High quality internal full-spectrum ND filters
Using internal ND filters allows a rating at the base sensitivity of EI 800 without the need for external ND filters, even in bright sunlight. Filtering behind the lens rather than in front saves time and reduces weight, reflections and complexity. In addition it decreases narcissism, which is an unwanted reflection between the last lens element and the sensor and protects the sensor from dirt contamination during lens changes.
The FSND (Full Spectrum Neutral Density) filters used with the IFM-1 are based on a number of high-tech manufacturing methods that are very different from common external filters. A spectacularly neutral colour balance at all densities is achieved through a broadband absorptive coating that attenuates the full spectrum. To maintain a high contrast, an anti-reflective multi-coating reduces internal reflections. A sharp image is assured through a base of water-white optical glass that is precision polished to create perfectly parallel surfaces. While all ALEXA XT cameras come with the IFM filter holder installed, the FSND filters themselves are available separately in 8 densities from ND 0.3 to ND 2.4 plus an optical clear. Out of the box the ALEXA XT cameras can be used without a filter, and when FSND filters should be used, a IFM shim has to be installed in the lens mount.
