Fujifilm GFX Fixed Lens Camera Lens Patents Spotted – GF35mm F3.5, GF40mm F3.5 and GF50mm F3.5

The following lens patents for the GFX have been spotted by the Japanese website asobinet.

  • GF35mmF3.5
    (more precisely 33mmF3.6)
  • GF40mmF3.5
    (more precisely 39mmF3.6 and 43mmF3.6)
  • GF50mmF3.5
    (more precisely 51mmF3.6)

Asobinet speculates that these are patents for a fixed lens camera, since it has a short back focus.

Fellow FujiRumors readers already know that the fixed lens Fujifilm GFX will come in the first half of 2025 with a 28mm equivalent lens, which means it will be 35mm in GFX format.

All of the patents show an f/3.5 aperture, which would be a f/2.8 depth of field equivalent in full frame.

Tamron Patents Big Zoom Lenses

The following patents for Tamron big zoom lenses have been spotted by asobinet:

  • Tamron 400-1000mm f/10-11.5
  • Tamron 250-700mm f/6.5-13

Asobinet does not specify if these are designed for FF or APS-C (but likely for FF).

The approach is similar to the one of Canon with the Canon RF200-800mm F6.3-9 IS USM: keep costs and size contained thanks to a slower aperture.

As far as long telephoto zooms goes, we Fujifilm shooters are currently covered by the Fujinon XF 150-600mm f/5.6-8 R LM.

Last but not least: if you look at Tamron lenses specifically designed for APS-C, then these are the current patents:

Fujinon XF 8mm F2.8, XF 10mm F2.8 and XF 15mm F2.8 Patents Spotted

  • Fujinon XF 8mm f/2.8
  • Fujinon XF 10mm f/2.8
  • Fujinon XF 15mm f/2.8

Probably just variation of patents shared in the last 10+ years, such as:

The patents have been spotted by the Japanese website asobinet.

And remember, Fujifilm has also patented this foldable smartphone, so that one has to come soon, too :).

More seriously: Fujifilm recently said they have 10 lenses currently under study. Look up at those to see a more realistic list of lenses that might come at some point.

Fujifilm Files Patent Infringement Lawsuit Against Kodak

Fujifilm Files Patent Infringement Lawsuit Against Eastman Kodak Company

Hanover Park, Ill. – FUJIFILM North America Corporation, Graphic Communication Division today announced that FUJIFILM Corporation filed a patent infringement lawsuit against Eastman Kodak Company (NYSE: KODK) in the United States District Court for the District of New Jersey.

Fujifilm has asserted four patents (U.S. Patent Nos. 10,427,443, 10,525,696, 10,875,346, and 11,294,279) pertaining to various aspects of processless lithographic printing plate technologies, including method and apparatus claims.

Fujifilm is seeking remedies including damages and injunctive relief related to Eastman Kodak’s unauthorized commercial manufacture, use, offer to sell, or sale within the United States, and/or importation of its processless lithographic printing plate products that infringe the four asserted patents, including those sold under the product name “SONORA X” and the brand umbrella name “SONORA XTRA”.

“Fujifilm is committed to protecting its significant research and development investments, and in bringing innovative printing plate technologies to customers around the world,” commented Toyoyuki “Tommy” Katagiri, division president, FUJIFILM North America Corporation, Graphic Communication Division. “We will enforce and protect our innovation and intellectual property rights in the United States and around the world when we believe others infringe unfairly.”

Separately in October 2023 and December 2023 respectively, Eastman Kodak’s European subsidiaries, Kodak GmbH, Kodak Graphic Communications GmbH, and Kodak Holding GmbH, were sued by FUJIFILM Corporation for infringement of the related European counterparts of the US patents-in-suit in the Unified Patent Court and in Germany.

“We will continue to protect our intellectual property in processless lithographic printing plates, to the benefit of our customers, including small, family-owned printing businesses, as well as medium- and large-sized printing businesses,” added Katagiri.

Sigma 20mm f/1.4 Patent Spotted (and 23mmF1.4)

The patent for the Sigma 20mm f/1.4 lens (as well as 23mmF1.4) has been spotted by the Japanese website Asobinet here.

This is just a variation of what would ultimately become the Sigma 23mm f/1.4 DC DN, so there are close to zero chances that Sigma will release also the Sigma 20mm f/1.4.

Tamron Will Launch Six Lenses in 2024, and here are the Three Patented Tamron APS-C lenses

Tamron has shared its financial result. In there, they write that they will launch six new lenses in 2024, as highlighted by SonyAlphaRumors.

And in future they might even launch 7 lenses a year.

Of course Tamron covers many mounts, so don’t expect all these lenses to come for Fujifilm.

But there are some dedicated APS-C lenses that Tamron has patented and I will share down below for you.

Feel free to let us know your favourite of the three.

Sigma 50-135mm f/2.8 DC DN APS-C Lens Patent Found

Recently we made a recap of all the Sigma and Tamron patented APS-C lenses.

Well, it looks like we have to add another one to the list as spotted by the Japanese website asobinet:

  • Sigma 50-135mm f/2.8 DC DN

Looking at the patent details, asobinet concludes that aberration is beautifully corrected in the entire zoom area and it has no internal zoom, unlike the Sigma 70-200mm F2.8 DG DN OS full frame lens.

The new patent is very similar to the already patented Sigma 50-140mm f/2.8 DC DN and that was very high on your wishlist when I launched the survey asking you which patented Sigma/Tamron lens you’d like to get.

The Future Sigma and Tamron APS-C lenses in Patents – Vote the Lens You’d Like to Get

In July we wrote a very popular article about Fujifilm’s future based on patents Fuji has filed.

And of course not only Fujifilm is filing all sorts of patents. Also other brands do.

So out of curiosity I’ve looked back into which APS-C lenses Sigma and Tamron have patented.

Which of the ones above would you like to see become real? Vote below.

But always keep in mind: it’s not said that patents will materialize into a real product, as we explained more precisely here.

Fujifilm Patents Fujinon XF 18-300mmF3.5-6.5 OIS, XF 16-200mmF3.5-6.5 OIS and XF 16-150mmF4-6.5 OIS

A few months ago we wrote a dedicated article about “Fujifilm patents”, where we dig deep into every single patent ever registered since the existence of the Fujifilm X series.

And we saw: out of 67 patents, not a single one became a real product until now.

I made this huge effort to go through 10+ years of articles on FujiRumors and find every single patent ever shared, because I noticed the tendency by many in the X shooter community to take such patents as rocksolid indication of what is Fujifilm will launch in future.

My goal is to Invite you to take these patents for what they are: products that in 99,9999% of the cases will exist only on paper.

With that said, today we have three more patents to add to the list as they have been spotted by the Japanese website asobinet.

  • Fujinon XF 18-300mm f/3.5-6.5 OIS

Given the lovely Tamron 18-300mm f/3.5-6.3, I see no urgency for the Fujinon XF 18-300mm f/3.5-6.5 OIS.

  • Fujinon XF 16-150mm f/4-6.5 OIS

The Fujinon XF 16-150mm f/4-6.5 OIS might be a bit too close to the Fujinon XF18-120mm f/4 LM PZ WR and one of my favorite X mount lenses, the XF18-135mmF3.5-5.6 R LM OIS WR

  • Fujinon XF 16-200mm f/3.5-6.5 OIS

Fujinon XF 16-200mm f/3.5-6.5 OIS could be the only that could make sense to me as a meaningful addition to the X series lineup.

But forget patents, follow the rumors.

And the rumors say, that the next XF lens we will get is the replacement of this lens here.
