That is true. It just shows that GR lens is on par with other prime lenses. Just not as a star performer like some people believe. Still a good lens to be sure.That is true but basically every lens (even really nice ones) on a non full frame body on that tool loses a ton of sharpness at F8 as well, so I don't really think it's a point specifically against the Ricoh, especially once you throw in the size and weight considerationsWhen it stepped down to F8 which often used for snap focus to get wider depth of field, the resolution decreases throughout the frame. Center 2000 and edge 1500. Not as good as people believe. I still love my GR.the Ricoh stopped down to f4 on there starts dipping into purple, the only setups there with much purple are some of the lenses on full frame bodies, so considering the size of the GR that's pretty acceptable for me (and of course, when we stop pixel peeping and start looking at the images, they're as sharp as I could ever need or even notice)No offense, but what are you folks talking about? Blue means sharp.https://www.dpreview.com/reviews/le...e&lensId=ricoh_gr&cameraId=ricoh_gr&version=0"With a DxOMark score of 21 points, the GR lens is an excellent performer overall, with low levels of both distortion and vignetting – often weaknesses in wide-angle lens like this. Sharpness at 13P-Mpix is high too, considering the maximum is 16P-Mpix"dpreview tested GR with DxOMark back in 2013 which shows GR is not as sharp as you would like to believe. Don't get me wrong, I am very happy with my GR.
It then goes on to link to graphs showing that the lens is not very good at all. At which point, I gave up.
Yes, I gave up after seeing this chart also. There are a lot of Nikon lenses can easily out perform GR lens according to what this chart is showing. However, my GR takes sharp pictures good enough to my eyes, but probably not as sharp as some people like to believe.
