Compared to... Ricoh GXR

Below you will find a studio comparison between the Canon PowerShot S90 and the Ricoh GXR with its 10MP CMOS sensor / 24-70mm lens unit (S10). The GXR is designed as a uniquely versatile system camera that offers both large sensor quality and small sensor versatility in a single body. As the lens/sensor units are so different we've decided to treat each one as essentially a different camera. The S10/24-70 module competes in the same space as the S90; the high end, wide angle capable, pocket camera.

Ricoh's ambitions at the serious photographic end of the market are admirable, and it has produced some lovely cameras very much cast from the same mold as the S90, but as these comparisons show - and our review covered in detail - it still has a lot of work to do on JPEG image quality. The excessive noise reduction and overall softness give little clue of what the lens/sensor combination are capable of, and the S90 (which costs about half the GXR/24-70) is better in just about every respect.
