Developed to take advantage of the exceptional resolution of the XF lens, a revolutionary new sensor inspired by film.
Moiré is tackled at its root cause by the innovative color filter array of the new sensor. By enhancing the aperiodicity (randomness) in the array arrangement, the color filter minimizes the generation of moire and false colors, eliminating the necessity for an optical low-pass filter in the lens and enabling the sensor to capture the full “unfiltered” resolution and descriptive quality of the XF lens.
Lens with optical low-pass filters
Traditonal optical low-pass filters inhibit moiré and false colors but consequently lead to a loss in resolution.
The repeating arrangement of the 2x2 pixel sets tends to generate moire and false colors when shooting stripes and other regular patterns.
X-Pro1 No optical low-pass filter
the new filter changes the rules of digital photography. Without using an optical low-pass filter, moiré and false colors are eliminated, but high resolution is maintained.
The high aperiodicity (randomness) of the arrangement of pixels in 6x6 sets reduces the occurrence of moire. Also the presence of an R, B and B pixel in every vertical and horizontal pixel series minimizes the generation of false colors and delivers higher color reproduction fidelity.
