Fuji X100 vs Ricoh GXR
Just published in my Fujifilm Finepix X100 review is a new page comparing the Fuji X100 image quality to the Ricoh GXR, as well as an expanded discussion of the merits of the X100 vs Ricoh GXR + 28mm lens module.
It is my view that the Fuji X100 image quality is superior to the Ricoh GXR in noise, color and digital artifacts.
