Look how big that front element is... now imagine it needs to let in another stop of light...

That is an exposed aspherical element, they all look like that as do fisheyes. Wide angles usually have the largest front elements. The exception is large aperture long telephotos.

There are lots of places where the subject is very close or very wide and the widest wide angle never seems like enough. This can include indoor shots to city streets.

I own the closest equivalent Sigma lens to this (the 12-24 II) and that is big and weighs a ton and is actually slower than the one above (f4.5-f5.6). Believe me, if you wanted that as an f2.8 you'd have to want it VERY bad.

Where is Sigma 12-24 big?

Its a fairly substantial lens (slightly heavier than the 16-35 f2.8L) and the heaviest non-telephoto I've owned.  A faster version would probably be around a kilo I reckon.  I like it a lot but its a lens you think about whether it goes in the bag or not before you lug it around all day.
