5. Picture Taking

Normal Photography

The lens can be used as a medium-telephoto lens for normal photography such as portraits.

Closeup Photography

Close-up photos up to 1x (life-size) magnification are possible. The minimum focusing distance of

31 cm is the distance from the subject to the focal plane. The working distance from the front of the lens to the subject is about 15 cm.

When focusing, you can give priority to framing or to magnification.

the subject, focus with the AF or MF mode.

[Magnification Priority]

1. Set the lens' focus mode switch to MF.

2. Set the magnification.

While referring to the magnification scale on the lens, turn the focusing ring to the desired magnification.

3. Focus the subject.

While looking through the viewfinder, move the camera forward or back to find the point of focus.

4. Touch up the focus.

Turn the focusing ring for fine focusing.

Since macro shots have a very shallow depth of field, focus carefully to obtain proper sharpness.

6. About Exposure

Setting the Exposure

When taking photographs using TTL metering, no exposure compensation is necessary to meter

When you use a handheld exposure meter to set the exposure, you must take into account the exposure factor shown in the following table.

If your eye will not be covering the eyepiece when the picture is taken (with remote control operation, etc.), use the eyepiece shutter or eyepiece cover.

This prevents stray light from entering the eyepiece and throwing off the proper exposure.

• If the EOS camera has a built-in flash, the pentaprism may prevent the tripod mount from being rotated to the top of the lens.

ENG-8

Using the Tripod Mount (Sold separately)

Attaching and Detaching the Tripod Mount

To attach the tripod mount, follow the illustrated procedure below. To remove the tripod mount, follow the procedure in reverse.

Loosen the tripod mount’s COP mount’s index, and slip on the tripod mount.

Y

Align the tripod mount adapter's index with the lens mount index. Push in the adapter onto the back of the lens.

• The tripod mount adapter's inner lugs should slide into the grooves on the lens barrel.

The adapter should not be able to rotate around the lens barrel.

Rotate the tripod mount to the desired position and tighten the lock knob.

• You can loosen the orientation lock-knob on the tripod mount to allow it to rotate as needed to fit a particular camera model for switching between vertical and horizontal positions.

Depending on the EOS camera model, if a battery pack or vertical grip is attached, the tripod mount may bump into it. If that is the case, remove the battery pack/vertical grip or the tripod mount.
