[QUOTE="spb_stan, post: 683660, member: 43545"] The DxO ratings are not measuring many of the traits that have been identified as being related to the perception of sharpness Some of the most well-regarded lenses do not score as high as some which have less desirable traits. There is a lot more to the perception of sharpness than simple optical resolution. A good portrait, one that most people would prefer when comparing the output of different lenses in the same session and lighting, absolute resolution not strongly correlated. One has to shoot lenses under conditions usually used to get a sense of what it actually delivers. You are suggesting that selecting a set of hi-fi speakers is best done by comparing specs? That has never been shown to correlate to perception. Or a painting needs to be judged by resolution(pigment particle size). I am an engineer and numbers are important in a lot of engineering but they have a lot less to say about art. Photography is art regardless of how technical it has become. Few people with very high spec cameras ever produce a desirable image that communicates something the viewer values. [/QUOTE]
