Though its use is almost universal with Bayer sensors in digital cameras, it is not absolutely necessary. Kodak once produced two digital cameras, the DCS Pro SLR/n and DCS Pro SLR/c (Digital Photography Review,Kodak DCS Pro SLR/c Review, June 2004, Retrieved March 3, 2007) using Bayer sensors without such a filter. However, significant moiré patternswere produced when photographing very fine detail. Retrieved March 3, 2007.
This observation is consistent with a comparison of the images, displayed in Digital Photography Review, taken by the Sigma SD10 (see here) with those taken approximately contemporaneously of the same scene by the Bayer sensor-equipped Nikon D70 (see here)/page15.asp. Both retrieved March 6, 2007.
