I am considering purchasing the Sigma 70-200mm f/2.8 EX DG HSM II Macro Lens. The problem is that many reviews point out that the lens has front focus problems, at least on a Canon mount. But those reviews date back to 2008, so things could have changed.
I have also been told that newer Sigma lenses (2010 and later) should have dealt with their focus problems.
Is that so? Can I purchase the lens and trust it to focus correctly? I have the 500D which does not have micro-focus adjust.
