Gear Adapter and FDFF Progress

Hello all,

First, let me say how Amazed I've been by your response to this project. It makes me very excited about the future of cinema and video story-telling in general to see how much interest is out there for filmmaking tools. So thank you all for backing us.

As you might have noticed, the goal has been far surpassed. I wanted to let you all know that in spite of the fact that we'll be making a lot more FDFFs than anticipated, we're still on track to begin shipping in March. And you should also know that all of the machining, assembly, and shipping is going to be done right here in Bozeman, Montana.

As mentioned in emails and comments, we will be sending out a survey once the project ends on the 13th of this month, where we'll collect things like shipping addresses and color choices.

And lastly, we now have a gear adapter ready as well. It's a standard 32 pitch (.8 mod) gear that replaces the belt pulley, allowing you to use the FDFF with geared lenses. The gear has 48 teeth and will work with any industry-standard 32 pitch lens gear. If you want one, just add $10 to your pledge and indicate in the survey we'll be sending out that you want the gear adapter as well. In order to work, the gear adapter requires a maximum distance of 2.7 inches between the centerline of your rail, and the gear on the lens. Less than 2.7" is fine, but more than that and the teeth won't mesh. For those who order it, the gear adapter will be included along with the standard belts and pulleys, so you'll be able to make the FDFF work with geared and non-geared lenses. The gear adapter does not include the lens gear, you'll need to have that already, or order one such as this:

So that's it for now. Again, thank you all. I'm looking forward to getting the FDFF into your hands and on your cameras.
