This issue - biased tests - would be a fine research issue, which would require (public) access to the econimics of testing magazines.

However I haven't seen another magazine as critical of the EFs 60mm Canon. Lots of people here like the Tamron. There are even a few of us ( not called Godfrey!)have owned decent Sigma lenses so neither of those results surprise me. The French magazine Chasseur D'Image shows photographs of a rectilinear grid when they test lenses. I've always found this useful as a way of seeing distortion. The super new F1.2 85mm Canon L was a lot less impressive than the Pentax 77mm or the FA* 85mm F1.4. both of which you could have for the same price as one of the Canon's. However how many of us regularly take pictures of graph paper!! Peter > >On Sep 3, 2006, at 3:12 PM, P. J.
