light sources through a lens. This may result in

loss of sight.

z Do not leave a lens in the sun without the lens

cap attached. The lens may concentrate entering

sunlight and cause a malfunction or fire.

General PrecautionsGeneral Precautions

Handling Precautions

z Do not leave the product in excessive heat such as

in a car in direct sunlight. High temperatures can

cause the product to malfunction.

z 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.

z Please also read any lens related handling

precautions listed in your camera’s instruction

manual.

Attaching the Lens

Align the lens mount indexes of the lens and

camera, and turn the lens clockwise until you

hear a click.

Detaching the Lens

Turn the lens counterclockwise while pressing

the camera’s lens release button. Detach the

lens once it has stopped turning.

Please refer to the camera's instructions for

details.

zSet the camera’s power switch to OFF when

attaching or detaching the lens.

zAttach the lens cap before detaching the lens

from the camera.

zAfter detaching the lens, place the lens with the

rear end up and attach the dust cap to prevent

the lens surface and contacts from getting

scratched. Make sure the lens and dust cap

mount indexes are aligned when attaching the

dust cap.

zContacts that are scratched, soiled, or have

fingerprints on them may result in faulty

connections or corrosion, which may lead to

malfunctions. If the contacts get soiled, clean

them with a soft cloth.

zThe lens mount has a rubber ring to improve

dust-resistance and water-resistance

performance. This rubber ring may cause

friction marks to appear around the camera’s

lens mount, although this will have no effect on

usage.

zRubber rings can be replaced at Canon Service

Center. (chargeable)

ENG-7

Focus mode switch

Focusing ring

To shoot in autofocus (AF) mode, set the focus

mode switch to AF.

To use only manual focusing (MF), set the focus

mode switch to MF, and focus by turning the

focusing ring.

2. Setting the Focus Mode

z Quickly turning the focusing ring may result in

delayed focus.

zThe lens’ focusing ring is electronic.

zWhen AF operation is set to [ONE SHOT],

manual focus is possible after autofocusing

has been completed by continuing to press the

shutter button halfway. (Full-time manual focus)

However, the camera settings need to be

changed.

ENG-8

The control ring can be assigned the functions

that are commonly used with cameras, such as

shutter speed and aperture settings.

Control ring

The click action of the control ring allows you to

have a sense of how much it is being turned.

Please refer to the camera's instructions for

details on how to use the control ring.

z There are cases in which the sound of control

ring operations may be recorded when shooting

movies.

zThe clicking sensation of the control ring can

be removed by the Canon Service Center.

You can set the focusing distance range with a

switch. By setting a suitable focusing distance

range, the actual autofocusing time will be

shorter.

The custom lens hood cuts out unwanted light and protects the front of the lens from rain, snow, and

dust.

●Attaching the Hood

Align the red attachment position mark on the

hood with the red dot on the front of the lens,

and then turn the hood in the direction of the

arrow until you hear a click.

Button

●Detaching the Hood

Keep your finger pressed down on the button

located on the side of the hood, and then turn

the hood in the direction of the arrow until the

attachment position mark on the hood is aligned

with the red dot on the front of the lens to detach it.

The hood can be reverse-mounted on the lens

for storage.

z If the hood is not attached properly, vignetting (darkening of the perimeter of the picture) may occur.

z Grasp and turn the base of the hood when attaching and detaching it. There are cases in which it may

become deformed if the hood is turned with it grasped near to the rim.

ENG-10

z In addition to being equipped with the same optical system found in the RF85mm F1.2 L USM, the

RF85mm F1.2 L USM DS is a shooting lens that features DS coating.

DS coating gradually reduces light transmission (obstructs light) from the center of the lens

outward.

The DS (Defocus Smoothing) effect which results in a soft, unique bokeh is created by controlling

the amount of light that passes through the lens, smoothing the edges of out-of-focus areas.

Without DS coating With DS coating

Comparison of lens with and without DS coating and resulting out-of-focus areas

z The DS effect (visual impact of softer-edged, out-of-focus highlights) is strong when the DS lens is shot

wide-open and diminishes as the DS lens’ aperture is stopped down.

6. DS Coating and DS Effect

ENG-11

z Since this lens utilizes DS coating which reduces light transmission (obstructs light), the brightness

level when the lens is shot wide-open is lower than what is expected when at f/1.2.

However, the aperture value displayed by the camera will be displayed as usual using the

applicable f-number.

z AE shooting can be performed as usual. However, when deciding the exposure using a hand-held

exposure meter, use the following table as a guide and apply the exposure factor using ISO speed

or shutter speed before shooting.

It is therefore recommended that you change the exposure level as much as possible during

shooting, or that you take pictures while checking the captured images.

DS Coating and DS Effect

z Other Shooting Precautions

• Compared to the RF85mm F1.2 L USM, the effect for improving loss of light around the edge of

the lens is diminished even when the lens is set to its lowest aperture.

(not applicable when Peripheral Illumination Correction is used)

• Since the amount of bokeh is less than that offered by the RF85mm F1.2 L USM lens, depth-of-

field will appear deeper in shots taken with the DS lens.

• If you look inside the lens from the front, the surface with DS coating will appear iridescent or

you may see a round pattern in the center. However, these factors do not have any negative

impact on shooting.

ENG-13

7. Filters (Sold separately)

You can attach filters to the filter mounting thread

on the front of the lens.

z Only one filter may be attached.

zIf you need a polarizing filter, use the Canon

Circular Polarizing Filter PL-C B.

zDetach the hood when adjusting the polarizing

filter.
