5. HV20 Focusing Tool
2 years ago
The HV20 comes with a manual focus roller, which is a good thing. However, it is a bit awkward to operate.
Others here and in HV20.com have come up with clever ways to get around this problem. They usually involve larger wheels that are mounted on some assembly. The wheels are designed to touch the roller and turn it by way of friction.
Here is a minimalist friction tool that can be used to accomplish the same task (well, perhaps with enough practice). It is small, portable, cheap, and light-weight.
Enjoy!

PS: For HV30, use black silicone tubing.
I swear the things we come up with when faced with restrictions. It is like we all a bunch of jail birds looking for a way out lol.
Great stuff!
Now I just have to get an HV20...or 30...
XD
At the start I thought you were going slit the tube and wrap it around the edge of the ruler. That way you would have "marks" to hit for your focus pulls.
I stopped by a thread and saw this. I'm working on a website for a client but I'm going to take a break and go down the street to the hardware store to get the tubing.
Thanks for the DIY!
I did go to the hardware store and get it. Total cost? $0.30. THIRTY CENTS. It's $0.15 per foot, so I got two feet just in case.
It works good. I think I'll rough up the surface a little to give it a little tooth. Otherwise, I'll just have to apply a little more pressure when I run it against the focussing wheel.
Hobby stores should have them, or check with your local automotive store, but do insist on silicone.
You gotta love the simple things
:) Focusing Stick :D I like the name :)
Thanks again, scon

You know what they say, sometimes genius appears in simplicity.
Thanks a lot.
Long ago I decided to share it with the Vimeo community instead of patenting it.
The other half of the manual focusing problem is the tiny low res display. Did you do anything to solve that ? (attach larger display?) Were your pictures perfectly sharp anyway? (looks good but for definitve answer the full HD has to be seen)
I now have a GH1. Focusing is more critical on it. The focus assist is nice; it auto magnifies as soon as you touch the focus ring.
