4K EFP box lens, 70x zoom, 2x extender, built-in stabilizer, ARIA, RBF, 2/3" B4 mount, without trunk

The Fujinon UA70X8.7BESM-T45 is a 4K Premier Box Lens designed for high-end broadcast production. It provides exceptional image clarity by improving the MTF (Modulation Transfer Function) even for low-frequency objects that are common in the image. It features a built-in image stabilizer.

It offers a 70x zoom, with a focal length ranging from 8.7 to 610 mm (which becomes 1220 mm with the 2x teleconverter). Thanks to the floating focus system, it maintains high resolution throughout the zoom range, ensuring sharp and detailed images.

The combination of fluorite ED (extra-low dispersion) and Super ED elements minimizes chromatic aberration and provides clear and sharp images. To make the most of the extended dynamic range offered by HDR cameras, reflections have been rigorously eliminated thanks to the special surface treatment of the lenses and faithfully conveys the "blacks" that are important in rendering video images.

Bayonet with B4 mount for broadcast cameras with 2/3" sensor. Supplied without carrying case.

User benefits

• Multi-group zoom system: by using a multi-group zoom structure, spherical aberrations are suppressed throughout the zoom range from wide angle to telephoto, ensuring high image quality
• The use of a high-precision, large-aperture aspherical element ensures a high MTF all the way to the edges
• More than three times higher lens surface processing precision than HD, contributing to better image quality
• The newly developed anti-reflection coating (HT-EBC) ensures a reflection of 0.2% or less across a wide wavelength range, minimizing surface reflection of the lens and achieving truer blacks
• Suppression of ghosting and flare by optimizing the internal shape of the lens barrel and its surface treatment
• Natural bokeh due to the use of a 9-blade round iris
