The Fujinon HA42x13.5BERD-S48 is a lightweight, portable high-definition telephoto lens built for EFP (electronic field production) work, pairing a 42x zoom ratio with a 2x extender for long reach from a single, self-contained lens body. Digi-power servo with digital servo remote control gives full servo studio control, suited to robotics, jibs, tower cams, teleconferencing and other applications where optical quality counts — the same servo system that lets the lens be driven remotely without an operator at the barrel.

A 42x zoom built for full servo control

The lens's own focal range runs 13.5–570mm; bring the 2x extender in and that stretches to 27–1140mm. Maximum relative aperture holds at f/2.8 through 13.5–307mm before falling to f/5.2 at the 570mm end. Fujinon's Digi-power servo, with digital servo remote control, delivers full servo studio control for robotics, jibs, tower cams, teleconferencing and other high-optical-quality applications.

Internal focusing and precision zoom handling

Internal focusing moves the lens's inner group without changing the lens's overall length, keeping the assembly stable while focus is adjusted. QuickZoom flips the lens to full telephoto and back at a touch, so focus can be checked before pulling out to frame; a zoom limiter restricts zoom travel to a set range, and auto-cruise zoom lets the operator set a fixed speed for a smooth, constant-rate zoom.

Compact enough to travel, built to stay steady

At 5.4 kg the HA42x13.5BERD-S48 is light and portable for a lens of this reach, with a minimum object distance of 2.8m and an M127 x 0.75 filter thread. Built-in OS-TECH is included as standard on this model — a compact, self-contained option for productions that need long reach without adding weight to the rig, whether that rig is a solo operator's shoulder mount or a fixed robotic head on a studio floor.
