 will be behind with regard to sensor technology.
