flutteringaway evadingtheflyingnapkin About that lenses: of course the Sigma lenses are not bad (with the exception of the 50 EX macro which IS bad .. as is the EF-S from Canon to have another example). They are affordable and better that some Canon lenses of the same (low) price range. One just have to live with their limits .. or buy a Canon L-lens. Even if you like Sigma lenses (not saying that's wrong) .. there is a reason you own Canons, isn't it? :) Thanks Donald and have a great day!! :-) Tom
