Focusing • With the lens attached to the camera, the infocus indicator in the viewfinder will not display properly. When focusing, do not rely on the infocus indicator. • With high-magnification macro shots, the working distance (distance between the front of the lens and the subject) becomes very short. Be careful not to bump into the subject. • To prevent camera shake, use a tripod and the Remote Switch (sold separately). • For magnification-priority macro photography, a focusing rail (commerically available) will make focusing easier. • With high-magnification shots, the viewfinder image will darken, making it difficult to focus. Using Angle Finder C (sold separately) will make it easier to focus. • To check the depth of field, refer to the Depth-offield Table or use the camera's depth-of-field preview.
