I can use the stocks lens but I need a minimum of 8-12 inch away or it won't focus.

I which they would make a "macro mode" like on compact camera, my Canon S90 can take picture less than 1 inch from subject.

Might lose a stop. But you'll be shooting f4 - f8 so not a big deal.

You can get less than an inch away there are typically 3 rings so you can use combinations to get the focal length you want. I have lens against the glass or hovering just above the water.

Macro rings are a great inexpensive way to get into macro before you decide to go whole hog.
