I'm just starting to research photography gear and the Olympus E-PL3 and Olympus Housing has piqued my interest. When I look at the packages being sold, some of them say that a zoom ring is included. Can someone tell what a zoom ring is? If I buy the camera and housing as a non-package, can I get the zoom ring separately? Is a zoom ring needed? As you can see, I'm in my infancy of learning about photography gear. I just ordered a book on underwater photography, but I'm not sure it will get too specific about the gear. Thanks for your feedback.
