You can get this from my sig, but here's my current setup (major components):
Canon 70-200mm f/2.8L IS
Canon 24-105mm f/4L IS
I definitely prefer L build and FF compatibility (looking to buy a 5D within the next 12 months as a second body) but still consider EF-S if it fits the need.
A couple more comments. I find 24mm wide enough, unless I want to go really wide. I am also looking for very low-light options (read "f/2.8 not good enough") So... help me spend about $650:
- Canon EF-S 10-22mm f/3.5-4.5: W---I---D---E... talk about fun with landscape shots, etc... then again, if I'm going to travel, I may be able to purchase anyway on "travel" expenses (or at least that'd be my argument!)
- Canon 50mm f/1.4 & Canon 85mm f/1.8: Two primes for a good price!
- Sigma 30 f/1.4 EX DC: under budget, but fast and wide... 1.6x crop only, though (plus ? for $200?)
- Canon 580EX II: Compensate with good flash instead of fast lenses? Pair with 50mm f/1.4 or 85mm f/1.8? Or get more "flash" gear in total?
- Canon 35mm f1.4L
