Hello all, new to the forum, also a user of the Canon 814 Auto Zoom Electronic. I'm not sure if this warrants a thread of its own and if it does I apologize, but since it's related to this same model of camera, I thought it right to bring it up in this thread. This is probably a long-shot, but I'm looking for the underwater housing C-8 for this camera. It's mentioned in the manual, and I've done extensive Internet research to no avail. I plan on going into Pro8mm at some point and asking them about it, but if anyone has any info here, it would be incredibly helpful. Thanks!
