I read a complete report in their magazine about how they are testing lenses, and it looks like serious to me. However, their lens reports do show one weakness: there are no separate graphs for sharpness and contrast. They combine both into one chart per aperture. This is excellent for the average public, but not for those who want to go in-depth. Star ratings should only be compared within a given class of lenses (lenses within the same aperture class) because for stars they take the average of the quality at three apertures. As you would expect the "light giants" that open at 1.4 are often penalized in this way. Another point: they not only give star ratings for optical/mechanical quality, but also for price/performance and c=F4te d'amour (=3D subjective feeling about how they like a given lens). I could except the price/performance ratio, but have sometimes problems with the c=F4te d'amour, which is of course subjective. They also continually note about Leica (and Contax for that mather) lenses that they are way too expensive compared with almost-as-good offerings form other manufacturers.
