Motion Dogs have come up with the Lenzhound wireless lens motor system. While the majority of wireless follow focus systems on the market have been out of reach for a lot of shooters the Lenzhound is a very affordable entry level system aimed at the DSLR and indie markets.

How the Lenzhound actually performs given its low price point remains to be seen. For shooters with a limited budget it does appear to offer excellent value for money. I have not personally seen or used the Lenzhound system so my advice would be to wait for some independent reviews to come out before purchasing.

This from Motiondogs:

The Lenzhound is a flexible, wireless and user-friendly method of extending lens control to an assistant camera operator or “focus puller” enabling professional, cinematic filmmaking. The Lenzhound system is clean, simple and inexpensive, consisting of the handheld remote transmiter unit (RTX-1) and the motor/receiver unit (DB-1) which attaches to the user’s camera rig. The DB-1 lens motor is targeted towards DSLR and video cameras employing lenses with manual operation rings, but is applicable for cinema-style lenses with the optional Cine-Standard gear attachment. The system features open source, Arduino compatible firmware which enables the user to program a powerful array of custom senngs for other, improvised camera-movement set-ups.

According to Motion Dogs president, David Thayer: “One hurdle in the wireless remote follow-focus arena, is that the FCC requires a certification process for wireless radio devices. We have navigated that challenge and our wireless device is not only FCC-certified, but also competitive cost-wise, even with cabled and manual follow focus systems. We are also very excited to enter the unmanned aerial system (UAS) or “drone” market.”
