While the OEM housings like the Canons are "good" to 130 feet (in theory) after a few uses the buttons will become soft and often depress from water pressure at depths as shallow as 60 feet or they will press and not release which locks the camera. They also tend to get stuck. While I do not have the G11 OEM housing I have one exactly like it for my 570. There were also two mold lines which tended to seep water which I had to break over with Micro Mesh.
No fogging issues however, I use the silica tubes or packs. Load the camera when possible the night before and keep it cool. The cameras get warm during continuous operation, not just from the flash. As the camera heats up and the battery heats up moisture is driven off and condensation could form but it has not proven to be a problem with my Canon OEM housing.
Really, I am so singularly unimpressed with the OEM housings and tired of the clunkiness of the Ikelite housings I had to go to a different route for my new camera.
As to Auto modes vs Manual, I kind of think it is the other way, since for years we shot manual cameras that had NO electronics like the Nikonos I, II, III everything was done Manual, we even had to actually focus our own camera, wow. I think the industry has people buffaloed into thinking that Auto modes do not work underwater when in fact, it works very well. I think that is a holdover from real mechanical camera days.
Good luck.
