The WG-4 GPS was brought out 3 years later than the A55 and that is quite a large difference as far as tech is concerned. Each of the cameras offer different body type with the Ricoh WG-4 GPS being a Compact camera and the Sony A55 being a Compact SLR camera.

Before diving in to a comprehensive comparison, below is a brief introduction of how the WG-4 GPS scores vs the A55 when considering portability, imaging, features and an overall grade.

Below is a sample of the gallery pics for Ricoh WG-4 GPS & Sony SLT-A55. The entire galleries are available at Ricoh WG-4 GPS Gallery & Sony A55 Gallery.

For anybody who is going to lug around your camera, you should factor its weight and dimensions.

Looking at size and weight, the portability rating of the WG-4 GPS and A55 is 90 and 67 respectively.

Usually, it is difficult to envision the gap between sensor measurements merely by looking at specs. The photograph below might provide you a much better sense of the sensor dimensions in the WG-4 GPS and A55.

All in all, the two cameras enjoy the same exact MP but not the same sensor measurements. The WG-4 GPS provides the tinier sensor which should make achieving shallower depth of field more difficult. The more modern WG-4 GPS will have an edge with regard to sensor technology.
