1. Do not look at the sun or a bright light source through 

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 

 

This is to prevent the lens from concentrating the sun’s 

rays, which could cause a fire.

 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.

•  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.

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.

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

.

Aperture settings are specified on the camera.

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.

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.

The filter screws onto the front of the lens.

•  If you need a polarizing filter, use Canon’s PL-C polarizing 

filter.

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.
