Canon EF 35-135mm f/4-5.6 USM - Canon EF Mount

A versatile all-in-one zoom, this lens covers everything from wide-angle to moderate telephoto. It features a Ring-type USM for fast, quiet autofocus and allows for full-time manual focusing. The optical design includes an aspherical element to help correct aberrations, making it a capable general-purpose lens for travel and everyday photography on full-frame or APS-C bodies. Used examples should be checked for smooth zooming, as the internal cams can wear over time. Ensure the USM motor is functioning silently and that the manual focus override works without resistance. SDS verifies the absence of internal optical issues such as balsam separation or heavy dust ingress which can occur in older multi-element zooms.
