While it's a bit hard with an X-700, I find that off-camera flash is the greatest thing when doing macro. You can go completely handheld and it doesn't matter if the camera is moving when the shutter goes off as long as your plane of focus is right. And you can shoot happily at f/16 in the dimmest light.

If you have a recent AF minolta like a 5 or a 7 (I assume other brands too though extra dongles or cables might be required), they support wireless auto-exposure flash and it works very very well.
