●●The magnification of this lens is determined by 
the combination of the following three factors: 
the focusing ring position, zoom ring position, 
and focusing distance. Therefore, the number 
of combinations for achieving a certain level 
of magnification is countless. The method for 
close-up shooting described here involves trying 
as much as possible to keep the focus position 
within the range indicated by the yellow line on 
the distance scale. However, please keep in 
mind that this is...

7. Exposure during Close-up Shooting
●●The correct exposure for a close-up shot largely 
depends on the subject. Therefore, try to bracket 
the exposure for the same subject.
●● Using aperture-priority AE (Av) or Manual (M) 
picture-taking modes are recommended for 
macro photography as it is easy to adjust depth 
of field and exposure in these modes.
Setting the Exposure
When taking photographs using TTL metering, 
no exposure compensation is necessary to 
meter the light coming through the lens....

8.  Infinity Compensation 
Mark
For accurate manual focusing of subjects at infinity, 
look through the viewfinder or look at the magnified 
image* on the LCD screen while rotating the 
focusing ring.
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 distance 
scale L mark is aligned with the distance index.

10. Image Stabilizer
You can use the image stabilizer in AF or MF mode.This function provides optimal image stabilization depending on 
shooting conditions (such as shooting still subjects, following 
shots, and close-up shooting).

The image stabilizer in this lens is 
effective for hand-held shots under the 
following conditions.
●●Close-up shooting.
●● In semi-darkened areas such as 
indoors or outdoors at night.
●● In locations where flash 
photography is prohibited, such as 
art museums...

●●When shooting a still subject, it compensates for 
camera shake in all directions.
●● It compensates for vertical camera shake during 
following shots in a horizontal direction, and 
compensates for horizontal camera shake during 
following shots in a vertical direction.
●● When you use a tripod, the Image Stabilizer 
should be turned off to save battery power.
●● The stabilizer is equally effective for hand-
held photography and photography with a 
monopod. The Image Stabilizer effect may be...

The magnification refers to the ratio between the 
subject’s size and the corresponding image size on 
the focal plane.
11.  Image Stabilization during Close-up Shooting
For normal close-up shooting, the higher the 
magnification, the faster the shutter speed must 
be to prevent blur caused by camera shake. 
Although it depends on the shooting conditions, 
usually the shutter speed must be at least one 
or two stops faster than normal.

12.  Taking Hand-held Close-ups
Close-up shots are more prone to be affected by 
camera shake than with normal shooting. The 
Image Stabilizer’s corrective effect is therefore 
less during close-ups than during normal 
shooting even with the same degree of camera 
shake.
The depth of field also becomes very shallow 
with close-ups, and moving forward or back 
even slightly will throw off the focus.
When hand-holding the camera for close-up 
shooting, minimize camera shake and blurred 
focus with...

13. Hood
●Attaching
To attach the hood, align the hood’s attachment 
position mark with the red dot on the front of the 
lens, then turn the hood as shown by the arrow 
until the lens’ red dot is aligned with the hood’s 
stop position mark.●Removing
To remove the hood, hold down the button on 
the side and turn the hood in the direction of the 
arrow until the position mark on the hood aligns 
with the red dot. The hood can be reverse-
mounted on the lens for storage.
●●
If the hood is not...

You can attach extension tube EF12 II or EF25 
II for magnified shots. The shooting distance 
and magnification are shown below.
An extension tube cannot be used when the zoom 
ring is set to macro.
MF mode is recommended for accurate focusing.
