The new Olympus MZ ED 7-14 f/2.8 PRO and MZ ED 8mm FE PRO lenses are very popular. They are sharp, fast, well-made and open up new abilities to shoot underwater in low light (see our reviews here and here). There are a number of ways to house these new lenses depending on how you shoot, or what dome ports and parts you might already own.
