The EW-54 hood cuts out unwanted light and 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 as shown 

by the arrow until the lens’ red dot is aligned with the hood’s stop 

position mark. (fig.❺)

The hood can be reverse-mounted on the lens for storage.

•

If the hood is not attached properly, vignetting (darkening of 

the perimeter of the picture) may occur.

•

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.

You can attach filters to the filter mounting thread on the front of 

the lens.

Only one filter may be attached.
