Sony has just published the flyer with additional details of the IMX461 sensor, the one used by the Fujifilm GFX 100.
“16-bit digital output makes it possible to readout the signals of 102 M effective pixels at high-speed of 2.7 frame/s in still picture mode. In addition, vertical subsampling binning and horizontal pixel binning realize high-speed 12-bit digital output for shooting moving picture.”
Features
Type 3.4 CMOS active pixel type dots
Input clock frequency 72 MHz
All-pixel readout mode – Various readout modes (*)
Rolling shutter function moving picture mode
H driver, V driver and serial communication circuit on chip
+36 dB gain settable by Bayer color in CDS/PGA on chip
We recently reported here, that Sony officially listed the IMX571 26MP Fujifilm X-T3 and the IMX461 100 MP Fujifilm GFX100 sensors on their page.
Now these sensors are also listed at framos.com, and it gives us a few more details:
FUJIFILM X-T3
If you check out the X-T3 sensor details (table below), you will see that Sony’s 26 megapixel sensor has a bit depth that can go up to 16. The Fujifilm X-T3, though, shoots at 14 bit in regular mode and I hear 12 bit in sports mode.
It looks like Fujifilm did not/not yet enable 16bit readout mode, and went for 14 bit instead, because they prioritize speed over image quality.
In fact, 14 bit files are significantly faster to read out than 16 bit files, which, on the other hand, offer lower noise than 14bit.
Now, this is not a rumor, not at this stage… but…
… but I wonder if Fujifilm could enabled 16 bit a later stage via a firmware update, and maybe even give us the option to select between 14 bit for ultimate speed or 16 bit for ultimate image quality.
Anyway, Framos writes:
“The IMX571BQR-C is a diagonal 28.3 mm (Type 1.8) CMOS active pixel type image sensor with a square pixel array and 26.11 M effective pixels. This sensor incorporates maximum 36 dB PGA circuit and 16-bit A/D converter. 16-bit digital output makes it possible to readout the signals of 26.11 M effective pixels at high-speed of 6.84 frame/s in still picture mode. In addition, it realizes 12-bit digital output for high-speed 4K moving picture by window readout mode. This sensor is designed for use in consumer cameras. Please consult your imaging experts at FRAMOS if you have any questions.”
Fuji Guy Billy already said here, that the 25% better heat dissipation of the Fujifilm X-H1 body over the X-T2 body, allows them to run the X-Processor Pro faster in the X-H1 than on the X-T2.
I guess the same will be valid for the Fujifilm X-H2, and hence it will be able to squeeze even more power out of the brand new Fujifilm X Processor 4.
I wonder if that would make it easier for Fujifilm to offer 16 bit on the X-H2.
Fujifilm GFX100
Framos.com also shares the details of the Fujifilm GFX 100 sensor, the IMX461. They write:
“The IMX461AQR-C is a diagonal 55 mm (Type 3.4) CMOS active pixel type image sensor with a square pixel array and 102 M effective pixels. This IC incorporates maximum 36 dB PGA circuit and 16-bit A/D converter. 16-bit digital output makes it possible to readout the signals of 102 M effective pixels at high-speed of 2.7 frame/s in still picture mode. In addition, vertical subsampling binning and 3-horizontal pixel weighted binning realize high-speed 12-bit digital output for shooting moving pictures.

Back in August, Tony and Chelsea Northrup have posted their thoughts about the so-called mirrorless war, where they basically predicted success for full frame, and said Fujifilm will remain a niche product, because it’s only APS-C and they don’t have super fast glass to match full frame DOF. You can see the summary of the video here.
William Chua took the Fujifilm GFX 50R out for some street photography in Cologne. You can read the full blog post and see the samples at williamchua.com. Some excerpts:
Being a GFX 50s user, he was not too excited about this camera. But after using it for a few days, he has to say he loves it more and more
Its a great camera for street photography
might not be as comfortable to use with big glass like the GF 250mm
in a lot of his sample images, he used face detection, and he’s glad to say it works extremely well
Jonas Rask shares his impressions of the Photokina 2018 in the best way possible: by sharing wonderful images taken with Fujifilm GFX 50R and X100F. Check out his article “When the floor dust settles” at jonasrask here.
Kai Wong was at photokina and shares his walkthrough the various booths. Of course he also checked out the Fujifilm GFX 50R. Jump to minute 5:43 here, to check out the part about Fujifilm.
MediumFormat: First Impressions of the Fujifilm GFX 50R at mediumformat
PhoBlographer writes in his Fujifilm GFX 50R first impressions that the Fujifilm GFX 50R is the camera he’s been waiting for. They would like a 50MP X-Trans version and pay even more for it, and faster glass (such as the rumored GF 80mm F1.4) would also be appreciated. Read it all at phoblographer here.
Spanish: The Spanish site albedomedia (translation) goes hands on with the Fujifilm GFX 50R. They share their impressions as well as some media slides including an overview of Fujifilm’s camera history, which you can see below.
Fujifilm GFX 100 MP X-Trans
ThePhoblographer had a talk with Fujifilm USA manager Justin Stailey, mainly about the Fujifilm GFX 50R, but there was also a question about the Fujfiilm GFX 100.
Phoblographer: Why isn’t the GFX 100MP sensor an X Trans sensor? Justin: I don’t think we said that it was or was not X-Trans. but…In Medium Format, the Bayer Sensor has proven to provide excellent image quality
So, despite hinting that a Bayer sensor is more likely than an X-Trans sensor, Fuji Manager Justin did not exclude the possibility it could be a 100 Megapixel X-Trans sensor. Read the whole interview at phoblographer.
