DIY remote focus on EX1 and alike
on Mar 29, 2010 at 5:35:35 pm

As owner of a Steadicam Pilot and a EX1 I bumped into the problem of keeping focus. The autofocus function makes its own decisions about what to focus on. These decisions often do not correspond with my intentions. At 6 mm everthing is sharp. But when I zoom in, the focus becomes critical and one can’t without a remote focus system.
These systems don’t come cheap, so I decided to try to build one myself.

I documented the system in a PDF and a YouTube movie.

It is an outline of a working system. When you decide to build your own, feel free to improve it or make your own additions. Share your insights please.
Enjoy!
