One of my XL-H1s has gone totally wonky in the viewfinder. The image is jumping up and down like mad, totally jittery, even when in menus. Every now and again, it'll clear up and be fine, then come back. The footage going to tape or out firewire looks fine. I swapped on a viewfinder from another XL-H1 and the problem travelled to the new viewfinder, so it's definitely a camera issue.

Anyone seen this before? I'll pass the camera back to Canon on Monday, but it's unfortunate.

Never heard of that before... that's unfortunate. Please let us know how it goes w/ service.

I have a PAL XLH1 and haver a jittery viewfinder.
I swapped a viewfinder and it still did the same thing.
I think the plug works it way out of the socket. If I press it bacvk in the problem fixes itself for a while.
The achilies heel of the XLH1 is its viewfinder...not up to scratch really

i have the same problem. i'm going to take it back to the shop i got it from tomorow.

I am having the same problem myself,
will probably take it in (and may also see about the PAL upgrade as well)

You push the plug in where it meets the camera? I wasn't able to make mine stop by playing with that plug at all. Odd.

It went off to Canon on Monday, so I'll see what I hear back. My other two XL-H1s haven't shown the same issue, hopefully it's not too widespread!
