After recieving both cameras for review I thought I take the R10 with me to get used to it a bit before reviewing it. The first impression is very good and I really like the camera. More will follow in a review but I am very glad Ricoh dropped the 'soap-box' design, flimsy build and controls from the R5 and improved the interface from the R7. While I have no extensive experience with the previous R series cameras, I think the R10 is the best yet. The great build and design alone are worth the upgrade.
This picture is straight out of the camera with minimal cropping and contrast adjustment.
