This one is from “PureViewClub” and Marc has made three comparison posts comparing similar images and crops from both the Lumia 1020 and 808 PureView. Familiar themes arise out of this comparison as well. While detail capture and sharpness wise both the devices have cameras which are really the best you can get from a smartphone.
In below crops comparisons, 808 image crop is on left and Lumia 1020 crop is on right.Though while capturing close up images Lumia 1020 performs better and captures more details, but also one can see more saturation in the images captured with Lumia 1020. Even in one or two images this saturation is blurring some details at crop level. May be Nokia can provide similar settings of Vivid, Normal etc for color balance control on Lumia 1020 as well like we have on 808 PureView. This will make both schools of thought happy, ones who want punchier colors and others who worship natural colors capture of 808 PureView.
