Sigma Issues A Lens Incompatibility Warning For Canon 5D Mark IV & Other EOS Cameras

By Kishore Sawh on September 23rd 2016

Earlier this year, as Pye took delivery of an early Canon 1DX MK II with original firmware, we noticed just before he was heading to shoot a weekend long wedding that there was an extremely strange effect occurring on the image when the 1DX was paired with some Sigma ART glass. It look like this:


Now, that was troubling for many reasons, and chief among which was that we all love the Sigma ART glass, so that there was this strange happening which rendered the lenses unusable on that camera was a major disappointment, and Pye had to adjust his gear usage accordingly. Thankfully, the problem was addressed and rectified quickly due to our posting, and we have firmware updates to thank for it. But it seems once again Canon and Sigma just aren’t playing nice together.

Sigma has released a Canon 5D Mark IV incompatibility warning, and the problems seems to be much like the one we experienced with the 1DX MK II. Actually, almost if not identical, with the same work around we reported before the official fix.

Sigma’s Statement:

Thank you for purchasing and using our products.
Please find the following notes on the usage of SIGMA interchangeable lenses for EOS, when attached to Canon EOS 5D Mark IV that is released on September 8th.

  • MO (Manual Override) function is unavailable with this camera (Full-time Manual function can be offered).
  • When using a SIGMA interchangeable lens for EOS, setting the corrections to [Disable] is recommended, as “Lens Correction” functions of the camera, such as Peripheral illumination correction, Chromatic aberration correction, Diffraction correction and Distortion correction are not supported.*

* If those functions are activated, the performance of lenses may not be accurate.
* This is not only for EOS 5D Mark IV, but also for other camera bodies with the same function.
We appreciate your continued support for our company and products.

Interestingly, however, this note from Sigma suggests that this problem is not only an issue for the 5D Mark IV, but to a varying degree across the entire EOS range.

Will Canon and or Sigma figure out a way to fix these problems via firmware? Probably, but it would likely help if any of you test and find these problems and let the companies know. You can find the Sigma official note here.

    I’ve had exactly the same issue with my new 5d mk4 and 35mm sigma art, really disappointed. Can it be fixed??

    I certainly have this problem with my 1DX.  Not so much with my 5DMarkIX.  I’m VERY disappointed.  I will NEVER buy another lens other than Canon for this reason. Following to see if new posts.

    I wish i would have seen this prior to purchasing my 35mm art lens…

    Interesting, this didn’t happen on my 5DM3. I just noticed it when I placed my Sigma art 35 on my 5DM4, but it doesn’t appear when I use the Sigma art 50mm.

    I have no problem with the Sigma 50mm F1.4 ART DG HSM on my 5D IV.  Current software on both.

    Does anyone know if this is still a problem? I’m looking to buy a 5D mk4 with some sigma lenses but I’d rather not make the jump if this is still a problem.

    Same weird effect!! Seeing this for the first time! Why Canon? So stupid this looks. Suddenly a eye popping visual is seen as soon as you unbox the camera and see this! Wtf! You should have at least released a firmware. I don’t know this is a disappointment still!

    I just want to confirm that this is still an issue with the 6D mkii. I just unboxed it and popped on the 85 1.4 Sigma. Just disable corrections for the lens and it works no problem.

    I just got my Canon 5DIV (first full frame camera) and I have the Sigma 50-500mm. When using my lens hood on it, I get vignetting, but when hood is removed, I still get some, but not as bad? Is this because its a FF camera or is this part of this issue? Thank you.

    “turn off peripheral illumination ” as said Adam Rubinstein (désactiver la correction du vignettage en français) … But this occurs only on the JPG file. If you shoot in raw + jpg, it won’t appear in lightroom , which uses the RAW files instead of JPG when the pictures are shooted in both formats. If you shoot in RAW only, it won’t appear on the DSLR screen at all. Just remember that in RAW format the processor doesn’t try to correct anything, that’s why it’s called RAW … compared to JPG, which is pre-rendered and corrected by the Digic + processor of your Canon DSLR

    i have the same experience with my Sigma Art 85mm 1.4 using canon 5d mark IV at F stop below 2.0.. the rings disappear and the lens seem to work ok from f/2.0 up…

    I had this problem on a Tamron 35mm 1.8 I rented last week, but neither of my Sigma ARTs (50 f/1.4 and 24-35 f/2) are showing it. As has been said many times, the solution is so simple I don’t see why it’s a big deal: Just turn off peripheral illumination correction, and get back to shooting.

    Lenses and cameras were so much simpler before digital image capture and autofocus. All it takes is for the camera manufacturer to change their firmware and third-party lens manufacturers have to adapt. During the film days, communication between camera and lens was mechanical. Now, there is information going back and forth between those electrical contact points.

    Canon is not playing with Sigma at all. L-lenses are tested with Canon cameras before a release, and is the recommended solution.

    Very Strange , I used my Sigma 35 mm 1.4 Art lens with my Canon 5D Mark IV yesterday flawlessly and today when I was taking pics. noticed huge rings / circles all over the pictures. Thanks to this website to help to resolve the problem.

    “Incompatibility” and “issue” are big words … I have tried the Sigma Art 35 mm + 50 mm with the Mk IV and they worked perfectly fine. Only the old 1,4/85 mm caused kind of a heavy vignetting. Turned out lens corrections (using them in LR anyway) even before knowing the official “warning”, works great. Résumé: No relevant problems with Sigma lenses on the Mk IV.

      I used the Mark IV tonight with a sigma 35 1.4 art lens, this was the result in camera…

      This is the same image uploaded in lightroom… No editing…

      Thanks for sharing Patricia. I use the Sigma 35mm Art, and had the same results.
      The rings seem to show when using Live View only; whether on the back of the camera or through remote shooting.
      In DPP also, not that I use it for my workflow, the image loads without the rings.
      This indicates that the problem is limited to the way the camera process the digital signal from the lens during the Live View only; and the rings does not affect the actual image taken.
