  • Sigma 17-70mm f/2.8-4 DC Macro OS HSM

    8 out of 10 points and recommended
    large aperture, fast focus, little CA, nice bokeh. good build
    VERY apparent vignette, you can pretty much see it in every shot

    I like this lens overall, except for the fact that if you crank up your contrast, blacks and whites during PP, you can see the vignette at 4 corners. It's very easy to see that it appears in most pictures.
