Sigma Contemporary 10-18mm f/2.8 DC DN 10-18mm
Weighing just 260g with a constant f/2.8 aperture, this 10-18mm zoom delivers an ultra-wide 15-27mm full-frame equivalent field of view in a weather-sealed, travel-ready body. The fast internal focus system and 117mm minimum focus distance enable dynamic close-ups with smooth bokeh from its 7-blade diaphragm. This lens is best for vloggers and landscape photographers using APS-C Sony E-mount cameras who need a lightweight, low-light capable ultrawide zoom.
