Sigma warns of aberration bug affecting some of its lenses on Canon DSLRs

DPReview News

Sigma has issued an advisory for five of its lenses over an error that occurs when they're used with select Canon DSLRs.

The issue crops up when the cameras' "Lens aberration correction" function is turned on. According to the company, having the lens aberration feature enabled on the Canon EOS 6D Mark II, EOS 9000D (77D), EOS Kiss X9 (EOS Rebel SL2), or the EOS Kiss X9i (EOS Rebel T7i) cameras will result in an error when paired with the following lenses:

  • 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

Affected users are advised to keep the lens aberration function disabled until a fix is released.

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.
