I bought those Sigmas used, so I very likely can sell them for the same price as what I purchased them for (they really keep their resale value quite well when you buy used). I'd be open to trying this G2 and considering swapping back. Would likely just sell the 24-35 and keep the 14mm, for astro and other low light situations. May also compare this new one to the Canon 16-35 f/2.8 III. I look forward to Dustin and others getting their mitts on these lenses for some comparisons.
It's really remarkable how Sigma and Tamron are running circles around the first party lens release schedules.
Maybe we can test it on Photokina?
Disagree IMHO:
This is overwhelmingly why I prefer Canon's 16-35s over Tamron here -- the not the AF or build-quality, but the front-filtering. It's vital for me. I prefer to have a closed camera from the elements and then build up my filtering as the scene requires.

For astro the coma was almost non-existent.
Entirely fair. Didn't mean to imply their position was wrong -- it's just not my position. My sensibilities are not the world's, and I hope it didn't come across that way.
Sorry for not being clear.

And the low vignetting just smokes the Canon 16-35 f/2.8L III.
That said, if you want an all-purpose UWA zoom instrument and not just an astro tool, your decision is much harder. I still prefer my 16-35 f/4L IS to all other options as a general instrument, but my list of general uses is probably not the same as yours. For instance, I don't shoot astro and I rarely shoot sports (and almost never with UWA FLs).

Everything I have ever read says the image quality is fantastic with that Canon lens. Although I really liked the Tamron, I always wished I had bought the 11-24 or the 16-35 Canon. I actually went in the store to buy the 11-24(It had just been released), but ended up with the Tamron. I like the 16-35 for the exact reason you state: front filter. I never got around to buying a system for the Tamron.
Honestly, Adam, I just don't have a use for a UWA much. That may have to do with the fact that I lived in the desert at the time and it made things look all the more distant. Here in the DFW area I think one would be much more useful. I even have trouble justifying the keeping of my 35mm prime because the 24-70 is so good even if slower. Really need a second body instead of a new lens. :)
