Auto focus on the book or box or make sure the ruler is in the scene. Take a picture with the lens set at minimum f stop. If the 6" mark is sharp, you are good to go. If the ruler mark less than 6" is sharp, you have front focus. If the ruler mark greater than 6" is sharp, you have back focus.</p></blockquote><p></p>
