• 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.
