You decide on the aperture you think will give you enough DOF and you select that. You then have to follow the instructions removing the lens while holding down the Fn button with the camera STILL SWITCHED ON. That way the aperture will not be set back to it's wide open position by the camera.I have never used this method as I have plenty of good manual lenses with faster apertures (f1.8, f2.8 etc.) than the kit ones. As I prefer manual focus with macro that works for me.A good quality manual lens (say $25 for a Zuiko 50mm f1.8 or $10 for a Helios 2/58) a set of tubes ($10) and a manual to 4/3rds converter ($10) gives quality macro.Pete</blockquote>
