Thanks for your input. Iv spent a little bit of time with a 60D, had i bought one a few months ago id be more than happyif i was still shooting with it today, but to purchase one now feels a bit wrong, its just a bit of a weird time for the top of the line canon aps-c market. I also considered a 7D but i still have the same dilema. As you say, CES is a just over a week away so im going to wait and see if announcements are made but from what iv heard even if they are announced next week they may only be available sometime mid 2013. I really hope that wont be the case as iv got quite an itchy 'trigger' finger at the moment (ha) and dont feel i could wait too long, im just hoping an announcement is made next week and they release the product soon after otherwise im still stuck with this predicament.
As far as lenses are concerned i was thinking of getting a 17-85 but my friend has one and he claims the barrel distortion at the wide end is a bit much. The 28-135 was another option but on a crop sensor i fear it wont be wide enough. The 15-85 seems like a good choice, i dont mind spending a little bit more for better glass. There doesnt seem to be much choice for a mid range variable zoom (walkaround lense).
So its one of those 3...or perhaps a third party?? Sigma, tamron?
Sigma's 17-70mm OS seems not bad and being updated shortly too. (I don't personally use this lens so can't say more)
New Sigmas are alleged to be produced with better quality control so hopefully less variability in IQ.
They've sometimes suffered from de-centering issues in previous product that could otherwise be good but hit-and-miss on whether you'd actually get a "good" copy of one.
Canon's EF-S 15-85mm quickly became a favorite of mine on the 60D as a general purpose, walk-around and everything else lens. It's a bit bothered by CA within a few mm of either end of the zoom range and occasionally has severe corner shading that can't be corrected (combination of filter ring and IS system near limits on some shots) and even some mushy extreme corners at the wide end. But none of this is enough to make me leave it at home until I can determine whether a competitor's equivalent performs any better.
IMO, I've never liked the 17-85mm for its distortions and the 28-135 is not nearly wide enough, even on FF, for my preference.
