Re: X-A1 = X100 non trans with lenses in a small body

You do realize that X-Trans is nothing more than a new type of CFA - a filter that goes in front of a sensor. X-Trans is not a new sensor tech.


Traditional sensors are B&W sensors, they cannot detect colour - the CFA has to filter out specific colours for each pixel. Only Foveon sensors can detect all 3 colours in each pixel.

The traditional CFA is a Bayer array which usually has another filter (AA filter) in front it to control moiré.

You can read all about the CFAs from the paper below.


You can put any type of CFA you want in front of any sensor type.

Fuji came up with the CFA, Sony makes the sensors.

Maybe Fuji doesn't make their own sensors; I'm no technical genius and have only read opinions for other non-technical geniuses.

Don't take my word for it. Trust the Fuji X-Pert (Rico P.) who literally wrote the book on Fuji X cameras.

He said:

"It took a while, but Fujifilm finally decided to officially announce the X-A1, the long-planned sister model of the X-M1. Let’s cut right to the chase: There’s little difference between these cameras. They look very much the same, they offer the same buttons and controls, the same processor, the same operating speed/performance, the same features, the same menus, the same build, material and size, even the same 16 MP Sony sensor. Of course, there’s one minor but important difference to mention in the sensor department: The X-M1 features an X-Trans color filter array (CFA) without an anti-aliasing (AA) filter, while the X-A1 uses a conventional Bayer CFA with an AA filter (to reduce/eliminate unwanted moiré)."

I agree that the Bayer sensor in the entry level Fuji is probably a Sony sensor but that has nothing to do with the X-Trans sensors.

Two completely different technologies.

And I hate to sound completely ignorant but who is Rico P? Does he work for Fuji?

I've only been using an X-E1 since they were introduced so maybe I'm just too new to the Fuji X cameras to know who the technical experts are.
