Hi Terry, thanks for the extra info. I'm a newbie when it comes to camera lenses.
Looks like a very good performer for the price.
And thanks Kearn, i'll take the time to read that review before I make any rash purchases!
Does the focal length range of a zoom lens make a difference to its quality? ie: is a 12-24 going to be generally easier to produce (better quality?) than a 17-70?
