Photozone´s reviews are the most important out there. I would like to know before I pay $1000 and to me that´s more important than what the pope ever says.
I prefer the reviews of Kurt Munger, not so much numbers. Maybe Photozone could remove the ratings at all. There is always a bias in this ratings. There are many studies about ratings, and actually they show that ratings often depend more on emotions, how good was you last meal etc. than what you actually measure.
Look at the Lumix G 7-14mm f/4 ASPH, it got 4 stars. Do you get so much better pictures from it?
The only aspect which bothers me is the decentering.
