17.1.4 Mounting in-camera filters
Internal filters are very delicate. Before you mount or change a filter,
check the lens mounting depth (see Chapters Safety instructions for in-
camera filtration on page 221 and Maximum lens mounting depth on
page 221).
Note: By default, the filter position in the lens mount of the ALEXA XT (except
ALEXA XT Studio) is occupied by the IFM Empty Filter Frame. This glassless
filter ring must be replaced by a real filter or IFM Optical Clear filter, once the
camera is shimmed for IFM-1 use (see Chapter Shimming the lens mount on
page 228)
