I would like to send a complaint letter to Panasonic about the horrible auto iris in the AG-HMC40, and try to convince them to release a firmware update to address that problem (yes, I know, they will probably laugh at it, but at least I can try.)

Does anybody know that address? I can't find them at their broadcast products website.

I found the address on their brochure:

Panasonic Broadcast & Television Systems Company
3 Panasonic Way, 4E-7, Secaucus, NJ 07094

(201) 348-5300

Professional Video Cameras and equipment from Panasonic (http://www.panasonic.com/broadcast)

Great, thanks!
