  • Sigma 12-24mm f/4.5-5.6 EX DG Aspherical HSM

    9 out of 10 points and recommended
    low distortion, low CA, great build
    bulging front element

    This is an extreme lens, to be sure -- the widest rectilinear lens available for an SLR. (Voigtlander also has a 12 prime.) As with any extreme lens, it's going to have a few issues. The design probably requires tighter tolerances than Sigma can deliver on a reliable basis. Even so, it's an amazing lens that delivers very good sharpness, average contrast, and exceptional control of distortion and CA. Focus is fast, silent, and precise. I'm quite a fan of this lens, which I find extraordinarily useful for architectural photography.
