A constant f/2.8 aperture across the 76-213mm equivalent zoom range pairs with a Triple Linear Motor for fast, near-silent autofocus and 5-stop optical stabilization. The fully weather-sealed, all-metal construction and Nano-GI coating ensure sharp, contrast-rich images even in harsh outdoor conditions. This lens is best for portrait and event photographers who need reliable, professional-grade telephoto reach on Fujifilm X-mount bodies.
