The lens comes with the drop-in Gelatin Filter Holder 52 holding a glass filter. The holder accepts commercially-available gelatin filters.

Removing and Installing

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.
