  • Sigma 24-70mm f/2.8 EX DG HSM

    7 out of 10 points and not recommended
    Solid build, sharp image
    front focus by a mile! expensive

    I went into this lens with high hopes, but after doing some focus chart testing it appears my copy is front-focusing by nearly 20mm! That's woefully unacceptable. Now, I'd like to just exchange it for another copy to see if I can get a good one, but...

    The filter size is 82mm which requires approx $200 for a circular polarizer, or more depending on which brand you buy! So adding the $899 + $260 I spent on a Hoya HMC, I can just take it back and exchange it for the Canon 24-70L for the same amount! Since I already own an L lens that has a 77mm filter, the net cost to me is nearly the same.

    This lens has great potential though. when I Live View focus the images were very sharp across most of the focal range... however, there was a fair amount of Chromatic Aberration to be found.
