The Fujinon ZA17x7.6BERD-S10 lens 2/3″ HD 7.6-130mm extender 2x zoom with focus Servo – B4 mount is a high-quality lens designed for professional cameras with a B4 mount, often used in television broadcasting and filming. This lens features a 17x zoom range, with a focal length from 7.6 mm to 130 mm. It also features a 2x extender, which effectively doubles the maximum focal length to 260 mm, allowing for greater flexibility in image composition, especially in situations where higher magnification is required. The ZA17x7.6BERD-S10 is constructed from high-quality materials and incorporates advanced optical elements to minimise chromatic and optical aberrations, ensuring sharp and detailed images. The maximum aperture of f/1.8 at 7.6 mm and f/2.7 at 130 mm allows for good performance even in low light, while maintaining high image quality. One of the distinctive features of this lens is the Servo focusing system, which enables precise and smooth focus control via an electric motor. This is particularly useful during dynamic shooting, where the focus must be adjusted quickly to keep the image sharp. The operator can control the focus with extreme precision, making the lens ideal for shooting sports events, documentaries or live television programmes.
