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

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

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.

•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.
