Sorry if I missed this somewhere the information this morning is just overwhelming.

Can anyone shed some light on the body dimensions in realtion to the xl1/s. Will the xl2 be able to fit in underwater housing made for the xl1?
I assume any old weather covers will fit as the cameras don't look too different in shape/size, and there is always a little extra room in the weather proof capes. However with underwater cases it can get snug.

Thanks

Since the XL2 essentially includes a build in MA100, anything that will hold an Xl1/s WITH a MA100 attached will work. If your case required teh body without the MA100, it's a no-go.

8.9 x 8.7 x 19.5 in. (225 x 220 x 496mm)

I will update this in the summary thread in this forum as well.

thanks guys it looks like it is the same width and height (less 0.8 of an inch) but is about 3" longer. Hmmmm Have to carefuly measure the housing but I think it may be a no go.
