Just got the above lens today for my Canon 550D. Was using the kit II lens (18-135) for more than 3mths before i research on what lens to get to compliment what i have, as well as my upcoming Spain's trip.

Result of numerous nights of research point to this lens.

Now the verdict....

one word says it all.... WOW!

if i can choose the second word... IMPRESSIVE!

I tk it's gonna help a hell lot for beginner (like myself) with this faster, brighter lens.

Go try it!
