Fujifilm X-T4 Dynamic Range Data (vs X-T3, X-Pro3)

Share

Photons to Photos has published its Fujifilm X-T4 dynamic range measurement data.

The Fujifilm X-T4 basically performs identical to the X-T3. The Fujifilm X-Pro3 seems to be superior, but as Blill Claff from PTP explained to us:

The X-Pro3 appears to have improved PDR but it is an illusion.

It’s well known that Fuji implements the ISO setting in an unusual way.
In this case they have given ISO 320 to ISO 12800 an addition 1 stop boost.

Fuji uses a proprietary Exif tag called “Raw Exposure Bias” to indicate how much they have shifted the raw data from “standard”.

Adjusted in Excel for Raw Exposure Bias we see that the X-Pro3 and X-T3 are essentially identical. (They shift to dual conversion gain at a slightly different point).

Sigma and Samyang Fujifilm X Mount Autofocus Lenses Reviews

Share

Since Fujifilm opened its lens protocols to third party manufacturers, lots have happened rather quickly in terms of autofocus lenses for the X system.

So today I decided to dedicate a roundup to the latest X mount autofocus additions to the system, the Samyang 12mm f/2.0 AF and the Sigma X mount trinity.

Overall I can say that none can match the very latest releases coming from Fujifilm (with the XF56mmF1.2 getting an overall performance boost in 2022, too).

But it is also true that price matters and the new third party AF lenses definitely offer a fine performance for the price.

BREAKING: Fujifilm X-H2 coming with New 26 Megapixel Sensor

Share

When we told you about the Fujifilm X-H2 coming with a 26 megapixel sensor, most of us speculated that it would be the current 26 MP X-Trans IV sensor, but used in combination with a new processor it would perform better.

And I get it, I also thought this could be an option, especially considering that Fujifilm did the exact same thing with the Fujifilm GFX50SII: use the old sensor but a new processor to improve performance.

But if you read again the article I wrote last year in regards to this rumor, I literally also wrote:

It would be very atypical for Fujifilm to launch in one year (2022) two completely new higher-end APS-C sensors. But just because Fujifilm never did it before, it does not mean it can’t happen with the Fujifilm X-H2.

And according to our sources this is exactly what is going to happen.

In fact, I have been told the the 26MP sensor on the Fujifilm X-H2 will be a “new sensor”.

And remember, there will be also a 40MP Fujifilm X-H2, and that one is (obviously) new, too.

I have no doubts my sources are 100% accurate, and you should not doubt them either ;).

Just stay tuned on FujiRumors to know more details soon.

It’s going to get very wild with rumors now ;).

Is Fujifilm Nordic Teasing a Fujifilm GFX with Stacked Sensor?

Share

Fujifilm Nordic has released a new Webinar.

Contrary to what we were used so far, this time they also included non Fujifilm X Photographers to the talk, meaning photographers that are not part of the official X photographers program, but who simply started using X or GFX gear, even though they have no relationship with Fujifilm Corporation.

The first not official X/GFX photographer to be part of the Fujifilm Nordic Webinar series is called Soren Solkaer.

  • Soren Solkaer went digital since 2002
  • he instantly started shooting with Full Frame digital (but in his analog times he shot medium format)
  • about 1 year ago, his prost production guy told him “Sir, we have to talk, there is a new camera in town“
  • Soren was very skeptical. He didn’t want to change his camera as he was so used to his full frame gear
  • his post production partner told him there are files now, that are way better than his full frame files
  • in some of his exhibitions he prints 2×3 meters big, and squeezing that our of full frame can be done, but having a bigger file is a huge advantage
  • his post production partner told him the files of GFX are bigger and the quality is just amazing
  • despite being very reluctant, he tried out the GFX system and he saw that his post production partner was right
  • he did not start with the 50MP GFX but he started right with the 100MP GFX100S
  • on top of the resolution, there were many other things that hugely impress him of the Fujifilm GFX100S
  • he needed to get used to the menu, the buttons, etc
  • in the last 25 years he mainly took portraits of celebrities
  • the interviewer asks about the speed of the GFX100S, and he says that he shoots full manual control (except for autofocus), and after a bit of time of getting used, he now gets 100 out of 100 perfectly exposed and focused images
  • in some other of his project the file size itself is not necessary at all, and in those cases he still uses his full frame gear
  • lately for a projects he photographs bird formations flying in the sky at fairly low light. He shoots at 1/500 of a second and wide aperture, so he only has the ISO left to adjust. And the higher he goes with ISO, what is gained in resolution with the GFX100S, is lost in noise at high ISO.
  • another issue: GFX100S shoots at 5fps continuous AF. For birds, the more fps you get the higher the chance to nail the right moment

And here comes Soren’s question: Will there be any improvements down the line in terms of sensitivity and also buffer? Here is what Fujifilm Nordic answers:

  • there are some secrets Fujifilm Nordic can not reveal, but what they can say is that in May there will be an X summit with an announcement, where we will see new sensor and also new processor technology
  • there will be definitely a speed improvement on the APS-C X system, so why shouldn’t those improvements drop down also to the GFX system?
  • Actually the whole GFX system started this way: first 5 years with X system, then Fuji started with the GFX system and pulled the technical stuff of the GFX system into the X system
  • without telling every secret, but GFX system will get faster and faster with the new hardware
  • speed will increase on the GFX system
  • Fujifilm Nordic can’t tell when, but they are confident that it will go into that direction [of more speed]
  • one day Soren will get a medium format camera that can burst quite a lot more than the current GFX cameras
  • “we are working on it, definitely“

I guess it is safe to assume that Fujifilm Nordic is referring to the stacked APS-C sensor to be announced in May 2022 (as Fujifilm officially teased here) and hence hint to the possibility that the stacked technology could find its way also into future GFX cameras.

Just to be clear, so far in terms of rumors I have no hints about any stacked sensor GFX camera coming. Of course this doesn’t mean it won’t come, I just say that at the time of this article I have no information about it.

The summary above is just an extract of Soren’s part of the talk with Fujifilm Nordic. But actually the whole 2 hours talk also with the official Fujifilm X Photographers is well worth a listen. So make sure to check it out down below.
