Wide to Super-Telephoto Zoom. The Fujinon XA20SX8.5BERM-K3 is a wide to super-telephoto lens for B4-mount, 2/3"-format cameras, such as the Blackmagic URSA Broadcast G2 Camera – B4, Blackmagic URSA Broadcast Camera – B4 and Sony PXW-Z750 4K. It has a 20x zoom ratio and includes a 2x extender that effectively doubles its focal range. Its maximum aperture is a fast f/1.8 at 8.5 to 113mm, while it’s a slower f/2.7 at 175mm. 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.
