6. Infrared Index

The infrared index corrects the focus setting when using

monochrome infrared film.

Focus on the subject in MF, then adjust the distance setting by

moving the focusing ring to the corresponding infrared index mark

❼

• 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.

7. Filters (Sold Separately)

You can attach filters to the filter mounting thread on the front of

the lens.

• Use a polarizing Canon filter (52 mm).

8. Getting Better Results with Soft Focus

(1) Lighting

In general, soft focus gives better results in backlit or semi-backlit

shots. It is also a good idea to use a lens hood to avoid unwanted

effects from extraneous light in the shot.

(2) Subject foreground and background

In normal soft focus shots, you get a better result if you select

something relatively dark as the background for your subject.

Also, shot compositions that involve defocusing the foreground

are not a good idea as the defocusing effect is poor.

(3) Shooting distance

This lens gives its best soft focus effect at distances between 3

and 5 meters.

(4) Exposure

In general, exposures that are slightly higher than the correct

exposure produce a better soft-focus effect.
