I was hoping for this lens to be a bit faster. As it is though, I can't see a compelling reason to get it over the 17-70/4. 70 vs 85mm isn't that big a difference, and it's slower.
edit: But let's not write this lens of completely. Many mention the 18-135, but from what I've seen in e.g. the
PF review, that lens is not so great anymore at 70mm or longer, esp. in the corners (yes I have been using my 17-70 to do landscapes at 70mm and f/8 and appreciate sharp corners). It is weather sealed, and if it's sharp, it may still be a good proposition.
