Sigma GF 24mmF2 Lens Patent for Fujifilm GFX

Back in 2023, Sigma’s CEO said that Fujifilm GFX users would be their ideal customers, while also making it clear that Sigma had no plans to produce G-mount lenses at the time.

Then in 2024, the tone changed. Sigma’s CEO stated that if Sigma truly wants to become the “master of optics,” it would eventually need to make lenses for the Fujifilm GFX system.

That statement raised expectations that Sigma GFX lenses could arrive sooner rather than later. However, in 2025, the message shifted once again: Sigma currently has no concrete plans, and GFX lenses are something that might happen “maybe in the distant future.”

So, what’s the situation now?

A newly surfaced Sigma patent may provide a small but interesting clue.

The patent describes an optical design for a 24mm f/2 lens that appears to cover a sensor larger than full frame. Based on the technical specifications, the Japanese website Asobinet speculates that this design could be intended for Fujifilm GFX (44×33mm).

And the fact that Sigma is even investigating and patenting optical designs for GFX-sized sensors is noteworthy.

It suggests a few things:

  • The GFX system’s market share is growing, possibly approaching a point where Sigma sees long-term potential
  • There likely isn’t any “mount protection” preventing third-party manufacturers from producing G-mount lenses, meaning Fujifilm appears open to external lens makers

These are undeniably positive signals.

However, a strong reality check is needed. Over the years, I’ve shared hundreds of patents on FujiRumors. Only once did I spot a patent before it turned into a real, shipping product. In all other cases, patents either surface after a product is announced—or never materialize at all.

We’ve seen this countless times:

So while today’s Sigma patent is encouraging—especially because it shows third-party interest in the G mount—it does not mean Sigma GFX autofocus lenses are just around the corner.

For now, this is best seen as a first signal, not a promise. The road to third-party G-mount AF lenses may still be long—or may never happen at all.

Fujifilm Mysteriously Removes GF32-64mmF4 Firmware From Its Website – UPDATED

UPDATE: Fujifilm put the firmware back online after our article. The issue (probably): Fujifilm seems to have made some re-designs on the website, and maybe they just forgot to upload the GF32-64mm page again.

Fujifilm has so far released two firmware updates for the (currently heavily discounted) Fujinon GF32-64mmF4.

  • ver.1.20 – improved exposure tracking in video and reduced focusing motor noise
  • ver.1.10 –  phase detection support for GFX100

However, for reasons currently unknown, Fujifilm has removed the GF32-64mmF4 firmware from its official website. If you try to access the dedicated firmware page, you’re now greeted with a 404 – Page Not Found error here – cached page here.

At this point, it’s unclear why Fujifilm decided to pull the firmware. Personally, I’m running firmware version 1.20 on my own GF32-64mmF4, and everything works flawlessly. In fact, I really appreciate the faster and quieter autofocus performance it delivers.

That said, firmware doesn’t just disappear from an official support page without a reason. Even if version 1.20 seems perfectly fine in day-to-day use, Fujifilm’s decision to remove it suggests that there may be an underlying issue we’re not aware of yet.

For this reason, I strongly advise fellow GFX shooters not to install firmware version 1.20 if someone happens to share the file privately. Until Fujifilm clarifies the situation or republishes the firmware, it’s better to stay on the safe side.

To Split, or Not to Split: Should Fujifilm Merge the X-H2 and X-H2S Into One X-H3?

Merging the Lines?

I recently asked you whether you’d prefer a DGO or DCG sensor on future Fujifilm cameras.

The results of the survey is here.

But while reading through the comments, something else caught my attention. FR-reader TammyLieJohnes wrote:

But I believe there will be just one Fujifilm X-H3 camera, no ‘S’ and ‘non-S’ model.
It’s going to be stacked 40MP sensor, I hope DCG so we don’t loose so much on e-shutter

That comment raises an interesting and very relevant question: should Fujifilm merge the X-H line into a single flagship model?

RUMOR: Fujifilm is Working on a THIS Camera

The Rumor

So, we have received a rather intriguing rumor.

According to trusted information, Fujifilm is working on a new compact camera with a 1″ sensor.

I personally had lost hope to see a new 1″ compact camera, even though after the release of the – currently substantially rebated – Fujifilm X half I saw an opportunity for one. So I am happy hear from trusted sources that Fujifilm is working on one.

** Please Get it Right **

But here is where I have to be clear… and you should read carefully.

Our sources only told us that Fujifilm is working on a compact camera with 1″ sensor.

They did not tell us if it will be the successor of a known line, or a new camera, or something super-experimental like the Fujifilm X half.

So all we can do for now is to make random speculations.

So let’s do just that, because it’s fun :).

I guess the most obvious speculation is that Fujifilm could revive any of its 2/3rd sensor cameras with a 1″ sensor. So we are talking about a successor to the Fujifilm X30, Fujifilm XQ2 or even the forgotten Netflix star, the Fujifilm XF1.

I mean, Fujifilm already took the leap to 1-inch with the Fujifilm X half, and in a previous article I wondered whether, now that Fujifilm has this sensor “in the house,” they might seize the opportunity to revive some of their beloved discontinued 2/3-inch sensor cameras, but this time with a 1-inch sensor.

In fact, I even ran a survey asking which camera you’d most like to see come back:

In the survey, the Fujifilm X30 successor came out on top.

But again: everything I know so far is about a “compact camera with 1″sensor“.
