Getting a sharp, clear photograph of the moon isn’t difficult if you understand what is going on. The moon is very bright and is always moving, so you need to use a pretty fast shutter speed to freeze it. Because the moon takes up such a small amount of the frame, the camera’s built-in light meter won’t have enough information to create a proper exposure, so it’s best to use Manual exposure mode. Start by setting the camera to ISO 400, 1/250 second, f/5.6. After you take a photo, check the exposure on the back of the camera and zoom in to 100% to examine the focus. If the moon looks too bright, increase the shutter speed. If it’s too dark, increase the ISO. If you use a shutter speed slower than 1/250 second, you run the risk of ending up with a slightly blurry moon.
