Description — Sigma 50-100mm f/1.8 DC HSM
The Sigma 50-100mm F1.8 DC HSM Art Lens delivers a 50-100mm telephoto zoom range with a remarkable constant maximum aperture of f/1.8, making it one of the brightest zoom lenses available for APS-C format DSLR cameras. That consistent f/1.8 aperture across the full zoom range gives photographers real flexibility when managing exposure and depth of field, whether shooting portraits at 100mm or pulling back to 50mm for environmental compositions. The lens accepts 82mm filters, consistent with its large optical design.
Weighing in at 1,490g, it is a substantial lens that reflects its optical ambitions. Focus options include both autofocus and manual focus, giving shooters the ability to switch modes based on the situation. The lens is offered in the Sigma SA mount.
It carries no image stabilization, so handheld shooting at longer focal lengths will require steady hands or faster shutter speeds. For APS-C DSLR shooters using Sigma bodies who want maximum aperture in a telephoto zoom, this lens makes a compelling case.
