Were you shooting at the 18 or the 55mm focal length of the lens? What focus point do you have selected?...Normally the AF will "hunt" as it's called, when there is not enough light for the contrast detection system to properly work...Most AF systems have trouble focusingwhen the aperture selected is F5.6 or smaller (which is what it is when using the 18-55 at the 55mm length. Tubes & converters reduce the amount of light striking the sensor & can cause problems as well...
