A special apodization element gives defocused areas a smooth and attractive appearance. This lens is equipped with the aperture ring that enables a stepless aperture setting between F No.2.8-5.7 (T No.4.5-6.7*), and makes the most of the defocusing effect in the foreground and background areas. Enjoy this unique image-expression, which cannot be duplicated on traditional lenses. * T No. (T-Numbers) : the T No. is a practical value that indicates how much light is in the lens, allowing for the lens's transmission rate. Although this lens's wide-open aperture is f/2.8, the special apodization system provides the light amount of T/4.5, which is the same as that of f/4.5 on a normal lens. The aperture value on the lens, the value indicated on a camera, and the value used when determining the exposure are all indicated by T No. Use the T No. as a normal aperture value. 5 98 76 Attaching/detaching the lens To attach the lens 1 Remove the rear and front lens caps and the camera body cap. · You can attach/detach the front lens cap in two ways, (1) and (2).

NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: ­ Reorient or relocate the receiving antenna. ­ Increase the separation between the equipment and receiver. 1 Select manual-focus mode on your camera. · Refer to the camera manual for details. · This lens can be used in manual-focus mode, even if your camera is set to autofocus mode. 2 Turn the focusing ring until the image appears sharp. · The focus signal found in the viewfinder does not work. Aperture This lens has two aperture settings; A position and a stepless aperture control. Use the aperture ring to switch between the two settings. T No. is used in both notation and control on the camera and lens. Stepless aperture range Exposure compensation As the magnification increases, the amount of light reaching the image sensor decreases. This is automatically compensated in all autoexposure modes, or in the manual exposure mode as long as the exposure is adjusted according to the camera's meter index. If your camera is set to the manual exposure mode and you are using a hand-held 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, adjust exposure accordingly. (E.g., when adjusting by the aperture, +1 means opening the aperture 1 more stop.) To use the stepless aperture setting This setting allows stepless control of the aperture between T/4.5 - T/6.7. Turn the aperture ring to set the desired aperture. · This stepless range is recommended when a large aperture is desired. · Set your camera to A mode or M mode when using this setting. (In P mode or sceneselection setting, the settings will be the same as A mode. In S mode, the settings will be the same as M mode.) · A slight click can be felt at the T/4.5, T/5.6, and T/6.7 marks. · The index marks between T/4.5 and T/5.6 represent 1/3 aperture values. · Stop-down metering is used when the stepless aperture is selected. · When shooting, the aperture values set by the aperture ring are used. Those values are not accurately reflected in the values displayed or recorded by the camera.

This special optical element is a type of ND filter which gradually becomes thicker (darker) towards the perimeter, thereby reducing the amount of light that passes through around the outer perimeter. The aperture of this lens is indicated and controlled by the T No., which compensates for the reduction imposed by the special apodization element. The T No. can be used as the F No. on a normal lens when the exposure is determined. To use the A position This setting (A position) allows the lens to be used the same way as traditional manual-focus lenses. Set the aperture on your camera. · All exposure modes (P, A, S, M) can be used on the camera. Aperture Information This lens has two apertures; the stepless aperture, manually controlled with the aperture ring, and the automatic aperture (A position), controlled by the camera. In the stepless aperture setting, emphasis is put on the aperture shape, which is rounder than the automatic aperture. For large aperture settings, selecting the stepless aperture is recommended. Stepless aperture Principle of defocusing effect improvement Defocusing of a dot Apodization element Defocusing of a line This lens Intensity decreases gradually toward the perimeter Gradually diffused without losing shape Automatic aperture (functioning when set to the A position) Theoretical ideal traditional lens Depth of field (in meters) 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. 10m 5m 3m 2m 1.5m 1.2m 1.0m 0.87m T/4.5 114.8 10.91 9.23 5.21 4.81 3.068 2.935 2.027 1.974 1.514 1.478 1.028 1.192 1.005 0.995 0.873 0.867 T/5.6 97.8 11.08 9.11 5.24 4.78 3.080 2.924 2.032 1.969 1.156 1.484 1.209 1.191 1.006 0.994 0.874 0.866 T/6.7 82.3 11.32 8.96 5.29 4.74 3.096 2.910 2.038 1.963 1.519 1.481 1.211 1.189 1.007 0.993 0.874 0.866 T/8 69.2 11.61 8.79 5.35 4.69 3.115 2.894 2.046 1.956 1.523 1.478 1.213 1.187 1.008 0.992 0.875 0.865 T/11 49.0 12.44 8.37 5.51 4.58 3.165 2.852 2.065 1.939 1.533 1.469 1.219 1.182 1.011 0.989 0.877 0.863 T/16 34.7 13.84 7.84 5.76 4.42 3.239 2.795 2.094 1.915 1.547 1.456 1.226 1.175 1.016 0.985 0.881 0.860 T/22 24.6 16.48 7.20 6.15 4.22 3.350 2.719 2.135 1.882 1.567 1.439 1.238 1.165 1.023 0.978 0.885 0.856 T/32 17.4 22.58 6.46 6.80 3.97 3.522 2.618 2.198 1.837 1.597 1.415 1.254 1.151 1.033 0.970 0.891 0.850 Intensity stays the same Line becomes thicker Defocused images appear as blurred clusters of dots. A lens with well compensated aberration reproduces the image shape accurately, but cannot produce smooth blurs in a defocused area. There may be unpleasant blurs, which for example, make one line appear to be doubled, depending on the way of compensation. This lens adopts a special apodization element that provides a gradually diffused image toward the perimeter without losing the core shape. In other words, it provides soft and natural defocusing without transforming the original shape unnaturally. 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.
