This lens boasts a 14-group, 21-element lens construction that delivers best-in-class image quality. Five ED glass elements and one Super ED lens element, whose optical performance rivals that of fluorite lenses, thoroughly reduce axial chromatic aberration, resulting in best-in-class image quality. With a maximum magnification of 0.19x at the telephoto end, you can enjoy telemacro-like imaging. Best-in-Class Image Stabilization: 5.0-stop Image Stabilization. At the telephoto end, the lens offers a focal length equivalent to 609mm (35mm equivalent), enabling stable handheld framing and significantly reducing camera shake. Additionally, when the lens detects panning, it automatically switches to vertical-only image stabilization. High-Speed, Quiet AF Drive: The linear motor delivers high speed and high-precision AF, supporting fast-moving subjects. Its quiet operation makes it ideal for capturing images of concerts, plays, and other events. The lens features a focus limiter that limits the lens's operating range when focusing. Activating the focus limiter enables faster AF when shooting subjects more than 5m away. Compact and Lightweight Design: The compact and lightweight design weighs less than 1.4kg. Even when combined with the FUJIFILM MX-T1 premium mirrorless camera, it weighs less than 2kg. Furthermore, the lens has been optimized for optimal weight balance when attached to the camera body, reducing the burden on handheld shooting and carrying.
Dustproof, Weatherproof, and Low-Temperature Operation (-10°C) with Fluorine Coating: With a total of 13 seals in 12 locations on the lens barrel, the lens is dustproof, weatherproof, and can withstand temperatures as low as -10°C. This allows for worry-free shooting even in tough outdoor shooting conditions. The front element is coated with a fluorine coating that is resistant to dirt and easy to wipe clean. Its water-repellent properties allow for worry-free shooting in wet or dusty environments.
Lens Hood with Locking Window and Polarizing Filter Access Window: The lens hood features a sliding polarizing filter access window, allowing for easy operation even when the hood is attached. The hood locking mechanism also locks the hood in place, eliminating the risk of the hood accidentally falling off.
Compatible with the 1.4x Teleconverter: Compatible with the already released FUJINON Teleconverter XF1.4XTCWR. When attached, it covers a focal length of 140mm to 560mm (equivalent to 213mm to 853mm in 35mm format) with an aperture of f/6.3 to 8. Phase-difference AF is also possible when attached.
