Ouch $$ Dropped 3 lens myself over the years, a full metal Tokina 28-105 manual focus lens 4 feet onto concrete, the zoom ring got a little stiff but eventually worked loose without any repairing, I kept using it for another 6 years. The second lens was the Tamron plastic (OK, "high tech composite") 28-200 AF super zoom, only from 1 .5 feet onto concrete, the zoom helical barrel shattered into 3 pieces, it cost just over half the cost of a new lens to repair, trade it in after the repair for the EF28-135 as soon as I was able to. I then dropped the EF28-135 from waist high last year, again onto concrete (why can't I drop a lens on turn or better yet on foam?), it required barely CDN$100 at Canon Canada to change one little part in the lens to return it to service. It would be interesting to see just how much the repair estimate for your Sigma lens is.
