JVC GY-HD200U Lens Problem?
on Aug 23, 2013 at 5:40:52 pm

This is a pretty general camera/lens question but it is a JVC camera so I figured I'd check here. The company I work for has a JVC GY-HD200U camera with the Fujinon Th16x5.5BRM Lens. When I get a tight closeup on an object I can focus on it clearly but, when I zoom out the focus point changes. If I'm more than fifteen feet away from anything I can't keep it in focus. I assumed the backfocus was off and tried to test it out but the test passed (perhaps I don't know an intricate enough test). Is this something I can fix on my own or something I should take in to a repair shop? Or rather is this just an issue I will have to live with?

Thanks for any and all help!

Evan - Sounds like an out of focus back focus.
Check out this page for a correct proceedure to re-focus the back focus:

Good luck.

P.S. You might want to download the back focus test pattern on the page to make it easiest.
