Here's my Tokina 12-24 f/4, this is my landscape lens and for those ultra wide angle shots that
gives off the grand view. I'm very happy with this lens, got it for a great price and I love the
image contrast and the perspective it gives me! At 12mm, I have to get used to how wide this lens
is and how much is captured through the lens!
I carry this lens and my Tamron 28-75 most of the time, as it gives me the distance from 12-75mm.
Currently looking into the Canon EF 70-300mm f/4-5.6 IS USM, but need to do more research on it.
