Meet the Lenzhound, the affordable, professional, wireless follow focus system for everybody. Designed and built for filmmakers by filmmakers, the cost/performance value is unmet by any other wireless follow focus system currently on the market. The Lenzhound base kit utilizes an innovative belt-drive system making it very flexible and instantly compatible with most any lens with manual rings. The Lenzhound is designed with professionals in mind meeting the needs of both high-end commercial and smaller independent productions. 

The DB-1 is versatile and can be used for focus, zoom, or iris. The need for remote lens control in today's world of jibs, dollies, gimbals, steadicams and unmanned aerial vehicles, is ever increasing. Unlike other traditional wireless follow focus systems, the Lenzhound does not use servo motors to move the lens. Instead we’ve adopted the use of stepper motors which rely heavily on software to precisely control their movement. This makes them extraordinarily flexible and allows for unlimited rotation.

Many follow focus systems are limited in the amount they can rotate, while the Lenzhound can be mapped to virtually unlimited rotation, allowing use far beyond that of a traditional wireless follow focus system.

This Lenzhound offers flexibility of programming not seen before in the wireless follow focus market. The firmware is Open Sourcemeaning that both the controller and motor/receiver can be customized for your needs or re-programmed for other projects beyond merely pulling focus. (requires code experience. Or, borrow from our user community as it grows and new open source code is made available)

The included firmware features a console which allows you to optimize motor speed and acceleration settings as well as change the wireless channels.

The Lenzhound can work with a variety of power sources, from DC 5V to DC 16V making it easily adaptable to your P-Tap/D-Tap batteries or other power solutions. Our 12V battery packhas enough power to last through the longest of days on set. 

For solo shooter’s we offer a thumbwheel accessory which can be connected to the controller with a standard 3.5mm cable.

With an additional motor the Lenzhound can easily be adapted for 3D lens control. Simply run both motors on the same wireless channel and calibrate simultaneously.

The Lenzhound wireless follow focus system was designed with professional performance while being extremely affordable and offering unprecedented flexibility.
