Peter,

I rely on no single source for lens testing information (except, of
course, Erwin! :-)). Over the years I have looked for a consensus of
lens test results to guide purchase decisions, combined with informed
anecdotal performance accounts. This combined approach is more difficult
to determine than a single number, but a truer overall performance
indicator.
