Fujifilm X-Trans sensor

Fujifilm claims that this layout can minimise moiré effects, and in turn increase resolution by eliminating the need for a low-pass filter.

[1] Typical Bayer sensor arrays have RGB photosites in a repeated 2 by 2 pattern.

In contrast, X-Trans sensors have a more irregular pattern of RGB photosites than conventional Bayer array sensors,[2] reducing the likelihood of interference and removing a need for a low-pass filter that lowers image resolution.

[3] Conventional Bayer sensors can also produce false colour as they do not have R and B photosites in some horizontal and vertical lines, Fujifilm claims that X-Trans sensors on the other hand have an improved colour reproduction due to all horizontal and vertical lines containing at least one R, G and B pixel out of every 6.

[5][6] Under certain conditions, cameras equipped with X-Trans II and III sensors can exhibit purple flare/grid artifacts in backlit photos.
