EF180mm f/3.
Thank you for purchasing a Canon product. The Canon EF180mm f/3.5L MACRO USM lens is a high-performance telephoto macro lens for EOS cameras that can be used for normal photography and close-up pictures up to 1:1, or life-size, magnification. • "USM" stands for Ultrasonic Motor. C Features 1. The floating system and UD element result in excellent delineation at all focusing distances from life-size to infinity. 2. Ultrasonic motor (USM) for quick and quiet autofocusing. 3.
a Safety Precautions a Safety Precautions • 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. • 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 C This device complies with Part 15 of the FCC Rules.

1. Mounting and Detaching the Lens 2. Setting the Focus Mode See your camera’s instructions for details on mounting and detaching the lens. Y P O • After detaching the lens, place the lens with the rear end up to prevent the lens surface and electrical 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.
3. Switching the Focusing Distance Range 4. Hood Y P O You can set the focusing distance range to 0.48 m/1.6 ft. to infinity or 1.5 m/4.9 ft. to infinity. By setting the suitable focusing distance range, the actual autofocusing time can be shorter. C If you autofocus outside the set focusing distance range, the lens may stop focusing at the start of the focusing range; however, this is not a malfunction. Press the shutter release button halfway again.
5. Infinity Compensation Mark 6. Depth-of-Field Scale Infinity compensation mark Distance index Y P O 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. C For accurate manual focusing on subjects at infinity distance, look through the viewfinder while rotating the focusing ring.
7. Picture Taking 3. Focus the subject. While looking through the viewfinder, move the camera forward or back to find the point of focus. 4. Touch up the focus. Turn the focusing ring for fine focusing. Normal Photography The lens can be used as a telephoto lens for normal photography. Closeup Photography Close-up photos (minimum focusing distance of 0.48m) up to 1x (life-size) magnification are possible. The minimum focusing distance is the distance from the subject to the film plane.
8. About Exposure Setting the Exposure When taking photographs using TTL metering, no exposure compensation is necessary to meter the light coming through the lens. With TTL metering, AE (autoexposure) is possible at all focusing distances. Just set the desired picture-taking mode, then check the shutter speed and aperture before taking the picture. Magnification and Effective f-number 1:10 1:5 1:3 Effective f/No. 3.8 4 4.
9. Macro Flash (Sold Separately) The Canon Macro Ring Lite MR-14EX or the Macro Twin Lite MT-24EX enables fully automatic macro flash photography up to 1x magnification in E-TTL autoflash mode. Install the Macro Lite Adapter 72C (sold separately) on the filter mounting thread on the front of the lens for macro flash photography. C For normal photography, remove the Macro Lite Adapter, because it may create a dark circumference.
10. Using the Tripod Mount Adjusting the Revolving Mount You can loosen the orientation lock-knob on the tripod mount to allow it to rotate as needed to fit a particular camera model for switching between vertical and horizontal positions. Detaching First remove the lens from the camera and then remove the tripod mount from the lens as shown below. To attach the tripod mount, reverse the procedure. Loosen the orientation locking knob.
11. Filters 12. Extension Tubes (Sold separately) (Sold separately) You can attach filters to the filter mounting thread on the front of the lens. • If you need a polarizing filter, use the Canon Circular Polarizing Filter (72mm). • To adjust the polarizing filter, first remove the lens hood. You can attach Extension Tube EF12 II or EF25 II for magnified shots. The shooting distance and magnification are shown below.
. Extenders (Sold separately) With Extender EF1.4X ll or EF2X ll attached, the lens specifications will change as follows: Item With EF1.4X ll Extender Focal length (mm) Aperture Angle of view With EF2X ll Extender 252 360 in 1 3 stops f/5 – 45 f/7.1 – 64 in 1 2 stops f/4.5 – 45 f/6.7 – 64 Diagonal 9°50’ 6°50’ Vertical 5°30’ 3°50’ Horizontal 8°10’ 5°40’ 1.4 2.0 Maximum magnification (×) C Y P O • First attach the Extender to the lens, then attach the lens to the camera.
. Close-up Lenses (Sold separately) Attaching a 500D (72mm) Close-up Lens enables close-up photography. Magnification will be 1.48× – 0.36×. • Close-up Lens 250D cannot be attached because there is no size that fits the lens. • Manual focusing is recommended for accurate focusing.
