When the air temperature inside the bag reaches the surrounding temperature, take the lens out. Cleaning the lens • Do not touch the surface of the lens directly. • If the lens gets dirty, brush off dust with a lens blower and wipe with a soft, clean cloth (Cleaning Cloth KK-CA (optional) is recommended). • Do not use any organic solvent, such as thinner or benzine, to clean the lens or the camera cone. . Names of parts . Attaching/detaching the lens To attach the lens 1 Remove the rear and front lens caps and the camera body cap. 2 Align the orange index on the lens barrel with the orange index on the camera (mounting index), then insert the lens into the camera mount and rotate it clockwise until it locks. • Do not press the lens release button on the camera when mounting the lens. • Do not mount the lens at an angle. To remove the lens While pressing and holding the lens release button on the camera, rotate the lens counterclockwise until it stops, then detach the lens. To attach the front lens cap Attach the front lens cap fully, and pull the string. . Focusing When using the auto focus, the camera focuses the lens automatically. When focusing manually, set your camera to the manual focus and rotate the focusing ring while looking through the viewfinder. The focus signal in the viewfinder indicates the current condition of the focus. Note This lens is a wide angle type. Make sure the shoulder-strap, your fingers, etc., are not in the frame when a picture is taken. Depth-of-field scale When focus is set on a subject, anything at that same distance will appear sharp, and anything within a certain range before and beyond the subject will also appear in focus; this is called depth of field. Depth of field depends on the subject distance and aperture you choose and is indicated by the lines on the depth-of-field scale corresponding to the aperture. • The depth-of-field scale and depth-of-field table are for 35mm-format cameras. The depth-of-field is shallower when you use Digital Single Lens Reflex Cameras equipped with an APS-C sized image sensor. 21 Depth-of-field table (in meters) f/2.8 f/4 f/5.6 f/8 f/11 f/16 f/22 . . 2.87 . 2.05 . 1.47 . 1.06 . 0.77 . 0.57 . 0.42 1m 1.44 0.77 1.78 0.71 2.72 0.64 11.5 0.56 . 0.48 . 0.40 . 0.33 0.5m 0.57 0.45 0.61 0.43 0.67 0.40 0.80 0.38 1.10 0.34 2.55 0.31 . 0.27 0.3m 0.31 0.28 0.32 0.28 0.34 0.27 0.36 0.26 0.39 0.25 0.46 0.23 0.63 0.22 0.25m 0.26 0.24 0.26 0.24 0.27 0.23 0.28 0.23 0.30 0.22 0.33 0.21 0.39 0.20 0.2m 0.20 0.20 0.20 0.19 0.21 0.19 0.21 0.19 0.22 0.18 0.23 0.18 0.25 0.17 . Filter This lens has four filters, which can be changed where appropriate. Make sure to have one of the filters set when shooting, since the filter is part of the optical system. NORMAL: This is for general use. Use this filter, unless filter effects are desired. O56: This is effective for use in shooting distant landscapes with enhanced contrast, when monochrome shooting or using a black and white film. A12*: This is for use in shooting under the sunlight with a tungsten film. It prevents pictures from becoming blue, and maintains accurate color rendition. B12*: This is for use in shooting under tungsten lighting with a daylight-color film. It prevents pictures from becoming red, and maintains accurate color rendition. * No setting required when using a digital single lens reflex camera. Adjust white balance on the camera, when color temperature needs adjusting. To change filters Pull the filter-changing ring towards the camera, rotate it, and set the desired filter setting on the filter index. Note Rotate the filter-changing ring until it clicks into place. If it is not set properly, a red line appears between the lens hood and filter-changing ring as a warning. . Exposure compensation When using a filter other than NORMAL, the amount of light reaching the image sensor (or the film) decreases. This is automatically compensated for in all auto- exposure modes, or in the manual exposure mode, providing that the exposure is adjusted according to the camera’s meter index. When shooting in manual mode using a hand-held exposure meter, increase exposure.
