Hi Kiuilop


My first hand experience is with the EFS 15-85 and it does takes sharp pictures. I've read/heard that either lens that you are asking about is not much of an improvement (if not worse)than your current lens. Rather, the two "bang for your buck" zoom lenses I've heard people talk about are your current kit lens and the EFS55-250 f4.0-5.6 IS. Other than that, maybe look at picking up another prime lens? I've heard great things about the 85 f/1.8, 100 f/2 and that the 24/28/35 mm (non-L) lenses aren't bad.


Good luck,


Brant
