If you would like to do underwater photography with your SLR or DSLR, this is what you need. I bought this to take scuba diving on vacation and it worked great! I've included a sample picture that I took in the ocean.
This underwater housing has room for a SLR/DSLR camera, a mounted flash, and a battery pack. It can hold a lens with up to 77 mm filter threads. The lens attaches to the glass of the housing for clear photos. You will need to use a lens that has an internal focusing system because it will be unable to turn externally.
The clamping rails are non-corrosive and seawater resistant. The main housing is made of double laminated PVC.
There is a valve you can use to add or release air after the clamping rails are sealed. It also comes with a lead weight that you can add inside the bag if it is too buoyant.
Rated for dives up to 155' depth.
I have performed a test before listing and there are no leaks.
Camera/lens/flash not included.
