Ahh, what it is to have friends in high places! Still, waiting is half the fun, no?

We used two 1DX II Bodies for a wedding last weekend and came across this weird problem
We get concentric rings around the photos see attached.
originally i thought it was a setting in my camera.... and i couldnt figure it out... even after i reset the camera...
and then it clicked and i realised i was only getting concentric circles when using the Sigma 35 Art 1.4
I then swapped that lens onto another 1DX II body and i got the identical problem also with that body so it seems to be its an issue with the firmware ..
interesting note
- when i downloaded all the files onto our servers and i did a filter for the 35mm 1.4 Art NONE of the photos showed the rings ON the raw images.
- NOT all photos taken with the sigma 35mm showed the Concentric rings on the Body LCD Screen. Only some exhibited this behaviour
- I took OUR the CF card and stuck it in my 5d3 body during the evening of the wedding coverage and noticed when i played back the image ON the 5d3 IT ALSO showed the concentric rings on the LCD Panel ???
- I stuck a 24mm Sigma 1.4 Art on the camera and didnt have issues or the concentric rings
- i could however consistently get the issue with the 2 1DX2 Bodies
Anyone else experienced this ?

Interestingly the firmware just identifies the lens as "35mm". I didn't think that Canon would even recognize non-canon lenses.

Usually what happens with third party lenses is that they use a random Canon lens code when talking to Canon camera bodies. If PIC is turned on, then the camera then tries to apply the stored PIC correction profile for this random lens to the picture, and it results in weirdness because it is obviously not designed for the camera+lens combination.
East Wind Photography said:Is it a random lens or a random lens in that focal length? Wondering if removing all 35mm options using the lens registration tool would help.

Here is an article from LensRentals talking about this issue with a list of third party lenses and their corresponding Canon lens codes: https://www.lensrentals.com/blog/2012/08/canon-illumination-correction-and-third-party-lenses/
