From a photographers point of view I can say it ticks a lot of boxes...but from an astrophotography point of view...forget it at F1.2!
...edge coma and lateral colour abounds....given the money...it's a shocker.
At F2.8 it tightens up a lot....begging the question " so many $$$ for a F2.8??"
Bang for buck is Sigma's new 12-24mm zoom. Seems designed for Astro!
Bugger all lateral colour. Low coma...and extraordinary value for money.
(...OK I'm a lucky guy and have one of these as well)....but watch this space...I've just ordered Canon's new L-series 11-24mm...not a typo...that's ELEVEN-to-24mm.
Early reviews are simply gushing in praise.... we shall see!

Ive got the Canon EIGHT-15mm L f4
. You get 180 deg round pics with that (at 8mm), not really mid field, but really interesting for out-there TL.
Also 24mm f1.4 L which I was told when I bought it a while back was the duck guts for Astro, but sadly it suffers seagulls around the edges.
