From what I understand and believe I've read here you can buy just the clear covers. I think they are about $35 each. If you do a search you should find a write up here on taking them apart. It is not an easy project and requires boiling the assembly to get the glue loose. There was also a concern over what type of glue/epoxy to reattatch them with so that they would not leak. If you do replace yours, please take lots of pics and share your progress with the rest of us whos lenses have hazed! Its definately a lot cheaper to replace the lenses than it is to replace the assembly.
