How to tips on choosing a camera housing?
Digital Camera is not enough for underwater photography activities. To be safe for use in water, the camera needs to be watertight protective. Personal protective equipment is commonly called HOUSING / Home. Housing is also present on the buttons that are mechanically linked to the button on the camera. Therefore, in the water we can perform like we did the camera settings on land photography. Thus it becomes very essential Housing in underwater photography activities. Strength of the material as well as high accuracy is needed in the production process of housing. Therefore it is not uncommon to housing prices to be quite expensive, even more expensive than the price of the camera itself.
Housing is only suitable for one type of camera only, Housing is not general, and it means the camera is only compatible with a model of housing allocation. Example Canon Powershot G series camera housing, the camera cannot be used for other models. Therefore, before buying a digital camera, make sure that the Housing still commercially available for purchase. Buy a camera directly with housing to prevent unavailability of housing in the future.
Specifically for DSLR cameras, you also have to buy additional ports accordance with the lens you choose. Each lens has a compatible port, and therefore specifically for DSLR cameras you can only carry one type of lens into the water.
Non-DSLR cameras usually have a function that includes a macro lens and wide angle. Therefore, one of the advantages of this type of underwater camera in addition to body lean, you can shoot macro and wide angle camera with 1 unit only.
If you are going to buy Housing for prosumer camera types, currently available aplenty casing / housing producers made themselves at relatively low compared with those of other manufacturers (3rd party).

The best thing you can do is buy a 3rd party brands like housing Ikelite, Sea & Sea, Subal, etc., which are made from high quality materials and are designed for use in the activity of Scuba Diving.
Note also the procedures for using the O-Ring and Grease in a watertight housing system in the manual book each tool. The thing to remember is that the silicon Grease is not the primary means to prevent leakage. Leaks can only be prevented by the use of a rubber O-ring in accordance with the instructions manual.
