Drop-In Filters

A 52(WII)-series drop-in gelatin filter holder with a glass filter is included with the lens. The drop-in filter holder can be used fitted with a gelatin filter (sold separately).


<Installing and Removing>
To remove the drop-in filter, press in the left and right lock buttons and pull the filter holder straight up out of the slot.

To install the drop-in filter, push the filter holder straight down into the slot until it clicks into place.

• The filter holder can be installed facing either forwards or backwards.

Because the lens optics are designed to include a glass filter, you must always install the filter holder, even if no gelatin filter is fitted.

<Using a Gelatin Filter>

	Lift up the holder's retaining plate.
	Cut the gelatin filter as shown and mount it in the holder.
	Return the retaining plate to its closed position.
	The Drop-In Screw-Type Filter Holder 52(WII) and Drop-In Circular Polarizing Filter PL-C52(WII) are also available (sold separately).
