t-thugI can get ether one for 250$ with a filter. My buddy has the canon 10-18 but I saw that other o e with a lot of good reviews too. :/
get this lens, 12-24 f4 im assuming you're mostly shooting during the day so f4 wont be an issue.
If you want better low light get the 11-16 f2.8, little more expensive but worth it
ditch both the 10-20 and 10-18.
