Fujifilm GFX100S II Coming First Months of 2024: Speculating about Differences to GFX100 II

Fujifilm GFX100SII
Speculated Specs and Questions

We recently told you that the Fujifilm GFX100S II will come in the first months 2024.

So the question now is: what could be the differences or similarities between the Fujifilm GFX100S II and the Fujifilm GFX100 II?

To be clear: these are just speculations, not rumors.

  • lower price than GFX100II
  • lower EVF resolution
  • still no battery grip option
  • lower bursts rates than GFX100II
  • smaller body
  • a bit inferior video specs (due to smaller body and not optimal heat dissipation)
  • no full size HDMI and Ethernet port

I think the list above makes a whole lot of sense. But now it gets tougher and the question are:

  • will the GFX100 II have the new optimized 100MP sensor (improved readout circuits, microlenses etc) or will it use the older non-optimized 100MP sensor to keep price as low as possible?
  • will it have only SD-card slots or also a CFexpress card slot?
  • will it offer Frame.io integration in camera body or not?

And last but not least (and maybe most importantly):

  • will the GFX100S II still have the PSAM layout or will retro dials return on GFX with the GFX100S II?

These are just some of my personal non-rumor based speculations and questions. Feel free to add yours in the comments below.

As usual, all the answers will follow on FujiRumors.com.

Fujifilm GFX100S MEGA-DISCOUNT Extended

Fujifilm has decided to extend its insane deal on the Fujifilm GFX100S until December 31.

FujiRumors told you from one of the most beautiful lakes in the Dolomites, that the Fujifilm GFX100SII is coming.

But in that video I also told you that, as an owner of GFX100S myself, for that price, with that discount, the GFX100S is still an excellent pick, even if the successor is coming.

Internal Fujifilm GFX100II Slide Claims 97% Eye AF Accuracy with GF55mmF1.7 in Studio Use

One of the questions is how accurate the Fujifilm GFX100II eye autofocus is.

A kind source decided to answer this question, and passed me an internal Fujifilm slide about the Fujifilm GFX100II, which shows that, for portraits and coupled with the Fujinon GF55mm f/1.7, Fujifilm has calculated a 97% autofocus accuracy.

This is of course for portraits. We are not talking about the accuracy when tracking any athlete running at full speed or something like that.

But I guess the most realistic scenario for the combination GFX100II and GF55mmF1.7 is anyway portraits or not really fast moving subjects (people at a wedding etc).

Fujifilm GFX100 II: The Truth about ISO 80 and the 30% Increased Dynamic Range

ISO 80 and Dynamic Range

We have just covered the talk about the the new sensor of the Fujifilm GFX100II and the up to twice readout speed.

At the end of that article, when I listed the reasons why to get the GFX100II instead of the GFX100S, I wrote the GFX100II has 30% (or 1/3rd of a stop) better dynamic range.

And since I noticed this is another thing that some people struggled with, I decided to elaborate now more in depth.

After testing the dynamic range, Jim Kasson (linked below) agreed that yes, dynamic range is increased, but not by 30%. Jim says:

At ISO 80 those folks at Fujifilm have dropped all the data below the nominal black point, slicing off the left half of the histogram, and cutting the measured read noise in half of what it would normally be. […] You’ll still get slightly improved FWC — but I don’t measure the claimed 30% improvement — and decently low read noise. So it’s an improvement, but not a huge one.

Now, whatever Fujifilm does in terms of software, that has been measured by Jim and I won’t argue that. And it is true that this does make ISO80 dynamic range look crazy good.

But what Fujifilm at the end of the day said, is that there is a 30% dynamic range increase.

What does this mean?

Well, 30% expressed in stops means about 1/3rd of a stop improvement. As a reference, 1 stop increase means doubling the amount of light you let in on the sensor.

So the misunderstand is simple: if the GFX100S has let’s say 14 stops DR, it does not mean that Fujifilm claimed the GFX100II has 18 stops dynamic range (+30%), but 14,3 stops of DR (+1/3). And moreoever, in the X summit the 30% increase is mentioned in the video section of the summit, and Fujifilm has not been clear if it applies also to stills.

What I can say, is that 1/3 DR increase for stills what a Fujifilm rep told me personally during a Fujifilm event. He told me Fujifilm Italy made its own measurements once they got the camera from Japan, and at base ISO they noticed a 1/3 to 2/3 of a stop DR increase.

Now, why did Fujifilm say 30% instead of 1/3rd of a stop, even though they mean the same?

Well, I guess it just sounds better saying 30% rather than 1/3rd of a stop, but of course it can create confusion.

So yes, at base ISO the new Fujifilm GFX100II will give you the better dynamic range over the GFX100S. Also Jim confirms this. But not by a very large margin. Fujifilm says it is 1/3rd of a stop for video, and Fujifilm Italy told me they measured that too for stills.

Fujifilm GFX100 II Engineers and The Truth About the “New” Sensor and “Up to Twice” Readout Speed

Fujifilm GFX100II

Over the past few weeks, many have contacted me asking why I don’t talk about the reports that claim:

  • the Fujifilm GFX100 II sensor is not new
  • the Fujifilm GFX100 II does not read out at twice the speed and faster readout speed is achieved only with software tricks, meaning dropping down at 12 bit when in 8 fps mode

The answer is simple:

When Fujifilm published their first Fujifilm GFX100II development story episodes, they said they would talk about the GFX100II sensor in future episodes.

This is why I decided to wait, hear Fujifilm’s position, and then write an article that is as comprehensive and complete as possible.

And I am happy I waited, because in the 5th X Lab episode dedicated to the GFX100II, we get some helpful insights in the inner workings of the sensor (full episode with summary below)..

But before we dive into it, let me express my admiration for Jim Kasson’s brilliant work in analyzing the inner workings of the GFX100II and to Petapixel for bringing his findings to the attention of the larger public.

I decided to wait for more details coming from Fujifilm before reporting about it, but maybe they would not have disclosed those in such detail, if Jim would not have done his great work, and Petapixel made a huge buzz out of it.
