Kai from DigitalRev has completed his video review of the brand new Canon EF-S 10-18 f/4.5-5.6 IS STM lens. This $299 lens for APS-C shooters seems to be getting a lot of praise, most of which is based around its extremely affordable price.
I have used the lens a couple of times and find it to be nearly as good as the EF-S 10-22 f/3.5-4.5, especially as an ultra wide angle walk around lens in cities. Pair it with an EOS Rebel SL1, and you have a pretty good light weight hiking setup as well.
