Finally got around to playing with the Jag35 Wireless Follow Focus V2 prototype. First time getting it working (somewhat). There's a procedure you need to do before throwing on something like this on your camera, so i'll need to run through the manual and get things ironed out.
Each motor has a certain amount of rotation, so you have to line up your focus and zoom rings to have enough movement either direction. There's also adjustments that can be made for how much travel will be achieved when spinning the knob for focus or moving the slider for zoom. Not enough time tonight....
Jehu from Jag35 talks to Olivia and shows off their new Wireless Follow Focus system balanced on a Steadicam Merlin along with a Hacked Asus WiCast to send video to the focus puller. Jag35 has different version motors available depending on how much torque you need for the lenses you'll be using, giving you more affordable options. If you don't require a Wireless system, the same motors work with a tethered remote which they showed us on a seperate shoulder rig. After handling the units at NAB, they are very responsive, quick, and accurate for a Follow Focus on a budget. Gotta get me one of these. More information found below.
If you're looking to tackle a home made Wireless Follow Focus project, you might want to give VImeo member Phillip James a holla. For the past few months, he's been working with Arduino to design his own WFF, and seems to have worked out all the bugs. It definitely looks like all the parts are in the right places, and appears to be very precise in movement. Take note that one thing inexpensive WFF's are known for is the amount of noise it can generate. WFF's have a place and sound should always be captured seperately (like on real sets).
If you're not up to the task of a DIY the most inexpensive one to first hit the market was from Jag35. Although it worked pretty well, it's been polished up quite a bit lately. Pricing is unbelievably cheap if you've ever shopped around a for one. Prices are available following the link below.
If you're wondering if the above video is legit, it sure seems like it. The manufacturer is found at this website at https://www.plcelectronicsolutions.com. If you're thinking about getting something like this, get ready to dish out over $1500.00 for just the Receiver. Which means you still need the lens gears, the motor, and of course iPhone not included. I think everyone might be better off going with the the new RedRock Wireless Follow Focus seen at NAB.
