Micro Lens for Canon G9

[dancewithethan]

I would like to add micro lens for my canon G9, any suggestion?
also, how can I adjust dept of field on the G9? or the best setting to tank pictures of Corals and fish?

Thanks

Canon calls it "macro", Nikon calls it "micro". To adjust your DOF, change the aperture. The "A" setting on the control knob allows you to change this setting. "S" allows you to change the other setting, "shutter speed", and "M" allows you to change both.
