Thank you for purchasing a Canon product. The Canon EF-S55-250mm f/4-5.6 IS STM is a high-performance telephoto zoom lens that makes movie shooting comfortable. The lens is equipped with an Image Stabilizer and has been developed for EOS cameras compatible with EF-S lenses*.
Safety Precautions 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. ●● Do not leave the lens in excessive heat such as in a car in direct sunlight.
Safety Precautions This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Do not make any changes or modifications to the equipment unless otherwise specified in the instructions. If such changes or modifications should be made, you could be required to stop operation of the equipment.
Shooting Precautions The EF-S55-250mm f/4-5.6 IS STM utilizes a stepping motor that drives the focus lens. The motor also controls the focus lens during zooming. 1. When the camera is OFF The motor does not operate while the camera is OFF or when the camera is OFF due to the use of the auto power off function. Therefore, users must be aware of the following points. ●● Manual focus adjustments are not possible. ●● During zooming, delayed focus will occur. 2.

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 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 4 Zooming To zoom, turn the lens’ zoom ring. The ET-63 hood cuts out unwanted light and protects the front of the lens from rain, snow, and dust. Turn the hood in the direction of the arrow to attach it securely. The hood can be reverse-mounted on the lens for storage. Y P O ●● Be sure to finish zooming before focusing. Zooming after focusing can affect the focus. ●● Blurring may temporarily occur if the zoom ring is quickly rotated. ●● Zooming when the camera is OFF will result in delayed focus.
5 Image Stabilizer You can use the image stabilizer in AF or MF mode. This function provides optimal image stabilization depending on shooting conditions (such as shooting still subjects and following shots). 1 Set the STABILIZER switch to ON. C Y P O ●● If you are not going to use the image stabilizer function, set the switch to OFF. 2 When you press the shutter button halfway, the Image Stabilizer will start operating.
Image Stabilizer The image stabilizer for this lens is effective for hand-held shots in the following conditions. Y P O ON ON C OFF ●●In semi-darkened areas such as indoors or outdoors at night. ●●In locations where flash photography is prohibited, such as art museums and theater stages. ●●In situations where your footing is uncertain. ●●In situations where fast shutter settings cannot be used. OFF ●●When panning subjects in motion.
6 Filters (sold separately) 7 You can attach filters to the filter mounting thread on the front of the lens. ●● Only one filter may be attached. ●● If you need a polarizing filter, use the Canon Circular Polarizing Filter PL-C B (58 mm). ●● To adjust the polarizing filter, first remove the lens hood. C Extension Tubes (Sold Separately) You can attach extension tube EF12 II or EF25 II for magnified shots. The shooting distance and magnification are shown below.
8 Close-up Lenses (Sold separately) Attaching a 250D or 500D (58mm) Close-up Lens enables close-up photography. The magnification will be as follows. ●● Close-up Lens 250D: 0.23x - 1.04x ●● Close-up Lens 500D: 0.11x - 0.66x MF mode is recommended for accurate focusing.
