Hi Bob, On your first comment I must ask you , good heavens man, don't you know that Sigma lovers and people who use 4x6 minilab prints to "test" lenses will throw sticks and stones at you for making such a statement? Not that it changes the truth of the matter, good god, DUCK! I would generally agree with you on your second thought though I rather fancy my "L" zoom triplets for most work that does not require the fastest glass for creative or available light reasons. As to your third idea that ship has sailed. I went to an all day event where I was introduced to the Olympus E1 DSRL and new Zuiko lens lines, their design and build philosophy. Then allowed to shoot with what ever I wanted to use in the line at one of several studio setups they had with nice props (custom v-rod, custom hot rod lots of good looking models, lots of small coins and jewels for macro shots etc. and then convert from RAW even printed if you so desired. The new E1 when used with the new E1 Zuiko lenses and optional "Olympus Studio" software can take the image data complete with lens, aperture and F/L info and compare it with its database of Zuiko lens characteristics and correct for the lens' flaws. This is pretty neat in action and worked perfectly. You could do the same with Canon lenses but it would be third-party and likely not as precise but probably just as effective in the end.
