EF8-15mm f/4L Fisheye USM C Y P O ENG Instruction
Thank you for purchasing a Canon product. The Canon EF8-15mm f/4L Fisheye USM lens is a high-performance fisheye zoom lens designed for use with Canon EOS cameras. Features 1. Designed for use with three different image sensor sizes. 2. Aspherical and UD lens elements result in outstanding image delineation. 3. SWC (Subwavelength Structure Coating) is utilized to significantly reduce occurrences of flare and ghost created by quite large incident angles of light. 4.
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.
Precautions for Shooting with a Fisheye Lens • If dirt or dust adheres to the surface of the front lens element, it can easily appear in images due to the lens’s short focal length. In order to avoid this, please remove dirt or dust from the surface of the front lens element by using a commercially available air dust blower. • Since this lens has an extremely wide angle of view, light from bright light sources, such as the sun, can easily enter the image area.

1. Mounting and Detaching the Lens See your camera’s instructions for instructions on mounting and detaching the lens. The lens mount has a rubber ring for enhanced water- and dust-resistance. The rubber ring may cause slight abrasions around the camera's lens mount, but this will not cause any problems. If the rubber ring becomes worn, it is replaceable by a Canon Service Center at cost.
2. Setting the Focus Mode 3. Zooming Y P O 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. The focusing ring always works, regardless of the focus mode. C To zoom, turn the zoom ring. Be sure to finish zooming before focusing. Changing the zoom ring after focusing can affect the focus.
Zooming “C” and “H” Markings Y P O Zoom Limiter Adjacent to the zoom ring, the “C” and “H” markings serve as guides to indicate the wideangle zoom position where focus is set at infinity at which photos can be created without vignetting when using EOS digital cameras installed with APS-C or APS-H image sensors. The “C”/”H” indicator on the zoom ring is aligned with either the “C” or “H” marking.
Zooming Description of Fisheye Lens Based Photography The various images below show the different relationships between the fisheye lens’s 180 degree angle of view and the size of each image sensor related to focal length. Approx. 15mm Focal Length: 8mm Approx. 10mm Full Frame Circular Fisheye APS-C Diagonal Fisheye Approx. 12mm Y P O APS-H Diagonal Fisheye * The circle corresponding with each focal length indicates a 180 degree angle of view in the imaging area.
4. Infinity Compensation Mark 5. Infrared Index 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.
6. Hood The EW-77 hood can keep unwanted light out of the lens, and also protects the front of the lens from rain, snow, and dust. Attaching C Y P O To attach the hood, align the hood’s attachment position mark with the red dot on the front of the lens, then turn the hood as shown by the arrow until the lens' red dot is aligned with the hood's stop position mark.
Hood Vignetting will not occur while shooting in the following zoom ranges when using the lens hood. Please detach the lens hood when shooting outside of these ranges. • Full Format: Only at the telephoto end • APS-H: From the telephoto end to the “H” marking • APS-C: From the telephoto end to the “C” marking (range when using the zoom limiter) • Part of the picture may be blocked if the hood is not attached properly. • When attaching or detaching the hood, grasp the base of the hood to turn it.
7. Lens Cap 8. Filter Recessed Section Y P O While the lens hood (included) is attached to the lens, Lens Cap 8-15 can be attached to the lens hood by pressing the buttons located on the upper and lower sides of the lens cap and aligning its recessed parts with the convex parts found in the lens hood. C (Sold separately) There is a gelatin filter holder at the rear of the lens. Cut the gelatin filter to fit within the white frames. Then insert the gelatin filter into the filter holder.
