Let me see if the omnipotent one can try to explain the problem a little better. Most wet accessory lenses are designed for 35mm native lens such as the popular Inon UFL165AD and Inon UWL100-67mm, Ikelite W20. Quite a few are designed for a native 28mm lens such as the Inon UWL100-28AD, the new Inon UWL-H100 and the Fisheye UWL-04.
Since the S90/95 are 28mm cameras they require NO zooming with the 28mm group lenses listed above and only one step of zoom with the 35mm group of lenses listed above. Since the camera lens retreats during the initial zoom (to about 50mm on the S90/100) this means the camera lens is moving AWAY from the accessory lens and this is never a good thing but since the lens is only a 3.8X the rearward movement is very small initially. The new S100 will require zooming two steps for the 35mm group lenses and one step at least for the 28mm group lenses. Even a mm matters and means the difference between vignetting and blurred edges.
The S100 has some great improvements, unfortunately, the longer zoom and wider FL is not going to play nice with the current crop of accessory lenses, that is my educated statement. Like I said, if it turns out I am wrong, superb, great, works for me.
Maybe there will be a dry port lens or dome made available by the housing manufactures, perhaps they will be able to keep the port extremely close and no longer than that of the former S series cameras despite the 5X zoom requirement and with a little luck, 28mm accessory lenses may work, just may work. Of course, if the buyer has no desire to use an accessory lens, does not matter.
I am not going to be willing to pay more for less versatility even if the camera does have HD which I never use or a cool burst rate. I think this new camera is going to move some people to the increasingly versatile APS sensor size or M4:3 pocket cameras becoming popular now.
