While the dp2 Quattro image looks perfectly fine overall, the above 100% crop from it (click for full size) shows a weird behavior. The letters on the light blue store signs have poor resolution, with the yellow bleeding into the blue background. It looks more severe on the top right banner. In comparison, the DP2 Merrill reproduced these areas flawlessly, showing the usual strong acutance. The black-and-white image of the same scene shot with the Quattro has barely noticeable letters on the store sign.
It surely is not something most users will really care about (I haven’t seen it in on any other image so far), but it’s intriguing enough to be noticed. Is it another SPP fantasy? If not, can it be fixed in firmware?

Note: Dicahub referred to it as the “Beer Garden issue” because the affected text says “Keio Asahi Beer Garden”. Everyone is free to call it “yellow-on-blue issue” or whatever 🙂
