Interchangeable lenses are precise optical instruments and indispensable tools for the working professional. These tools must perform to match or exceed expectations in rugged conditions, rain or shine, indoors or out. Canon considers feedback from the professionals who actually use our lenses to be an important factor in the effort to boost lens performance. Professionals often have to work in severe conditions, subject to dust, wind, rain and snow. When Canon introduced a newly developed series of dust- and water-resistant super telephoto lenses in 1999, it assumed from the outset that its products would have to perform under severe conditions like these.
Today, the effort to meet these exacting standards continues. A rubber ring was introduced at the mount connection, to seal the gap between camera and lens from the elements when the two are attached. Highly dust- and moisture-resistant construction was also used for the focus ring, focus preset playback, and other moving parts. Switch panels and drop-in filter holders were rubberized. In today's age of digital imaging, the performance of professional lenses will be tested in an ever-growing range of environmental conditions, just as profesional demand that they should deliver superior imaging performance. Canon’s pursuit of excellent dust and water resistance continues in the RF L-series lenses. The entire system including lens, body, and accessories are designed to satisfy the most exacting demands of professional image makers.
* This cannot guarantee complete exclusion of water and dust from entry. The lens must be attached to the camera body to ensure dust- and moisture-resistant performance.
