The Sigma 12-24mm f/4.5-5.6 has a large angle of view (122 degrees super wide angle of view at 12mm along the diagonal axis) and is ideal for shootings indoor as well as landscape photography.

Four Special Low Dispersion (SLD) glass elements are provided for effective compensation of colour aberration, which is a common problem with super-wide angle lenses.

By effective arrangement of lens elements and advanced technology this lens has Super Compact dimensions of 100mm full-length, and 87mm maximum diameter.
It is equipped with Inner focusing system that will keep the length of the lens unchanged while controlling aberration. Equipped with HSM (Hyper Sonic Motor system and offering Full Time Manual Focusing. It has a minimum focusing distance 28cm at all focal lengths. This lens is equipped with an integral Petal-type hood to block out extraneous light

Pros:
Optically excellent
Cons:
Weight, price, 10-20mm is out
Really like this lense but I am going to sell it anyway. An excellent piece of glass providing you get a good sample (mine was fortunately). Crisp shots even at the wide end at the edges.
