I have not been starting a fuss every night perhaps

I suppose it may be because everyone got their rigs set up nicely and are no longer as dependent on this forum for advise. I remember most of the fuss was around getting the g series and s series canons set up for underwater use.
Perhaps Canon has not come up with anything significantly different in setting up. There is enough information in these threads to get set up properly with the g or s series canons.

Dunno Oz...........Again, used to be well over a hundred here(UW Photography Forum--ALL camera forums) logged in and over 25 in the UW Videography forum---now it's less than 60(currently 58) & 13 respectively.......Maybe everyone(except me) is out shooting their brand new rigs & not showing us their results........hmmmmm----------just saying.......

nah, people(UW photographers in specific) love a good dog fight.........Keeps the blood a boiling(& going) & prevents arteriolar & athero- sclerosis from forming.....
I did some comparisons of postings in the Hawaii 'Ohana this past June (I think) and the previous June, and my conclusion was that the spring "upgrade" caused regulars to go cold turkey long enough to be "cured"

Have to say, the upgrade is really a downgrade---...Now, there may be some new ones signing up for this site(SB) daily, but fewer ones are coming to it (here) each day.......ie--UW Photography, ~60 on now & UW Videography, ~15 on now......Something ran these 'good folks' away, & it wasn't cause all of a sudden they learned 'everything there is to know' about shooting UW pics/videos.......
Who ever was resposible for this step backwards ought to feel real proud of themselves---right now........lolololol......

Well, we could start by some more useful discussions....
Here's one I could use....
I shoot video with a canon 5d mark II in Aquatica housing. I shoot full manual.
Focusing is something I do when I reach the bottom after jumping in, and I decide how far away I want to be shooting video--sort of what will my subject be.... If I want to shoot the corals and small fish, I will be trying to get as close as I can without rubbing my dome port on sea fans in the way of the shot
This is a close focus, so it is hard to get perfect...just moving a litte further or closer tends to injure the video product.....so this is one place auto-focus would be nicer, because it "can" be faster, when there is lots of light, lots of contrast, and no repetitive patterns that confuse the artificial intelligence of the camera sensors....Typically, for a crips manual focus, I have to pick a suitable subject and distance, get stable, hit the magnify button twice to go to times 10, then pull focus.....I cant see focus reliably without the magnifying...but this takes some time you don't always have, and means your stable period must last longer--also difficult where currents or surge is pushing you around.....auto focus would take less than 1/5 th the time.
So, does anyone have knowledge about whether it would "DAMAGE" the canon 5d or the lens ( 16-35 canon) if I leave it on auto focus, and use auto focus a few times per dive, and manual focus a few times per dive...I don't have a contol on the housing, that will change the switch on the lens from AF to MF....my thinking so far, is that if I manually focus the lens when it is set to autofocus, that this will somehow damage the servo or something related--if done too often. I must have read something about this somewhere.
Does anyone know the deal with this ?

no it will not damage it. That lens has full time manual focusing which means you can override the AF with the focus ring by design while still in AF mode. I do it all the time on my telephoto canon lens for my rebel xt.
It's designed to be used that way.
