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 Precautions for EF50mm f/1.0L USM and EF85mm f/1.2L USM

• Handle these lenses of precision with care and protect it from sudden shock and abusive handling.
• Before putting the lens in its case, put the lens hood on the dust cap and set the lens to the ” ” position.

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 auto focus mode, set the focus mode switch to AF . To use only manual focusing, set the focus mode switch to MF (M), 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.
• 1- : From 1m 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. Numbers in the scale are in F values, and for example, if the shooting distance is 1.5m and the aperture is f/11 with the EF35mm f/2, the sharp area will extend from about 1.2m to 2.8m .

• 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 manually, then adjust the distance setting by moving the focusing ring to the corresponding infrared index mark . Use a red filter also when you take the picture. · Switch the focus mode to MF (M) 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).
• Be sure to observe the manufacturer’s instructions when using infrared film.

5. Hood EF15mm f/2.8 Fish-eye (built-in) EF24mm f/2.8, EF28mm f/2.8, EF35mm f/2, EF50mm f/1.8 (sold separately) EF50mm f/1.0L USM, EF85mm f/1.2L USM (supplied with the lens) Be sure to use the hood to keep stray light out for best results with the EF50mm f/1.0L USM and the EF85mm f/1.2L USM. Attach the lens hood as illustrated.

• The EF15mm f/2.8 Fish-eye hood is built-in.
• To mount the hood on the EF24mm f/2.8 lens, align the hood’s attachment position mark with the red dot on the front of the lens, then turn the hood clockwise until the lens’s red dot is aligned with the hood’s stop position mark.

6. Filter (sold separately) The filter screws onto the front of the lens .

• Only one filter may be attached.
• If you need a polarizing filter, use Canon’s PL-C polarizing filter.

Filter holder for the EF15mm f/2.8 Fish-eye
This lens is constructed with a built-in, gelatin filter holder in the rear . To insert, simply cut the filter to the same dimensions (31mm (1-1/4″) × 31mm (1-1/4″)) as the white brackets, then slide the filter into the holder. EOS-1 usage: When using the EF50mm f/1.0L USM, the corners of the picture area experience a slight darkening. This will not affect the picture.

• The lens length is measured from the mount surface to the front end of the lens. Add 21.5mm when including the lens cap and dust cap. (Add 16.8mm for EF15mm f/2.8 Fish-eye)
• The size and weight listed are for the lens only, except as indicated.
• Product specifications and appearance are subject to change without notice.
