Their tests are flawed. <<<<<<<<<< Not necessarily true. Erwin has posted that even he finds Pop Photo's tests as being sound. It just depends on whether you find the parameters on which they base their evaluation to be relevant to your usage of a lens (I, for one, do). Specifically, on October 19, 1996, Erwin posted the following (excerpted from a longer post on lens tests) to the LUG: The POP Photo methodology is optically sound. They analyse a lens on five or six parameters they deem important and then use a weighted average to arrive at the SQF values. It is the selection of parameters and this weighting that undervalues the Leica lenses in most cases. What they measure and the way they measure it are in itself correct.
