Canon EF 17-40mm F4 L IS USM AF lens with issues, with UV filter, for sale. This is a wide-angle zoom lens for EF mount. The zoom ratio is approximately 2.35, which is relatively large for a wide-angle zoom lens. During the listing, I tested the lens with an EOS R and an EOS KISS X9i, using a ring mount adapter. The autofocus (AF) does work, but the operating sound is loud, and the focus is sometimes achieved and sometimes not. Canon is accepting repairs until February 2029, so please have it repaired if necessary. The aperture and zoom operations were not a problem. A UV filter and front and rear lens caps are included. Please judge the condition of the lens from the photos. Since there are issues with the autofocus, it will be sold as-is, but the price has been set accordingly. It will be shipped via Yu-Pack. Shipping is included.
