Here's what I would recommend:


10-22


24-70 f2.8L or 24-105 f4L


70-200 series or a 70-300 IS





There you go. You got yourself covered. Being a traveler myself, I had the same combo as above (10-22 + 24-70 + 70-300 IS). Why did I go for the 24-70 than 24-105? Because of the 2.8. Sure it'll be a big and weight very heavy but that's the most used lens at about 75% of the trip. Plus a great performer in low light. 70-300 IS is there more for the reach than the IQ. I use this for about 5% of my trip. Why? You're always on the move. Unless you're going to a concert, zoo or other areas that need telephoto, you won't be using this a lot. 10-22, the only UWA on your crop body. I use mine for about 20% of my trip especially in tight areas.
