I never bothered with DxO and not because I am a Canon user. I simply believed that they just made interesting software products for lens correction (bundled with specific cameras). I have no opinion on their camera ratings (I learned a lot though in this forum by reading various debates). As far as lenses are concerned, I find this score silly at least. We do not get information about performance at specific f-stops, center, edges or corners, flare, vignetting, CA etc. When I need a lens review I check photozone.de and the-digital-picture. I will continue ignoring DxO for ratings (and I have all cameras I need for the moment). Isolated feature tests and comparisons could be interesting though.
