Neither lens can replace the other. If you want the best detail for wide field astro tomorrow night, the 12-40 becomes a dud.

True. I didn't mean that one replaces the other... just that I am glad to get that extra stop of light to make my efforts (at 12mm) a bit more bright to allow me to pull greater detail.

What I'd really like... is a 9mm f 2.8 for under $400.

There's a lot of folks ahead of the both of us, in that line (despite the potential for such a lens to be a dog).
