The Fujifilm X version weighs approximately 285g and measures about 76.8mm long.

It balances comfortably on compact Fujifilm cameras and is easy to carry throughout a full day of travel, street photography or events. Its low weight also makes it well suited to handheld video and motorized gimbals.

🔍 Excellent Optical Performance

The optical construction uses 13 elements in 10 groups, including one SLD glass element and three aspherical elements.

These components control chromatic aberration, distortion and other optical imperfections while maintaining strong detail throughout the zoom range.

⚡ Native Fujifilm Autofocus

The lens uses a control algorithm developed for communication with compatible Fujifilm X-series cameras.

A stepping motor provides fast, smooth and quiet focusing while supporting compatible continuous, face- and eye-detection functions.

🌸 Impressive Close-Focusing Capability

At 18mm, the lens focuses as close as approximately 12.1cm and provides a maximum reproduction ratio of 1:2.8.

This allows dramatic close-ups with prominent foreground subjects and broad environmental backgrounds. It is useful for food, products, flowers and travel details.

At 50mm, it provides a more traditional perspective and comfortable working distance for tighter detail photographs.

• Everyday content creation

✨ Portrait-Friendly Telephoto End

At 50mm, the lens provides an angle of view equivalent to approximately 75mm on full frame.

This creates a flattering perspective for portraits, couples and event candids, while the f/2.8 aperture produces attractive background separation.

🌦️ Contemporary-Line Construction

Sigma uses Thermally Stable Composite material to provide strength and dimensional consistency while keeping the lens lightweight.

The mount incorporates sealing to help resist dust and splashes. A high-precision brass bayonet provides a secure connection to the camera.
