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.
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. The focusing ring 
always works, regardless of the focus mode.
•  After autofocusing in ONE SHOT AF mode, focus manually by  pressing the shutter button halfway and turning the focusing 
ring (Full-time manual focus) 
 b.3. Infinity Compensation MarkTo 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 
 c.
•  For accurate focusing in MF on subjects at infinity distance, look  through the viewfinder while rotating the focusing ring.
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.
•  Some EOS cameras cannot use infrared film. See the instructions  for your EOS camera.
•  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.

5. FiltersYou can attach filters to the filter mounting thread on the front of 
the lens.
•	 Use	a	polarizing	Canon	filter.
Filter holder for the EF14mm f/2.8L USM
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 in\
to 
the filter holder 
❽.6. HoodThe	lens	hood	can	keep	unwanted	light	out	of	the	lens,	and	also	
protects	the	lens	from	rain,	snow,	and	dust.

and EF35mm f/1.4L USM
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	
❾.
EF85mm f/1.8 USM and EF100mm f/2 USM
Press the buttons on both sides of the hood to attach 
.

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. n
 
The lens length is measured from the mount surface to the front 
end	of	the	lens.	Add	21.5	mm	to	include	the	E-58U/E-72U	lens	
cap	and	dust	cap,	and	24.2	mm	for	the	E-58	II/E-72	II.
