ENG-10 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.
ENG-11 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 lens.
ENG-12 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 ×0.17× 200mm 1110 3401 0.24 ×0.06× EF25 ll 70mm 402 407 0.41 ×0.38× 200mm 929 1737 0.32 ×0.14×
ENG-13 •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. 14.
