    8.Infinity Compensation Mark
    To compensate for shifting of the infinity focus
    point that results from changes in temperature,
    y ou can rotate the distance scale slightly past
    the normal infinity focus mark.
    • The infinity position at normal temperature is the point
    at which the vertical line of the  mark is aligned
    with the distance indicator.
    •F or accurate manual focusing on subjects at infinity
    distance, look through the viewfinder to confirm
    f ocusing while rotating the focusing ring.
    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.
    The compensation amount differs depending on the
    focal length. Use the indicated focal length as a
    guide when setting the compensation amount.
    • The infrared index position is based on a
    wa velength of 800 nm.
    • Be sure to observe the manufacturer’s
    instructions when using infrared film.
    • Use a red filter when you take the picture.
    9. Infrared Index
    Some EOS cameras cannot use infrared film. See
    the instructions for your EOS camera.  
    10. Using the Tripod Mount
    Adjusting the Tripod Mount
    Loosening the orientation locking knob on the tripod mount allows you to turn the lens and camera freely.
    This is useful when you want to switch the camera between horizontal and vertical positions while it is
    mounted on a tripod. Once you have set the camera to the desired position, tighten the locking knob firmly.
    Detaching the Tripod Mount
    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.
    Turn the tripod collar to align
    the red dots on the collar
    and lens.
    Slide off the tripod collar
    aw ay from the rear of the
    11. Hood
    The ET-86 hood can keep unwanted light out of the lens,
    and also protects the front of the lens from rain, snow,
    and dust.
    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 clockwise until the lens’s red dot is aligned with
    the hood’s stop position mark.
    The hood can be reverse-mounted on the lens for storage.
    •P art of the picture may be blocked if the hood is
    not attached properly.
    •T o attach (remove) the hood, grasp the base of
    the hood and turn it clockwise
    (counterclockwise). Do not hold the hood by the
    outer rim as this could result in the hood being
    distorted if too much pressure is applied.
    Y ou can attach filters to the filter mounting thread
    on the front of the lens.
    • If you need a polarizing filter, use Canon’s 
    PL-C 77 mm ll polarizing filter. Note that you must
    remove the hood before adjusting the polarizing filter.
    • When the PL-C 77mm ll polarizing filter is attached,
    the lens cap cannot be attached.
    12. Filters (Optional)
    With Extension Tube EF 12 ll or EF 25 ll, the
    camera-to-subject distance and image
    magnification will be as follows:
    13.Extension Tubes(Optional)
    Camera-to-SubjectMagnificationDistance (mm)Near Far Near Far
    EF12 ll 70mm 550 624 0.22
    200mm 1110 3401 0.24 ×0.06×
    EF25 ll 70mm 402 407 0.41
    200mm 929 1737 0.32 ×0.14×  
    •AF is possible with Extender.
    • When an Extender is attached, the AF speed will become slower by design to retain proper
    AF control.
    •Do not attach more than one Extender on the same lens. Having more than one Extender on
    the lens will degrade the optical performance and cause exposure errors by the cameras
    built-in exposure metering.
    • If you use an Extender on the lens mounted on a EOS A2/A2E/5, set the exposure
    compensation to -1/2 stop for the EF 1.4X ll or -1 stop for the EF 2X ll.
