Look through the viewfinder, etc., and set the focus precisely. (50mm F2.8 Macro,100mm F2.8 Macro only) When focusing manually, set your camera to the manual focus and rotate the focusing ring while looking through the viewfinder, etc. Focus-hold button .–(2) While the focus-hold button is pressed, auto focus function is suspended and the focus is fixed for shooting. . The function of the focus-hold button can be changed on cameras with custom function capability. Refer to the camera manuals for details. Focus-range limiter .–(3) For quick focusing, the focusing range can be limited to close or far range, depending on the distance to your subject. Close-focusing range Far-focusing range 50mm F2.8 Macro Approx. 20 - 27cm Approx. 30cm - . 100mm F2.8 Macro Approx. 35 - 54cm Approx. 59cm - . To focus on subjects at close range (see the table above), set focus anywhere near the subject and then set the focus-range limiter to LIMIT; the focusing range is limited to Close-focusing range. Likewise, when shooting subjects at far range, set the focus anywhere near the subject and then set the focusrange limiter to LIMIT; the focus range is limited to Far-focusing range. Set the focus-range limiter to FULL to allow the entire focusing range. . Set the focus-range limiter to FULL, when shooting a subject between the Close and Far focusing ranges. 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. Macro lens depth of field (50mm F2.8 Macro, 100mm F2.8 Macro) Refer to the depth-of-field table . for details on depth of field. . The depth-of-field scale and depth-of-field table . is for 35mm-format cameras. The depth-of-field is shallower when you use Interchangeable Lens Digital Cameras equipped with an APS-C sized image sensor. . Macro photography (50mm F2.8 Macro, 100mm F2.8 Macro) Magnification ratios The magnification scale is located on the extending section of the lens barrel. The line on the magnification scale which the edge of the outer lens barrel overlaps indicates the current magnification ratio (1:1 in illustration .). . As the magnification increases, the camera is more vulnerable to shaking. Use a tripod to steady the camera when shooting. Precautions on using a commercially available exposure meter or manual flash shooting function The brightness of the lens decreases with macro shooting. This is automatically compensated for in all auto-exposure modes, or in metered manual mode. If your camera is set to the manual exposure mode and you are using a commercially available exposure meter, or if your camera is set to the manual exposure mode and you are using the Manual Flash Control function available on some external flash units, increase the exposure from the indicated value. (Refer to the Exposure compensation table . regarding the degree of compensation.) .
