Well, the 18-55 actually has very good resolution. If you want to get more range, the 18-135 and 17-85 will do that for you, but the sharpness is not any better than the lens you already have (in fact, in some cases it's worse).



  • Cheap
  • Sharp
  • Zoom

<div>Pick any two. Want sharp and cheap? Stay with your 18-55, but you wont get much zoom.</div>

<div>Want sharp and zoom? Go up to the much more expensive EF-S 15-85, but it wont be cheap.</div>

<div>Personally, I chose the Tamron 17-50 f/2.8 because I wanted it to be very sharp and have a fast f-number. If you can consider using multiple lenses, that is what I would encourage you to do. But if you would really prefer to have one lens, try to get the 15-85.</div>
