i hope for an updated version of this lens, IS or not.
the performance of this lens is purely disgusting. whoever who says it's good, simply havent been shooting day in and day out and/or havent been looking at offerings from other brands. it's horrendous to know that such a bread and butter lens is known to be soft at 2.8, have AF issues, and with a barrel that can extend (hence more prone to damage and failure?) come on, it's 2010 already, canon ought to update this piece.
with that said, the nikon version is simply the best. comes as no surprise, since it's the latest to reach markets.
