I took a shot of the moon this morning. ISO 200, shutter speed 1/250 second, f11, 55-200 zoom lens, tripod. Two weeks ago I couldn't have told you what those things mean, but after reading the "Dummies" book, now I do. I took 7 shots, all in "manual-settings" mode. My lens has a switch for either manual or auto-focus, and I used both. This shot was auto-focus, but the manual-focus shots were just as sharp.
