A 29–320mm equivalent on APS-C Canon EOS models, this lens ($700, street) boasts the broadest zoom range of any interchangeable optic from Canon to date: 11X. A high-end kit option for EOS 50D owners, it probably owes its existence to the phenomenal success of Nikon’s 18–200mm f/3.5–5.6 VR Nikkor. And with the debut of Tamron’s far-reaching and stabilized 18–270mm f/3.5–6.3 lens (tested in this issue), an 11X Canon may be just the beginning. Two glass-molded aspheric elements and two Ultra-low Dispersion (UD) elements control spherical and chromatic aberrations, respectively. And this new lens is internal-focusing, with only four of its 16 elements used to focus. Because these internal elements are significantly smaller than the nonrotating front elements, the lens focuses faster, drains less battery power, and also accepts filter-ringmount accessories.
