There probably should be a site rule that allows moderators or someone like that to edit and/or delete posts about equipment where the advice is completely and obviously wrong and is likely to mislead people badly. Well, no, there shouldn't be such a rule, it would be controversial and unworkable, and in any case, other posters can always chime in to provide correct information - and if you don't read all the way to the end of the thread before you spend your hard-earned, it's your own fault!
IS makes a huge difference, and as a bonus, the new lens has even sharper optics.
This is just plain wrong. Hopelessly wrong. The EF-S 60mm macro is universally regarded as a superb little lens. I have never, ever seen or heard a bad review or a bad report (apart from the nonsense above). Lots of AP members own this lens, and produce excellent work with it.
