64 In-Camera Filter Module IFM-1
7. Place the next filter onto the bottom ring in the camera’s PL mount. The Ground
Glass/Frameglow tool has to be in the 12 o’clock position (1).
8. Align the filter ring’s main notch with the bottom ring’s red nut in the 6 o’clock
position. To ensure an accurate fit, align the filter ring’s other notches with the two
red noses in the bottom ring’s 10:30 and 1:30 positions.
9. After the magnetic filter ring has audibly snapped into position, carefully unscrew
the Ground Glass/Frameglow tool. The filter has to sit precisely on the bottom ring.
10. Mount a lens (observe maximum lens dimensions!), or cover the PL lens mount
properly with its lid (1).
NOTICE
•
All internal filters require a properly shimmed lens mount (see page 55).
To compensate for the change in flange focal depth due to the shim, always
insert the IFM Optical Clear filter when no filtering is needed.
When the camera is no longer shimmed for IFM-1, the glassless IFM Empty
Filter Frame must be placed back into the filter position.
•
Internal filtration does not work with ALEXA SXT Studio. For PL mount lenses,
IFM-1 works only with a lens mounting depth of 31.50 mm maximum.
