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
, .
• 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.
