OK, so I bought a new, well, new to me (actually duplicate, since my original rig is exactly the same and still functional) camera and housing, and it included a macro lens. The camera is a Fuji E900 point and shoot type camera, ikelite housing. The price was right, so I couldn't resist.

Having never used any additional lenses underwater before, I'm wondering: do you have to put the camera into macro mode when you use the external macro lens?

I'm looking forward to trying it out, but would appreciate any pointers from those that have more experience than I
Thanks!!
