You can typically purchase a lens adaptor that would attach the lens to your arm for easy accesibility. I had a professional underwater photographer advise me against that as it leaves the lens exposed to getting bumped, jarred and potentially damaged or worse yet, lost. I used to carry my macro lense that way on my Sea&Sea unit. The plastic housing around the macro lense cracked on me two times due to the lens getting bumped (1X against the boat and the other time while in the rinse bucket) With my new Oly 5060 setup, I'm planning to use a neoprene pouch with a draw string and attach it to my BC and carry in the BC pocket. That will give me the ultimate protection. With the WAL lense representing a major ($329) investment, I want to keep it covered and protected at all times.
