1. Mounting and Detaching the Lens See your camera’s instructions for details on mounting and detaching the lens. ● After detaching the lens, place the lens with the rear end up to prevent the lens surface and contacts from getting scratched. ●...
3. Switching the Focusing Distance Range You can set the focusing distance range to 1.8 m/5.9 ft. to infinity or 6.5 m/21.3 ft. to infinity. By setting the suitable focusing distance range, the actual autofocusing time will be shorter. If you use AF from outside the specified focusing distance range, the lens may stop focusing when it reaches the limit of the range.
4. Adjusting Zooming Resistance Move the zoom ring forward or backward to zoom. ● Be sure to finish zooming before focusing. Changing the zoom ring after focusing can affect the focus. ● To prevent unintended extension of the front of the lens, be careful not to set the zoom ring too loose.
5. Image Stabilizer You can use the image stabilizer in AF or MF mode. STABILIZER Set the STABILIZER switch to ON. ● If you are not going to use the image stabilizer function, set the switch to OFF. STABILIZER MODE STABILIZER Select the stabilizer mode.
6. Tips on Using the Image Stabilizer The image stabilizer in this lens is effective for hand-held shots under the following conditions. ● MODE 1 ● In semi-darkened areas such as indoors or outdoors at night. ● In locations where flash photography is prohibited, such as art museums and theater stages.
Tips on Using the Image Stabilizer ● The Image Stabilizer cannot compensate for a blurred shot caused by a subject that moved. ● Set the STABILIZER switch to OFF when using the camera on a tripod. If the switch is set to ON, the Image Stabilizer may introduce errors.
7. Infinity Compensation Mark Infinity compensation mark Distance index To compensate for shifting of the infinity focus point that results from changes in temperature. The infinity position at normal temperature is the point at which the vertical line of the L mark is aligned with the distance indicator on the distance scale.
9. Using the Tripod Mount Adjusting the Tripod Mount By loosening the orientation locking knob on the tripod mount you can rotate the camera to set the image for any vertical or horizontal position. Detaching the Tripod Mount First remove the lens from the camera and then remove the tripod mount from the lens as shown below.
