Sigma 50-140mm F2.8 for Mirrorless APS-C Patent Found

Sigma 50-140mm f/2.8 DC DN

The patent for the Sigma 50-140mm f/2.8 APS-C mirrorless lens has been found.

This would be the first telephoto DC DN (APS-C) lens from Sigma and it would go to compete with one of Fujifilm’s best lenses, the Fujinon XF 50-140mm f/2.8 R LM OIS WR.

  •  Application: Sigma Co., Ltd.
    Public number: P2023090116
    Application number: P 2021204904
    Release date: 2023-06-29
    Name of invention: Imaging optics
  • [Issue] Provides a small imaging optics with a small open F value in the entire zoom range.
  • Mirrorless cameras have a smaller housing due to the abolition of mirrors, so it is required to miniaturize the imaging optics accordingly. In addition, large aperture zoom lenses with small open F values are required throughout the zoom range.
  • In Patent Document 1, a positive read type zoom lens with an open F value of about 2.8, which is bright and the lens group on the object side is fixed to the image surface at the time of variable doubling is disclosed. The convenience and robustness are high due to the fact that the optical total length does not change, but there is a problem that the size of the imaging optical system is large.
  • In Patent Document 2, a positive read zoom lens with a bright open F value of about 2.8 and a shortened optical total length at the wide angle end is disclosed. However, there are many lenses with large diameters that move when multiplying on the image side rather than the opening aperture, so the mechanism required for the transformation is larger and the diameter size of the lens barrel is larger.
  • This invention is made in light of this situation, and aims to provide a small imaging optics with a small open F value throughout the zoom range.
  • Example 1 (for 50-140mm F2.8 APS-C)
    Zoom ratio 2.70
    Wide angle intermediate telephoto
    Focal length 50.50 85.38 136.50
    F number 2.92 2.92 2.92
    Total angle of view 30.62 18.00 11.40
    Statue height 14.20 14.20 14.20
    Lens total length 125.00 137.38 145.00

Viltrox 27mm f/1.2 PRO XF Available in Mid-August

They teased it.

We leaked it.

And now we have a first time indication from Viltrox.

Viltrox has now said on their social media that they expect to launch the Viltrox 27mm f/1.2 in mid-August.

If you want to see hands-on images of this lens as well as a size comparison with the Viltrox 75mm f/1.2, then check out this article.

The Future of GFX: Which Sensor Do You Want for GFX100 Replacement – VOTE NOW

Fujifilm GFX100 Replacement

Until now it always worked like this in the Fujifilm world: Fuji’s APS-C series cameras get the latest and greatest technology and then the same sensors and processors are used on Fuji’s GFX cameras.

With two differences, of course.

  • the GFX sensor is about 4 times larger than the APS-C sensor
  • the GFX sensor has a Bayer filter array instead of X-Trans

But other than that, the silicon wafer used to make these sensors is exactly the same.

This means that for example the 26MP BSI X-Trans IV sensor is the very same we find on the GFX100/S, just Sony cuts a 4 times larger part out of it for the GFX sensor, hence 102 MP.

That’s great for Fujifilm, as it saves them R&D if they can use the same platforms over several systems and, for example, simplify the transfer of their APS-C firmware into their GFX system by using the same processor and sensor technology.

And what this mean for the rumored Fujifilm GFX100 replacement?

Well, if Fujifilm will continue doing what they always do then I see 3 options.

And I say 3 options, because the Fujifilm X-S20 shows us that Fujifilm is still considering that 26MP BSI sensor part of their lineup and hence to be potentially used in future cameras.

The Best Sensor is…

The three most obvious options at this point are:

  • 102 MP non-stacked BSI sensor (same of X-S20)
  • 102 MP stacked BSI sensor (same of X-H2S)
  • 158 MP non-stacked BSI sensor (same of X-T5)

But of course, there are also other sensors that Sony has available. We reported here about:

  • 162 MP stacked BSI sensor (in GFX format)
  • 123 MP global shutter sensor (in GFX format)

Sure, a 162MP stacked medium format sensor would be extremely expensive. And as far as global shutter goes, it’s not usually Fujifilm who uses breakthrough technology for first. Those sensors come from Sony and my guess is that before we don’t get it on a Sony camera, we also won’t see it on a Fuji camera.

That’s why for now I will not include the latter two options in the survey. But if sources tell me crazy things are going to happen with the GFX100 replacement, then you can bet I will let you know first here on FujiRumors.

The Survey

And now to the survey… and the question could not be easier than this one: which sensor do you want on the Fujifilm GFX100 replacement?

Which sensor would you like on the Fujifilm GFX100 Replacement?

Fujifilm FF230002 Registration Found – Expect X-Pro4, X-E5, X-S30, X-T6, X-T40, X-H3, X-H3S, X80, X100VI (X200) and GFX50R Successor Rumors to Magically Appear ;)

Fujifilm has registered the FF230002, so we now have a total of 2 registrations:

  • FF230001
  • FF230002

One of them will certainly be the Fujifilm GFX100 successor, which we already rumored months ago here.

Now, I can see the “rumors” about the Fujifilm GFX50R successor, the Fujifilm X-Pro4, Fujifilm X-E5, Fujifilm X-T6, Fujifilm X-T40, Fujifilm X80, Fujifilm X-H3, Fujifilm X-H3S, Fujifilm X100VI or X200 and more pop up. But those “rumors” appeared also ahead of the X Summit on May 24, and of course none of it materialized. But I guess misleading readers for traffic and good SEO is a great deal for them.

FujiRumors will let you know what the real deal is… clickbait and misleading free as usual ;).

  • FF230002
  • 5.8GHz/5.1GHz/2.4GHz
  • ≤20ppm
  • 5725-5850MHz 5150-5350MHz 2400-2483.5MHz

The patent has been found at cmiitid by the Japanese website asobinet.
