The Lenzhound Wireless Follow Focus is an ultra-economical single-channel remote lens control system offering a professional level of accuracy and durability. All our systems have our 3XT Upgrade for the motor and newly designed wireless transceiver that gets up to 1000-foot line-of-sight range for rock solid reliability on set.

Several configuration options are available including our unique belt-driven solution for driving photography lenses without 32-pitch teeth. This means that no lens adapter is required to use this remote follow focus with your photo lenses. For all your cinema, we offer an industry standard 32-pitch / 0.8 mod cinema gear. Best of all, these two configurations are easy to switch between!

The Lenzhound RTX-1 controller offers an ergonomic design inspired by smart phones. The RTX-1 provides real-time access to acceleration and speed parameters to achieve focus pulls that would be otherwise impossible. Only the Lenzhound provides this unique control over speed and acceleration during focus pulls. This flexibility also extends to the controller’s four Set/Recall buttons that provide quick access and control for perfectly repeatable focus pulls. The RTX-1 boasts incredible battery life lasting over 32 hours with fresh AAA batteries. No waiting for a recharge, ever.

The Lenzhound DB-1 motors feature flexible power handling and can accept battery or wall-wart sources from 8-16VDC. The motor has plenty of torque for driving heavy cinema lenses. When paired with one of our 3800mA 12V battery packs the DB-1 motor typically achieves over 10 hours of operating time and over 20 hours on most V-mount batteries.

This system is the world’s only Open-Source wireless follow focus available on the market, encouraging developers to hack, modify, re-purpose it for applications we have yet to imagine.
