Wide to Super-Telephoto Zoom. The Fujinon XA20SX8.5BRM-K3 is a wide to super-telephoto lens for B4-mount, 2/3"-format cameras, such as the Blackmagic Design Ursa Broadcast (B4)z, Blackmagic URSA Broadcast G2 Camera (B4), and Sony PXW-Z750 4K. It has a 20x zoom ratio and a fast maximum aperture of f/1.8 from 8.5 to 113mm, though it’s a slower f/2.7 at 170mm. This lens includes an ergonomic digital servo zoom control.
Internal Focusing Design. This manual-focus lens has an internal-focusing design, which ensures a more consistent focal length when adjusting focus by minimizing the effects of lens breathing.
Fast Zoom Speed. Fujinon’s QuickZoom technology gives you a 0.7-second end-to-end zoom speed. With the push of a button, QuickZoom facilitates a quick shift to the telephoto end to check focus. The lens automatically returns to your selected focal length as soon as you release the button.
