Ahboy ah......
Look at your Equipment list
You already own a this 2 lens....
EF-S 17-55mm f/2.8 IS USM | EF-S 18-55mm f/3.5-5.6 IS
Why you still want a 18-270 or 18-200....??? :think:
You should go for other range lens or prime lens.
like that you are wasting $$$$......
The problem is i am a lazy person ... ;p
Any better suggestion ?
