The Hither dial is important in closeups; it controls how close to the lens an object can be without distortion. For instance: your character is holding a glass out toward the camera as if to say "Cheers". As you focus in on the face, with the line of sight being along the exxtended arm, the glass and then the hand will break up into weird cubist fantasies...... unless you adjust the Hither dial. In general, setting Hither to 0 will get everything to show properly. (Actually, I don't know why you'd even want to leave Hither at the default setting; maybe far-distant shots look better that way, but I don't ever need a far-distant shot!)
