Today I found that the left axle (when facing the camera) for my Phantom 2 Vision appear to have broken.

The result is thatt he camera will still pivot up and down but sags significantly to the right.

Is a repair possible?  I don't see the Phantom 2 Vision camera assembly for sale on the DJI web site.

Any other ideas?

Here's an image that shows where the axles seems to be broken:

You might try a DIY repair since you say that the camera is working other than the broken axle.
Here's a listing for a replacement:

It shows that they have 1 in stock...

Edit: As DJI - Cathy says below, you probably should contact your dealer.
But if they say you'll need the new camera...

Please contact your dealer as a first option for any repair issue.

Otherwise, or DJI.com is your dealer, please kindly contact the nearest support center, support center info. see below:

DJI-Cathy:  I bought my Phantom 2 Vision directly via Amazon USA.   Who then is "my dealer" ?

I know!
DJI does recommend that you not try DIY repairs, but that's a hard decision you'll have to make for yourself...
