Safety Precautions
1.
Do not look at the sun or a bright light source through
the lens or camera.
Doing so could result in loss of vision.
Looking at the sun directly through the lens is especially
hazardous.
2.
Whether it is attached to the camera or not, do not leave
the lens under the sun without the lens cap attached.
This is to prevent the lens from concentrating the sun’s
rays, which could cause a fire.
Handling Cautions
If the lens is taken from a cold environment into a warm
one, condensation may develop on the lens surface and
internal parts.
To prevent condensation in this case, first
put the lens into an airtight plastic bag before taking it from
a cold to warm environment. Then take out the lens after it
has warmed gradually. Do the same when taking the lens
from a warm environment into a cold one.
1. Mounting and Detaching the Lens
See your camera’s instructions for details on mounting and
detaching the lens.
• After detaching the lens, place the lens with the rear end
up to prevent the lens surface and contacts from getting
scratched.
• If the contacts get soiled, scratched, or have fingerprints
on them, corrosion or faulty connections can result. The
camera and lens may not operate properly.
• If the contacts get soiled or have fingerprints on them,
clean them with a soft cloth.
• If you remove the lens, cover it with the dust cap. To attach
it properly, align the lens mount index and the
{
index of
the dust cap, and turn clockwise. To remove it, reverse the
order.
2. Setting the Focus Mode
To shoot in autofocus mode, set the focus mode switch to AF
❹
.
To use only manual focusing, set the focus mode switch to
MF, and focus by turning the focusing ring.
• Do not touch the focusing ring on the lens during
autofocusing.
3. Full-time Manual Focusing
Full-time manual focusing allows you to focus manually even
when autofocus mode is selected.
1) Set the camera to ONE SHOT AF mode and press the
shutter button halfway.
2) Keep the shutter button pressed halfway and turn the
focusing ring to focus manually
❺
.
4. Aperture Setting
Aperture settings are specified on the camera.
5. Infinity Distance Mark
To compensate for shifting of the infinity focus point that
results from changes in temperature.
The infinity position at normal temperature is the point
at which the vertical line of the L mark is aligned with the
distance indicator on the distance scale
❻
.
To make sure focus is precise, it is recommended that you
check the focus in the viewfinder before shooting.
6. Infrared Index
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
❼
.
Use a red filter also when you take the picture.
• Switch the focus mode to MF to turn the focusing ring for
adjustment.
• The position of the infrared indices is based on film usage
with a peak sensitivity of 800 nm and a red filter (such
as Wratten 87). Using black and white infrared film with
a different sensitivity may require a slightly different
setting. Thus, it is recommended to take trial shots with the
focusing ring set slightly to the left and then right of the
appropriate index to find the best position.
• Be sure to observe the manufacturer’s instructions when
using infrared film.
7. Filter (sold separately)
The filter screws onto the front of the lens.
• If you need a polarizing filter, use Canon’s PL-C polarizing
filter.
Filter holder for the EF14mm f/2.8L USM
This lens is constructed with a built-in, gelatin filter holder
in the rear
❽
. To insert, simply cut the filter to the same
dimensions (31 mm/1-1/4” × 31 mm/1-1/4”) as the white
brackets, then slide the filter into the holder.
