The infrared index corrects the focus setting when using

monochrome infrared film. Focus on the subject

manually, then adjust the distance setting by moving the

focusing ring to the corresponding infrared index mark.

• The compensation amount differs depending on the

focal length. Use the indicated focal length as a

guide when setting the compensation amount.

Some EOS cameras cannot use infrared film. See

the instructions for your EOS camera.

[l] •

The infrared index position is based on a

wavelength of 800 nm.

• Be sure to observe the manufacturer's

instructions when using infrared film.

• Use a red filter also when you take the picture.

The EW-83E hood can keep unwanted light out of the

lens, and also protects the front of the lens from rain,

snow, and dust.

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 clockwise until the lens's red dot is

aligned with the hood's stop position mark.

The hood can be reverse-mounted on the lens for storage.

o ·

Part of the picture may be blocked if the hood is

not attached properly.

• To attach (remove) the hood, grasp the base of

the hood and turn it clockwise

(counterclockwise). Do not hold the hood by the

outer rim as this could result in the hood being

distorted if too much pressure is applied.
