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.

Top 10 Gear to Look Forward in 2022 and Your Top Wishes for 2022 (Anything Goes – Almost)

Coming 2022 (For Sure)

So what can we look forward to in 2022?

Well, here are the 10 things we can be sure to enjoy this year (even if some of them are “just” rumors until now).

  1. Fujifilm X-H2
  2. Fujifilm X-H2 – no joke, twice
  3. Fujinon XF150-600
  4. XF 56mm f/1.2 MKII
  5. XF 18-120mm
  6. Viltrox 13mm f/1.4 AF X Mount
  7. GF 20-35mm – possible aperture range shared here
  8. Sigma X mount lenses
  9. More AF X mount lenses from Tamron
  10. TTArtisan 32mmF2.8 X autofocus mount lens

Your Fujifilm Wishes for 2022

Ok, I can hear your questions:

Well, some of those questions I think Fujifilm managers quite categorically already answered in the past, such as the monochrome questions and full frame question. But hey, managers also categorically said that X mount is not compatible with IBIS, and look, at the end we got IBIS, and it is even one of the best in the industry.

I am also working on some other of those questions, and I already have first answers that I won’t share just yet as I want to have it not only twice, but multiple confirmed. I can’t go wrong when I share certain things ;).

But we will talk about all that soon enough.

What I would like from you now, is that you share your top wishes for 2022 in the comments. Anything goes, as long as it has something realistic to it. So for example, wishing for an X-E5 when we just got an X-E4 is not very realistic. Also a big and heavy Fujinon XF600mmF2 probably won’t make much sense, unless you would pay any amount for it and train a lot to be able to carry it around.

Other than that, from cameras to firmware or lenses… whatever your heart desires and wishes, feel free to share it in the comments down below.

Nope, there is No Fujinon XF300mmF4 and XF500mmF5.6 Coming in 2021

Do you know those automatic tennis ball machine launchers that constantly fire off balls at you, so fast that at some point you just can’t catch them all anymore?

Well, it’s not much different with fake rumors ;).

Sometimes the fake rumors are thrown out in the world with a pace, that here on FujiRumors we just can’t debunk them all fast enough.

But I try to catch up, and here is one that passed the FujiRumors firewall so far but will now be set right.

Back in March 2020 we reported about two Fujifilm patents showing a Fujinon XF300mmF4 and Fujinon XF500mmF5.6.

Now, I keep getting emails of people firmly believing that the Fujinon XF300mmF4 and Fujinon XF500mmF5.6 will come out for the summer Olympics 2021 in Tokyo.

And guys, I hate to be the one that brings the bad news, but whoever told you that, it is not going to happen.

As a matter of fact, those lenses won’t even come in 2021.

Will they come in 2022? Or in 2023? Or maybe never? I have no idea at this point.

But I tell you this: I blog on FR since 9 years now, and I have reported about countless of patents. And if I have understood something about patents in all these years, then it’s that there is a long way between a patent and a final product. And often patents never even materialize into a final product.

So, take patents with a grain of salt, always.

With that said, I do hope those lenses will come. Maybe Sigma will do them?

Stay tuned on FujiRumors, and I will give you updates as soon as I have them.
