How hard can it possibly be to use a non -Bayer pixel pattern like Fuji does? My understanding is Fuji just made the pixel pattern less simple than the little repeating 4-pixel blocks in a Bayer pattern that give us this problem with screen doors/fabric/etc., and this makes the low pass filter unnecessary.
It seems fairly straightforward and not subject to any patent issues vs. Fuji. How could anyone patent "any pattern in the world other than Bayer"?
Note that as a result of using a non-Bayer array, Fuji's cameras have more limited 3rd party support for raw image development than do Bayer array sensors.
That is a good point. I had not thought of it.
HOWEVER, Fuji is Fuji. Canon is Canon. Adobe always does the quickest updates for Canon cameras.
