Good example (I sent three others back before keeping this one!) of the Tokina 11-16 F2.8 for Canon APS-C Sensor DSLRs. Selling as I have moved to Full-Frame.
Excellent condition, very good in low light for storm structure - here is an example - 11 mm at ISO 1250, and it was getting quite dark out (hand held):
There is a Mark II version coming for Canon-mount but it won't be available until July (press release also mentions a 90,000 Yen price - I doubt it will be that high but will likely be more expensive than the current version)
$600 + shipping and Pay Pal fees. Canada - USA only.
