Negative Positive
Title: Cannot Focus
Review: I was very disappointed with this lens. I purchased it to replace my Canon 28-135 IS as it was too bulky plus I would get a bit more zoom.Close in this lens takes some good shots, I posted a few at pbase. The problem was that at anything over 150mm everything out past 15 - 20' was a blur. I tried the 28-135 at similar focal lengths and the IS beat it hands down. Granted there is that 'IS' function, but even with it off it was much better.I tried this lens on both my Rebel (A300) and my Rebel XT (A350) getting the same results.End result, Tamron 18-200 is going back (just packaged it with the RMA# right now). I am keeping the IS, I've grown to re-like it. Will either get the 70-300 IS (which is why I am out at Amazon right now), Canon 100mm Macro, or the Sigma 105mm Macro in its place.I would NOT recommend this lens to anyone.
Is the review positive or negative?
