The Canon EF 20-35mm f/3.5-4.5 USM was a consumer-grade ultra-wide angle zoom lens introduced in 1993. It offered a useful wide-angle range, starting wider than typical standard zooms, making it appealing for landscapes and interiors. It featured a Micro USM motor for relatively quiet autofocus (though not as fast as Ring USM). While not an L-series lens, it provided a more affordable entry into ultra-wide photography within the EOS system.
