Canon has introduced a new ultra-wide angle zoom lens, the RF 16-28mm F2.8 IS STM, designed for full-frame mirrorless cameras like the Canon EOS R8. The lens offers a bright maximum aperture, compact design, and affordability compared to professional lenses. It caters to enthusiasts with features like customizable control ring, autofocus/manual focus switch, and optical stabilization. Despite some lens distortions, the lens delivers sharp images and is suitable for various photography styles. However, its limited zoom range and pricing raise questions about its appeal compared to other Canon RF lenses.
