Drop-In Filter - Canon EF 800mm f/5.6L IS USM Instruction

10. Drop-In Filters
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.
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.
