I rented a Sigma 10-20mm from Leo's this past weekend for my trip to Tofino...and it was a good thing I did...I had a blast with this lens and I think i definitely have at least a few money shots from the 500 or so shots I took

(I hope at least haha)
The Sigma 10-20 goes for $25/day or $100 per week (for the Nikon).
Oh yeah, Leo's is on Granvill St. between Helmken and Nelson
