DO NOT POINT THE CAMERA INTO DIRECT SUNLIGHT,
VERY BRIGHT LIGHT SOURCES, OR HIGH-ENERGY LIGHT
SOURCES (e.g. laser beams)! This may cause permanent
damage to the internal filter or the camera.
Note: Internal filtration requires additional shimming and does not work with
ALEXA Studio or ALEXA XT Studio. For PL mount lenses, the IFM-1 filters work
only with a lens mounting depth of 31.50 mm maximum.
Benefits of in-camera filtration
Filtering behind the lens rather than in front reduces weight, reflections
and operational complexity. The filters’ in-camera position significantly
reduces the camera’s total and front weight (because internal filters are
smaller and lighter than external ones).
Also, internal filters are far less exposed to damage than external ones
and, since lenses are changed more frequently than ND filters, the
FSND filters provide extra protection for the sensor.
The Full Spectrum Neutral Density (FSND) filters for IFM-1 are based on
new technologies that assure highest image quality. An absorptive full
spectrum ND coating attenuates the light while maintaining a perfectly
neutral color balance at all densities.
A base of water-white optical glass, precision-polished to create
perfectly parallel surfaces, guarantees a clear and sharp image.
Additional broadband anti-reflective multi-coating reduces internal
reflections and ensures a high image contrast. FSND filters for IFM-1
are available in eight densities from ND 0.3 to ND 2.4 and can be
purchased separately or in sets.
