    Canon RF 200-800mm F6.3-9 IS USM

    200–800mm · f/6.3–9

    Overview

    The Canon RF 200-800mm F6.3-9 IS USM offers an unparalleled zoom range to 800mm in a relatively compact, handholdable 2kg body with 5.5-stop IS. Optical quality is good, with three ULD elements reducing aberrations, but the slow f/6.3-9 aperture forces high ISO in low light, producing noise and reduced dynamic range. Build is weather-sealed, though the non-removable tripod collar and fiddly switches are drawbacks. It suits wildlife, sports, and aviation photographers needing reach at an affordable price.
