Sigma has announced an incompatibility notice for five of its lenses when used with Canon Cameras.

The issue appears when the “lens aberration correction” is turned on the EOS 6D Mark II, EOS 9000D (77D), EOS Kiss X9 (EOS Rebel SL2), or the EOS Kiss X9i (EOS Rebel T7i).
Here is the list of the lenses that might have this issues:

  • SIGMA 30mm F1.4 DC HSM | Art
  • SIGMA 35mm F1.4 DG HSM | Art
  • SIGMA 30mm F1.4 EX DC HSM
  • SIGMA 50mm F1.4 EX DG HSM
  • SIGMA 85mm F1.4 EX DG HSM

It is recommended to keep the “lens aberration correction” feature off until Sigma comes up with the fix.

We have found that some SIGMA interchangeable lenses for CANON are not fully compatible with EOS 6D Mark II, EOS 77D, EOS Rebel T7i, EOS 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.

[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.
