A subject with clearly defined lines naturally makes for easier and more accurate focusing. DEPTH OF FIELD The depth of field is the range of distance between the nearest and the farthest points of the scene that are in sharp focus. It varies with the focal length chosen, as well as with the apertu re and the range. Depth of field is shallow with a long focal length (25 mm to 40 mm) and a wide aperture, and at short range. Depth of field is great with a short focal length and a small aperture, and at long distance. Consult the depth of field table which shows the available 22 range at different focal lengths. OPTICAL SUNSHADE ACCESSORIES The sunshade supplied with the camera must always be used. It will eliminate any risk of reflections from the front element of the lens.
