As with most new Canon DSLR releases, there are some third party lenses that may present the odd vignette when “Lens Aberration Correction” is turned on with various Canon DSLRs.
From Sigma:
We have found that some SIGMA interchangeable lenses for CANON are not fully compatible with CANON EOS 6D Mark II released on August 4th, as well as EOS 9000D (77D), EOS Kiss X9i (Rebel T7i) and EOS Kiss X9 (Rebel SL2).
When certain lenses are attached to these cameras and the “Lens aberration correction” function on these cameras is set to “Enable” for Live View shooting, an error would occur.
Please set the “Lens aberration correction” function of the cameras to “Disable” when using SIGMA’s interchangeable lenses for CANON.
In addition, please also refer to other notice below, related to the usage of EOS mount SIGMA lenses on Canon cameras.
Phenomenon
When the lenses listed below are used on EOS 6D Mark II, EOS 9000D, EOS Kiss X9i, or EOS Kiss X9 and the “Lens aberration correction” function on the camera is set to “Enable” for Live View shooting, an error would occur.

Usage Notice for customers who are using EOS mount SIGMA lenses on CANON cameras
When using the SIGMA lenses for CANON, “Peripheral illumination correction”, “Chromatic aberration correction”, “Diffraction correction” as well as “Distortion correction” from the “Lens aberration correction” function of the camera are not supported. Therefore, we recommend you to set them to “Disable”.
If those functions are set to “Enable”, the performance of the lenses may not be accurate.
