The Tokina 11-16 suffers from lensflare really, really badly. As you're shooting outside anyway: get the Canon 10-22. Muuuch better flare control! The fixed 2.8 you're not gonna use anyway, you'll stop it down badly.
And on-topic:
Maybe get a Takumar 50mm f/1.4. You're gonna need to manual focus anyway, and stopped down it's awesome, you can't beat this lens for the price (like 80$?)
To the people saying 17-40 on a crop: Seriously? Why the hell would you do that? Short range, no IS (not that important, but hey). The high f-stop is ok because of shooting outdoors, but it does make it a lot less versatile. Get the Sigma 17-50 OS or Tamron 17-50 over the 17-40 any day. The Sigma is siiick anyway and even rivals the 17-55 which costs twice as much. I've even seen extensive comparing and pretty much everyone agreed the Sigma 17-50 rocked all other mid-range zooms. The only thing the 17-40's got speaking for it is the weather sealing (bfd...)
Good lenses for/from all ranges:
- Canon 10-22
- Samyang 14
- Tamron 17-50
- Sigma 30 f/1.4
- Canon 50mm f/1.8 (used this goes for 70$, good lens)
- Canon 85mm f/1.8
- Canon 70-200 f/4
- Sigma 70-200 f/2.8
