I've recently acquired an Olympus 60mm macro lens, and I'm looking for tips about how to best setup for underwater use, as this will be the first time I'll be diving with a dedicated macro lens with this camera. The various options for setting 0.19-infinity etc, I've noted in some other threads that 0.19-0.40 is suggested by some as the best to reduce the hunting time for the lens when using a CMC/SMC - is this the same when neither of those are equipped? or is full range preferred?
Also - I've also ordered the focus gear for this - is this not necessary unless one is manual focusing? I'm going to use it temporarily behind the 9-18mm 4" dome, but will be getting the 30mm extension ring for my 35mm port (which I have for the 14-42mm EZ - does anyone use this combination?
