Fujifilm’s First Stacked, Back-Illuminated, X-Trans Sensor Coming in 2022

Fujifilm has announced that it is currently developing a new flagship camera that will feature the company's first back-illuminated, stacked layer X-trans CMOS sensor.

The company has said that to celebrate the tenth anniversary of the X-system, it plans to bring out not only new lenses (which were announced as part of a lens roadmap) but will also launch a new flagship camera that features the company's first combination stacked layer and backside-illuminated X-trans CMOS sensor.

While Fujifilm's current fourth-generation 26.1-megapixel image sensor that is featured in the X-T30, for example, is already backside-illuminated, the company has never used a stacked structure before.

Back-illuminated, also referred interchangeably as backside-illuminated or BSI, sensors are a type of image sensor that uses an arrangement of imaging elements that increase the amount of light captured and therefore improve low light performance. Typical front-side illuminated sensors are constructed similarly to how a human eye works with a lens in front and the photodetectors in the back. While easier and simpler to manufacture, the way the parts that make up the sensor are arranged will actually cause some of the light that hits it to reflect back outwards and reduce the amount of light signal that it is capable of actually recording to make an image.

In contrast, back illumination rearranges the same elements behind the photocathode layer so that the wiring no longer is in front, which improves the light-gathering capabilities from about 60% efficiency to over 90%.

A stacked CMOS is considered a next-generation backside-illuminated sensor and was first developed by Sony in 2012. In this design, the supporting circuitry that was moved behind the photodiodes in a standard backside-illuminated sensor are further moved below the active pixel section and adds an additional 30% improvement to light gathering capability. Because parts have been rearranged on a stacked CMOS sensor, designers can do more with the space. Sony, for example, has built RAM directly into the sensor which has resulted in dramatically improved readout speeds, a system that has allowed the Alpha 7R IV, Alpha 9 II, and Alpha 1 cameras to perform extremely fast frames per second bursts at ever-increasing resolutions.

Generally speaking, this sensor design doesn't improve image quality but instead focuses the benefits at pure speed of data transfer.

In the case of Fujifilm, the company hasn't indicated how much resolution should be expected out of what is likely to be the fifth-generation X-trans sensor, but even if the company chooses to stick around the mid-20-megapixel range, the performance gains from adding that stacked design will very likely be considerable when compared to the fourth-generation sensor currently available.

Fujifilm X-T30 II and X-T3 WW Lightly Update Previous Models

Fujifilm has announced that it will be releasing two new versions of the X-T30 and the X-T3. X-T30 II features a few small updates while the X-T3 WW will not ship with an included charger. Both will be available for cheaper than their predecessors.

The original Fujifilm X-T3 launched in 2018 and features a 26.1-megapixel X-Trans CMOS 4 sensor backed by an X-Processor 4 image processor. That processor allows the camera to work three times faster than the previous X Series cameras and allowed it to shoot at up to 11 frames per second.

The X-T30 launched a year later in 2019 and was the successor to the X-T20. It features a 26.1-megapixel APS-C X-Trans CMOS sensor and the X-Processor 4 Quad-Core CPU. The camera can shoot 30 frames per second at 1.25x crop and 20 frames per second without a crop with the electronic shutter, or 8 frames per second with the mechanical shutter.

Fujifilm says that the updates to the X-T3 WW (WW appears to stand for worldwide) were designed to create new ways to meet Fujifilm customers' needs more efficiently and sustainably. To that end, in order to streamline and consolidate its production for its global consumer base, the company will be launching the X-T3 WW without a battery charger.

There will be no other changes made to the camera. By not including a charger, Fujifilm is able to make a single product that serves the entire global market which reduces its production and administration costs. In addition to those savings, the fact that the charging brick isn't in the box helps reduce the cost of the X-T3 WW from it's current $1,200 to a slightly more affordable $1,100. The body with XF18-55mm lens kit will be priced at $1,500. The X-T3 WW body and kit will be available in a black colorway only.

The X-T30 II is more of a successor to the original than the X-T3 WW is, and features a few updates that improve performance. The camera features improved LCD resolution, -7EV autofocus, and an increase to 240 frames per second video shooting. The X-T30 II will be available in both body only and body with XF18-55mm and XC15-45 lens kit options in black and silver colorways.

The X-T30 II body-only will be available for $100 less than the original model retailed for at $900. The body with the XF18-55mm lens kit will be $1,300 and the body with tje XC15-45mm lens kit will have cost $1,000.

The Fujifilm X-E4 is the Last To Use X-Trans IV Sensor: Report

![image](https://petapixel.com/assets/uploads/2021/01/Fujifilm-Reveals-the-X-E4-The-Smallest-Ever-X-Series-Camera-800x420.jpg" width=)

The Fujifilm X-E4, announced in January, is the last Fujifilm camera to use the company's X-Trans IV sensor, according to a new report. The sensor was first introduced on the X-T3 and later found its way into several other cameras over the course of the last three years.

According to FujiRumors, Fujifilm will no longer use the X-Trans IV sensor that is the heart of the Fujifilm X-T3, X-T30, X-Pro3, X100V, X-T4, X-S10 most recently the X-E4. The X-Trans IV is Fujifilm's fourth-generation backside-illuminated 26.1-megapixel CMOS that the company says integrates the unique X-Trans color filter array to reduce moire and false colors without the need for an optical low pass filter. This combines with its backside-illuminated structure to reduce noise levels and increase image quality.

When the X-Trans IV was first announced as part of the X-T3 release, Fujifilm touted its ability to expand its standard ISO range to ISO 160, which was previously only available via extended ISO. The native ISO range of 160 to 12,800 could then be further expanded to ISO 80 at the new low and ISO 51,200 as the new high.

While the sensor has served as the core of several beloved Fujifilm cameras since its 2018 introduction, this new report alleges that the company is set to leave it behind, meaning the X-E4 will be the last Fujifilm camera to use it.

In the interview above published last month, Fujifilm product manager Takashi Ueno notes that Fujifilm's focus on its XF18mm f/1.4 release was "resolution," which Fuji Rumors reports is a hint that higher-megapixel cameras would come in the future. Building on the report that Fujifilm is set to leave the 26.1-megapixel sensor behind, the hope is that an equally functional but higher resolution sensor will come soon.

Unfortunately, such a sensor and a new camera is unlikely to come this year, Fuji Rumors alleges in a separate report from earlier in the week. According to the rumor, Fujifilm will not release any new X-series cameras for the rest of 2021, which is total turnaround to the company's bustle of activity early in the year as it announced not only the X-E4, but also the GFX100S and multiple lenses including the aforementioned 18mm f/1.4.
