Instructions

Thank you for purchasing a Canon product.

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.

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 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 (AF) mode, set the focus mode switch

to AF

❹

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

0.6-

: From closest focusing distance to infinity.

∞

: From 1 m to infinity.

3. Depth-of-Field Scale

The 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.

❻

• The depth-of-field scale is an approximate indicator.

4. Infrared Index

The 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

• 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.
