The E90 was launched 19 months prior to the GR Digital IV making them a generation away from each other. Both of these cameras have the same body design (Compact).

Before diving into a complete comparison, here is a short summary of how the E90 scores against the GR Digital IV in the way of portability, imaging, features and an overall mark.

Following is a sample of the gallery pics for Pentax Optio E90 and Ricoh GR Digital IV. The complete galleries are available at Pentax E90 Gallery and Ricoh GR Digital IV Gallery.

In case you're going to travel with your camera frequently, you have to think about its weight and volume.

Often, it can be tough to visualize the gap in sensor dimensions only by seeing a spec sheet. The image here might give you a better sense of the sensor measurements in the E90 and GR Digital IV.

As you can see, each of the cameras have the same resolution but different sensor dimensions. The E90 offers the smaller sensor which will make achieving shallow depth of field trickier. The more aged E90 will be behind when it comes to sensor innovation.
