Ya, is he on vacation or something? I'm not sure I could get a 14 if i wanted it, forget about the stuff RioRico throws out here.
I find it hard to take a site like DxO seriously though. There are no good Pentax lenses according to DxO. The higherst rated Pentax lens is the new 35 2.4, which is a great lens, but better than every otehr Pentax lens? Really? It's rated at 15 out of 50, right down in the poor range. They have tested no 3rd party lens on Pentaxes. Most Pentax lenses are rated under 15, the highest on other systems are rated at 35. The Tamron 90 is very highly rated on the Nikon D4, 10 points higher than any Pentax lens... I just don't know what to do with these ratings. There is no way I know of to compare. The haven't rated even one 3rd party lens on a Pentax, so, you can't even guess what their numbers mean, except that if you want a good lens, you should be buying anything but a Pentax. In other words, there may be uses for them, but I fail to see how they have any kind of testing standards, their numbers are complete fabrications at the worst, or useless for Pentax users at best. Every one on the Pentax forum and the guys at photozone have the FA 100 WR and the Tamron 90 rated as pretty close.
Rating of the Tamron 90 on a D4= 25. Rating of a D FA 100 WR on a K-5 14. You know, I really don't even want to know what DxO's explanation is, I'm sure it would just hurt my head. This despite the fact that the D4's sensor rating is 89 and the K-5s is 82. But to break this off cleanly, their full of it up to here when it comes to Pentax. I can't figure out what their numbers mean, and i doubt anyone else can. And I bet the reason they don't post any third party lens reviews on Pentax K mount lenses is that it would completely discredit everything they've published. I can't believe they don't know they have a problem with these numbers. They're trying to sell product. I think they're covering their own sorry asses by doing things the way they do. Their K-5 sensor rating was a bone thrown to Pentax to keep them from challenging their fudged ratings. They are making money from this some how. I wouldn't be surprised if the corporations are paying for the ratings. It makes as much sense as anything else you see on the site. Pentax paid for a good rating for their body, and probably couldn't afford to have their lenses top rated.
