I've just been reading the review for this lens, and seem to get the impression that this is less extensive than that carried out on Olly's original 4/3rds lens, unless this is down to the way this information is displayed nowadays. However I am digressing a bit, because what I am hoping we will see soon, is a group test involving the 'Old' 7-14mm, Panasonic's version and the new Zukio f2.8 7-14mm zoom. Since AP have indeed tested all three of these separately, and I can never remember seeing any of these lenses being included when 'group' tests are done, even though Olympus's less wide zoom was included in some 'Group' tests, one has to wonder why, this lens was NOT also included. I'd like to know, if at the f-stops where these lenses do all match, how they compare. By the way, if getting hold of the 4/3rds version is a problem, (and the 4/3rds to m4/3rds adaptor) I would happily supply you with one, so it's no use using that excuse!
