It really helps if you can maintain a constant mag factor when comparing lenses in this fashion. Most 35mm lenses are far from ideal at f16-22 though your results still surprise me a little, I wouldn't have thought that the differences would be that significant. It would be interesting to perform a similar test with all lenses at f5.6 :-) Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http:/home.swiftdsl.com.au/~distudio/publications/ Pentax user since 1986, PDMLer since 1998
