The ES-68 hood can keep unwanted light out of the lens, and also protects the 

lens from rain, snow, and dust.

on the front of the lens, then turn the hood in the direction of the arrow 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.

 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. To prevent deformation, do not grasp the rim of the hood to turn 

it.

●

 If the lens is attached to the camera with the hood reverse-mounted, 

remove the hood before removing the lens from the camera.

You can attach filters to the filter mounting thread (ø49 mm) on the front of the 

lens.

Only one filter may be attached.

You can attach extension tube EF12 II or EF25 II for magnified shots. For 

shooting distance and magnification, see the extension tube specifications.

MF mode is recommended for accurate focusing.

 The extenders cannot be used with this lens.

 The close-up lenses cannot be used with this lens. (The end of the lens will 

become heavy, causing the focus to become unstable.)
