Chapter 1.Revolutionary CMOS Sensor

The power of the revolutionary "X-Trans CMOS" sensor
which delivers premium image quality that “outperforms
that of full-size SLRs”

The APS size for securing the overall size and high image quality,
as proved by FUJIFILM X100

・As the flagship model of the X series, the X-Pro1 has the mission of delivering high picture quality that meets the demands of professional photographers and offering the size that provides advanced maneuverability at the same time. To fulfill both of these major objectives, APS was the optimum format, as proven by X100. ・X-Pro1 has gone one step further to achieve the level of picture quality that outperforms that of other interchangeable lens cameras and even full-size SLRs. ・The appeal of interchangeable lens cameras is their ability to offer different types of photography according to the characteristics of lens to be used.
Fujinon XF lenses are designed to take in as much light as possible to deliver premium image quality. With the X-Pro1, Fujifilm worked on developing a sensor that can receive the maximum amount of light that comes through the specially-designed lenses.

Moiré* and optical low-pass filters

Moiré* and optical low-pass filters

In order to achieve premium image quality, Fujifilm focused on the factors that affect lens and sensor performance Most digital cameras that have a Four Thirds or larger sensor use optical low-pass filters to reduce moiré patterns. Having a larger sensor broadens the dot pitch to provide a sharp optical image, but increases the rate of the moiré pattern occurring at the same time. In order to reduce this rate, optical low-pass filters are placed between the lens and the sensor however this also reduces resolution

Moiré: When multiple layers of periodic patterns are overlaid, the displacement of the periodicity creates an illusory pattern called moiré.


・Even if you use a high-resolution lens, optical low-pass filters, which sacrifice the resolution, have to be applied to control moiré patterns… This is an inevitable fate of today's digital cameras.
In other words, eliminating the use of optical low-pass filters could deliver images of higher resolution.
