Attaching and Detaching a Lens

About Zooming

To zoom, turn the zoom ring on the lens with your fingers.

If you want to zoom, do it before focusing. Turning the zoom ring after achieving focus may throw off the focus slightly.

Detaching the Lens

While pressing the lens release button, turn the lens as shown by the arrow.

Turn the lens until it stops, then detach it.

Attach the dust cap to the detached lens.

Attaching a Hood

When the dedicated EW-83H hood is attached to the EF24-105mm f/4L IS USM lens, it can block unwanted light and also protect the front of the lens from rain, snow, dust, etc. When storing the lens in a bag, etc., you can also attach the hood in reverse.

1 Align the hood’s red mark with

the red index on the lens edge.

2 Turn the hood to the position shown in the illustration.

Turn the hood clockwise to attach it securely.

If the hood is not properly attached, the image periphery might look dark. When attaching or detaching the hood, grasp the hood toward the bottom to turn it. If you hold the front edge of the hood, it might get bent out of shape and become unable to turn.
