[QUOTE="PhotoAV8R, post: 40273, member: 939"] There's a rule of thumb to remember called the "Sunny 16" rule. When shooting a subject in full sun and setting the aperture at f/16, the shutter speed should be 1/ISO. If you have ISO set at 200, then the shutter speed is 1/200. Note that the rule doesn't included anything about the focal length of the lens. That's because it doesn't matter. You need to study up on the Exposure Triangle. There's lots of info available, but [URL="http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CC8QFjAA&url=http%3A%2F%2Fwww.digital-photography-school.com%2Flearning-exposure-in-digital-photography&ei=brbzTtXMKaaisQK0ubzgAQ&usg=AFQjCNGuarOurWpafcECxaXPty2mpNQo8w"]here[/URL] is a place to start. This is basic information that MUST be understood if you're going to progress in photography. BWTHDIK [/QUOTE]
