Lens Design

The 21-element, 14-group optical design provides the clarity needed when shooting with high-resolution X-series sensors, while the rounded, 9-blade diaphragm delivers a beautifully soft bokeh that's further enhanced by the super telephoto compression.

Linear Motor Autofocus

Enhanced by the powerful subject detection algorithms in X-series cameras, the Linear Motor autofocus system delivers fast and accurate performance in near silence. Additionally, the lens features built-in focus presets designed to grant you greater control over your autofocus to capture fast-moving subjects.

• Weather-resistant construction protects the lens against dust and moisture, enabling worry-free use in inclement conditions when used with a weather-resistant X-series camera body.
