DIY Wireless Remote Follow Focus for 5D MKII

I built a DIY Follow Focus yesterday so here is a link to a YouTube video of it in action. The giant drive gear came from http://www.servocity.com/html/32_pitch_ ... __3_1.html and the Aluminum housing came from Fry's http://www.frys.com/product/2090760?sit ... IN_RSLT_PG . The electronics and servo came from a local RC hobby store. I did not modify any of the electronics or servo. The large 100 tooth drive gear gives the focus gear enough travel to move the full focus range. The 15mm support bracket was made by me in my garage machine shop. You could just by a bracket from one of the vendors from Inda or RedRock. I cut a rectangular hole in the project case and drilled it to match the servo mounting holes. All the electroncs fit nicely inside the case and the case does not block the radio signal. The servo is a 100 oz inch. The project including machining the support bracket took 3, 4 hour days. If you dont make the bracket your self you could finish it in 6 hours or less. Total cost was under $200.00 .

The cameras internal microphone is picking up the servo noise. If you use this mounted on a jib like I designed it for with an external mike mounted away from the camera it works fine.

Brilliant execution but the hardware is a bit noisy!

@paulcotto If anyone is using their camera mic for filming they shouldn't be filming anyway. Great tool!! Thank you for sharing with the rest of us!

How is the servo powered...battery or battery pack? Thanks...good build by the way

Why doing people speak in videos...

[jhamm15]

looks to jerky for smooth focus pulling

Was this video made by a mute person?

[TheOriginalJoeBloggs]

what was the noise on the vid?

[glenndicus]

Well done. For anybody looking to put together a cheap and highly useful tool in their bag of tricks, this has got to be my favorite tool to date.
