New Fujifilm Patents: Fujinon GF 20-30mmF4, GF 24-50mmF3.5-5.6 and 50-380mmF3.3, 35-280mmF3.3 (Cine Lenses?)

I was debating with myself if I should stop to report about patents at all.

Why?

Because in 10 years of blogging I have shared hundreds of patents on FR, and none has ever seen the light of the day. What I have seen once or twice, is a patent surface only after the real lens had been already announced (making the patent “leak” useless)

The problem?

I notice that when I report about patents, people think this means the patented item will surely come, it’s just a matter of time.

And that’s a problem, because:

So I don’t want to create false hopes by sharing patents, as those are concepts written on paper, and they remain such in 99% of the cases.

On the other hand, this is a rumor site. Those patents exist, even if the products in those patents will never see the light of the day.

So I decided that I will report about patents, but I will put my disclaimers hoping people will read more than just the mere headline.

And today we talk about a couple of GF and probably Cine lens patents surfaced on the web and brought to us thanks to the Japanese website Asobinet here and here.

So let’s look at them one by one below.

Tamron 12-50mm f/4 VC APS-C Mirrorless Lens Patent Spotted

Tamron has filed a patent for a Tamron 12-50mm f/4 APS-C mirrorless lens.

  • Applicant: Tamron Co., Ltd.
  • Publication number: P2022096075
  • Application number: P 2020208971
  • Released: 2022-06-29
  • Name of invention: Zoom lens and imaging device

Digicame-info writes:

This lens is a high magnification zoom that covers wide-angle zoom and standard zoom in one lens, and the concept seems to be close to OMDS’ 8-25mm f/4 and Panasonic’s 20-60mm f/3.5-5.6.

In 99% of the cases patents will remain printed on paper and never see the light of the day as real products.

There are other lenses Tamron has ready for us in future ;).

We already got the two Tamron X mount lenses listed here.

But there will be also an X mount Tamron 11- 20mm F / 2.8 as well as a more mysterious “telephoto zoom”.

Fujinon XF 60mm f/2.5 Macro OIS Patent Spotted

A patent has been registered by Fujifilm that shows a Fujinon XF 60mm f/2.5 Macro OIS. Digicame-info, who spotted the patent and reports here, writes:

There are several examples with different lens configurations, but all of them are macros of 60mm f/2.5 and include an anti-vibration lens group (OIS). The focusing lens (GF1, GF2) moves internally, so it’s inner focus. Will one of these examples be the successor to the current XF60mm f/2.4 R?

You know what I think about patents. In 10 years of blogging I have shared hundreds of those on FR, and maybe only one became real (and I think even that one, we rumored it before the patent even surfaced).

I say it, because people are still desperately waiting for the Fujinon XF 300mm F4 and XF 500mm F5.6, which I warned you already are nowhere near to come (if ever).

Patents are concepts written on paper, and they remain such in 99% of the cases. So please don’t put too much hope in any of them.

Fujifilm has a new Macro in the works, but it’s the XF30mmF2.8 Macro here. And they have also a MKII lens to come this year, but it’s the XF56mmF1.2 MKII here.

  • Applicant: Fujifilm Corporation
    Publication number: P2022083846
    Application number: P 2020195417
    Released:2022-06-06
    Name of invention: Image sensor and imaging device
  • [Issue] We provide an imaging lens with good aberration correction even in proximity shooting conditions, and an imaging device with this imaging lens.

Fujifilm Stacked sensor Patent (for Fujifilm X-H2S)

A patent has surfaced of a stacked sensor Fujifilm camera.

The patent itself says nothing about the Fujifilm X-H2, or megapixel or anything. It basically just explains the function of a stacked sensor in general, which we already know.

Also, they use a rangefinder camera to explain the patent… but that does not mean the next camera will be stacked sensor Fujifilm X-Pro4 ;).

We know that a stacked sensor is coming since 5th generation BSI stacked sensor camera. And we know it will be for the 26 megapixel Fujifilm X-H2S since earlier today (remains to see if also for the Fujifilm X-H2 high resolution).

The patent itself is an endless flow of technical functional details that do not say anything about what the camera is and its specs. But if you are an engineer and maybe love to dive deep into the technical side of things, you can find an except and the link down below.

