A constant f/1.8 aperture across the 50-100mm zoom range delivers full-frame equivalent depth of field control on APS-C sensors, paired with 7 ED elements for high clarity. The internal zoom and Hyper Sonic Motor provide fast, quiet autofocus without extending the barrel, maintaining balance on a gimbal. This lens is best for portrait and event photographers who need a fast telephoto zoom but don't require stabilization.
