So i would recomend this case for snorkling, protecting your camera in rain, beach, snow etc…. but it’s not a serious underwater case. There are professional ones that are compatible with the G7 but they cost more than the camera without the storbes…

One more thing to keep in mind that was disapointing about this case was that it did not control the scroll wheel which allows you to manipulate manual focus and lots of other useful controls.

Hope this helps.

All have held up great, and I am in the water with my camera almost every day. I am not particularly gentle with my gear. This housing is well built and seems solid for semi-pro use. (yeah…it may not be as “bombproof” as an Ikelite housing, but it is also much smaller and costs about a third as much !!)

The only drawbacks to this housing are:
1) You cannot use the selector wheel on the back. Minor issue, but there are times when you might want to use, but can’t.
2) The size of the lens barrel on the housing prohibits you from using the flash effectively (the flash for lower right side of the frame is blocked, even with the diffuser plate)for close up/macro shots. I used to get some great macro shots with the flash in the housing for the SD550, and I miss that with this one, since it’s ability to macro focus (as close as the lens on the front of the housing) is far superior to the SD cameras.
3) This housing is VERY buoyant!! I tried the Canon weight kit, and didn’t like how clunky it looked, and it never seemed to stay tight. So I may try to fill up some of the open space in the housing with absorber packs and see how that works. Again, a minor issue, in fact having the housing float is a good thing (see my review for the SD110 housing) !!
(Update 9/10/07: after taking the camera and housing in the water daily for several months, I have gotten used to the buoyancy, and don’t even notice it any more.)

Something you can do to help keep your housing working well are:
1) Rinse with fresh water after each use, it will keep the corrosion at bay.
2) Check, clean and lube the O-ring occasionally. I use a popcicle stick to pry out the ring and clean it (no sharp edges).
3) I store the housing in an inexpensive lightly padded drawstring Coleman stove pouch (no zippers to corrode and break). Also store the housing out of direct sunlight, and don’t leave it sealed up in a car or in the trunk (too much heat can warp the case).
4) When staying in an air conditioned hotel, don’t put the camera into the housing until you have taken it outside and let it warm up. The only time I ever had one of these housings fog up was when I put mine in the housing while I was in the hotel room. It cut short a morning of diving.
5) Get one of those foam float keychains from a boating supply store and attach that to the strap or the housing to make it easier to see if dropped….the housing does float, this will make it easier to spot on the surface.

Get one…..you won’t be disappointed….and get in the water and enjoy it !!!