Stay tuned… so much more is coming ;). Not complicated patents that do not say anything, but solid rumors that will give you a clear idea on what Fujifilm has planed to make Fuji X and GFX shooters happy ;).

Fujifilm Patents Active Sensor Cooling System for Cameras with IBIS (but Really for Fujifilm X-H2 and Fujifilm X-H2S?)

Fujifilm has patented an active sensor cooling system using fan and heat sink for cameras featuring IBIS.

These kind of cooling systems are generally used for video centric cameras like the Panasonic GH6 and S1H, the Canon EOS R5C and the Sony FX3.

I know what you are thinking: this must be for the Fujifilm X-H2, which everybody expects to be the video-centric camera of Fujifilm.

But I have learned one thing in all these years: my speculations are not nearly as accurate as the rumors from our sources. This is why I won’t even try it, and just let it there as a patent, waiting for our sources to give us some more solid indication on the Fujifilm X-H2 cameras.

  • Applicant: Fujifilm Corporation
    Published by:P2022055674
    Application number: P 2020163229
    Released:2022-04-08
    Name of invention: Imaging equipment and imaging method
  • One embodiment of this disclosure technology is to provide an imaging device and imaging method with image stabilization mechanism.
  • In recent years, image sensors may shoot high-quality videos for a long time. It is preferable to use the imaging device in the appropriate temperature range. Shooting high-quality videos consumes a lot of power, and the heat generation from the imaging device itself exceeds the appropriate temperature range. In long-term high-quality video recording, the imaging device works with protection functions such as forcing the shooting to for the protection of the device itself and the safety of the photographer, such as forcing the shooting to exceed the appropriate temperature range. Therefore, it may not be possible to secure enough shooting time for shooting high-quality videos.
  • In addition, when shooting repeatedly, it is not possible to secure enough shooting time when there is no time interval when the temperature of the imaging device that rose when used last time drops to the appropriate range. In addition, in the imaging device with image stabilization function, it is difficult to dissipate heat generated from the image sensor because the heating image sensor is constantly floating at the time of shooting.
  • In light of the situation described above, in this form, we propose an imaging device and imaging method that can rapidly cool the image sensor and secure the shooting time in the appropriate temperature range after the shooting is over or using the image stabilization function.
  • The imaging unit 100 has three heat pipes 180A to 180C. Heat pipes 180A to 180C are heat transport bodies that transport heat. The end of the heat pipe 180A to 180C is installed in sheet metal 108C of the refrigerator 108. In addition, the other end of the heat pipe 180A to 180C is installed in the heat sink 110. As a result, the heat emitted by the cooling system 108 can be transported from 180A to 180C and cooled by the forced cooling mechanism 46 of the destination.
  • Using heat pipes 180A to 180C, the heat generated from the cooling system 108 can be transported and cooled with the forced cooling mechanism 46 of the destination. As a result, there is no need to prepare a forced cooling system with sheet metal 108C of the cooling system 108, and it is possible to make effective use of the space inside the imaging device 2 of the image sensor 20.

Fujinon XF400mm f/4 and Fujinon XF550mm f/5.6 Patents Surfaced

There is a lack of long and fast primes in the Fujinon world. A lack on the market, but not on paper, as Fujifilm has patented a few of them:

Now we have new additions in terms of patents, as Fujifilm patented:

  • Fujinon XF400mm f/4
  • Fujinon XF550mm f/5.6

Particularly the Fujinon XF400mm f/4 seems interesting to FujiRumors readers, as it won our huge telephoto primes survey.

99% of patents remain forever on paper. But it’s good to know Fujifilm keeps looking at long prime options.

Down below you can find the details on both lenses.

Sigma 18-50mm f/2 DC DN Mirrorless APS-C Lens Patent Found

A new patent for the Sigma 18-50mm f/2 DC DN APS-C lens has been found, basically a faster version of the current Sigma 18-50mm f/2.8 DC DN which will come for Fujifilm X mount in December 2022.

Asobinet, who spotted the patent, says [google translated]:

Looking at the lens configuration, it is very similar to the 18-50mm f/2.8 DC DN (not 100% match). Perhaps F2 zoom was one of the options during the examination stage of practical use lenses. However, now that F2.8 zoom has appeared, it seems unlikely that F2 zoom will see the light of day.

I love the size (and price) of the current Sigma 18-50mm f/2.8, but an f/2 version would be a nice addition too.
