Thank you for purchasing a Canon product.
 Safety Precautions1. 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 CautionsIf 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.
Handling the EF50mm f/1.0L USM and EF85mm f/1.2L 
USM
The EF50mm f/1.0L USM and EF85mm f/1.2L USM are 
ultra-high-precision lenses. Take care not to subject them to 
shocks or impacts. Also ensure that the lenses are set to the 
“
¿” setting before putting them in the case.
1. Mounting and Detaching the LensSee 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 ModeTo shoot in autofocus (AF) mode, set the focus mode switch 
to AF  a.
To shoot in manual focus (MF) mode, set the focus mode 
switch to MF, and focus by turning the focusing ring.
Setting the Focusing Range (for EF50mm f/1.0L USM)
Two autofocus ranges are selectable with the lens 
 b.
0.6-¿: From closest focusing distance to infinity.
1-¿: From 1 m to infinity.
3. Depth-of-Field ScaleThe depth of field is the distance in front of and behind the 
plane of focus on the subject that appears sharp. The depth 
of field is indicated by the area between the depth-of-field 
scale lines below the distance scale. The numbers on the 
scale are F values, and for example, if the shooting distance 
is 1.5 m/5 ft. and the aperture is f/11 with the EF35mm 
f/2, the sharp area will extend from about 1.2 m/4 ft. to 2.8 
m/9.3 ft. 
 c.
•  The depth-of-field scale is an approximate indicator.
4. Infrared IndexThe 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 
 d.
•  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.

Ô )5. HoodThe lens hood can keep unwanted light out of the lens, and 
also protects the lens from rain, snow, and dust.
EF24mm f/2.8
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 in the direction of the arrow until the lens’s red dot is 
aligned with the hood’s stop position mark

Press the buttons on both sides of the hood to attach 
 e.
The hood can be reverse-mounted on the lens for storage.
•  Part of the picture may be blocked if the hood is not  attached properly.
•  When attaching or detaching the hood, grasp the base of  the hood to turn it. To prevent deformation, do not grasp 
the rim of the hood to turn it.
6. FiltersYou can attach filters to the filter mounting thread on the 
front of the lens ).
•  Only one filter may be attached.
•  Use a polarizing Canon filter.
Filter Holder for the EF15mm f/2.8 Fish-eye
There is a gelatin filter holder at the rear of the lens 
). Cut 
the gelatin filter to fit within the white frames. Then insert 
the gelatin filter into the filter holder. Q
  The lens length is measured from the mount surface to 
the front end of the lens. Add 21.5 mm when including 
the lens cap and dust cap. (Add 16.8 mm for EF15mm 
f/2.8 Fish-eye)
