The XF200mmF2 R LM OIS WR Telephoto Lens is made of 19 elements in 14 groups, including one large-diameter super ED lens element and two large-diameter ED lens elements to minimize chromatic aberration. High-precision polishing technology, developed for broadcast lenses, was applied to the large-diameter lens to achieve outstanding image-resolving performance and beautiful booked. The lens also features a new Focus Preset function that instantaneously changes the focus to a preset position, enabling photographers to capture the main subject with ease, and without having to make focal readjustments. Utilizing linear motors, the XF200mmF2 R LM OIS WR achieves fast, near silent and high-precision AF performance, and also features a new mechanism that fixes the motor group when the camera is not in use to reduce any vibrations that may occur. In addition, the lens offers 5-stop image stabilization performance that recognizes shooting conditions and automatically applies optimum image stabilization control. With magnesium alloy construction, the lens is lightweight yet robust, sealed at 17 points and designed to be weather and dust-resistant and to operate in temperatures as low as 14 Degree/-10 Degree.
