Re: What is advantage and disadvantage between X-trans vs Bayer array

"The Fujifilm X-Trans CMOS sensor used in the X-Pro1 is claimed to provide higher resolution than full-frame sensors, and also produce better colour reproduction.

Anti-aliasing filters are used on standard Bayer Array Sensors to reduce moiré effect when shooting regular patterns - however they are known to slightly reduce resolution. The "X-Trans" CMOS sensor uses an irregular pattern of pixels (similar to that found onSilver halide film) in order to reduce moiré without the need for an AA filter.

This same irregular pattern ensures that all horizontal and vertical lines of pixels contain at least one R, G and B pixel whereas Bayer array sensors do not have R and B in some lines resulting in false colour reproduction."

In practical terms - the removal of the AA filter (which is a filter, another thing between the light and a sensor) means you get "more photons" available to hit the sensor.

The X-Trans CMOS just means they removed the standard "pattern" which was subject to the moire effect (shooting screen windows at suspect angles or certain fabric shots) and allows the light photons to hit the sensor through fewer "filters."

Meaning you get more light available in your shots; and then the magic in front of that is amazing glass and behind all that in the sensor and software are just amazing Fuji colors.

Shoot with a standard CMOS sensor and then the X-Trans and you will see the differences.  Subtle but there.
