The mistake that many people make when attempting to photograph the Moon is that they think they need a super-long exposure. You need to realize that next to the Sun, the Moon the brightest object in the night sky. You also need to consider that you are not photographing things lit by the Moon, but the Moon itself.
As has been said, since the moon is a bright object, your exposure will not be in seconds, but a fraction of a second instead. Use the Sunny 16 Rule where your shutter speed is equal to one over your ISO, and the aperture is at f/16. Since your lens has an aperture range of f/8~f/22, a shutter speed of 1/200th with ISO 200 speed film with an aperture of f/16 should be spot on.
Other options that will produce equivalent exposures to 1/200th @ f/16 are:
1/400th at f/8 (doubling the amount of light entering the camera, but for 1/2 the time) and 1/100 at f/22 (cutting the amount of light reaching the camera in half, but doubling the amount of time) Since lenses are not equally sharp across the range of apertures, I would try all aperture settings to see which image is sharpest. If your lens is like most others, you will see that the best image quality is somewhere around 1 or 2 stops from maximum aperture.
If you have access to a camera that has a spot meter, you can use that camera's spot-metering system to get an exposure just off the Moon's surface. Remember to increase the exposure by about 1 stop since the reflectance value of the Moon's surface is brighter than middle gray, which is what cameras are calibrated to.
Use a tripod since your focal length is sooooo long, otherwise you'll get blurry pictures due to camera shake.
