Macro Operation
With this lens, you can focus down to 0.3 meters (11.8 in.) at the 35mm focal length setting for a maximum 1:3.8 magnification ratio. First, set the operating ring to the f=35mm setting and turn the ring to 1 .6m minimum object distance setting. Pull the operating ring further and it will shift slightly. Then, rotate the ring so that the MACRO marks on the operating ring and the lens barrel meet together. Push the operating ring forward towards the object and you can see macro magnification scales, which show the macro magnification ratios at each setting. In this operation, the object distance can be changed steplessly from 1.6m to O.3m so that image interruption should not occur. When you want to return to the normal mode after macro operation, pull the operating ring towards the camera body and rotate it counter-clockwise.
You can zoom when the operating ring goes past 1.6m, the minimum object distance in the normal mode. In macro photography, the operating ring will only shift forwards or backwards.


Aperture Control
Rotate the aperture control ring and set the required aperture against the index line. In fact, there are two aperture indexes, because the maximum aperture of this lens changes at the wideangle and telephoto ends. Set the desired f-stop to the blue line at the wideangle position (f=35mm) or to the orange line at the telephoto position (f=210mm). Intermediate click stops are provided from F/3.5 to F116 for precise exposure control.


AE-Setting
When using your lens on cameras which incorporate a shutter priority automatic mode, turn the aperture control ring on your lens to the AE position which also serves F/32 when the lens is used on other cameras.


Infra-Red Index
Since the focal point shifts in infra-red photography, it is necessary to correct the focus. Focus in the normal manner, set an infra-red filter and shift the indicated distance to the red line marked "R".


Notes: Shooting with an electronic flash
This lens features a variable aperture design, with the maximum aperture changing about a half stop between the wideangle and telephoto ends of the zoom range (F/3.5-4.2). When you shoot in the normal mode using a TTL light metering mode, the aperture will automatically be adjusted to the amount of the incident light. When shooting with an electronic flash, adjust the aperture by following the procedure below.
1. Set the f-stop (obtained from the guide number of the flash) to the blue aperture index line at the 35mm wideangle end or the orange aperture index line at the 2lOmm telephoto end.
2. When you shoot at an intermediate focal Iength setting or while zooming, set the f-stop obtained from the guide number in the middle of the two index lines.
3. When shooting with the type of auto flash that controls the f-stop with a signal from the camera, use the flash in a manual mode.
4. When shooting with cameras that control the exposure during exposure itself, no adjustment is needed.
