Firmware update for SIGMA lenses in Canon mount
3

Today Sigma released as promised firmware update for several Canon mount lenses:

This firmware allows compatibility with Canon’s in-camera Lens Aberration Correction function to enable correction matching the optical characteristics of each lens. It also corrects the phenomenon that abnormal images appear or operation errors occur when the function is enabled.

[Applicable products]
SIGMA 35mm F1.4 DG HSM | Art Canon
SIGMA 50mm F1.4 DG HSM | Art Canon
SIGMA 85mm F1.4 DG HSM | Art Canon
SIGMA 135mm F1.8 DG HSM | Art Canon
SIGMA 18-35mm F1.8 DC HSM | Art Canon
SIGMA 24-70mm F2.8 DG OS HSM | Art Canon
SIGMA 100-400mm F5-6.3 DG OS HSM | Contemporary Canon

[Benefits of the update]
・It ensures compatibility with Canon’s in-camera Lens Aberration Correction function, which enables correction matching the optical characteristics of the attached lens. ※
・It corrects the phenomenon that abnormal images appear or operation errors occur when Canon’s in-camera Lens Aberration Correction function is enabled.
・It corrects the phenomenon that exposure during shooting through the viewfinder or Live View mode becomes unstable.
・It improves focus accuracy during Live View mode. (SIGMA 50mm F1.4 DG HSM | Art only)

※ Compatible Canon camera models:EOS 1DX mark Ⅱ, EOS 5Ds, EOS 5DsR, EOS 5D mark Ⅳ, EOS 6D mark Ⅱ, EOS 80D, EOS 8000D(EOS Rebel T6s, EOS 760D), EOS 9000D(EOS 77D), EOS Kiss X8i(EOS Rebel T6i, EOS 750D), EOS Kiss X9i(EOS Rebel T7i, EOS 800D), EOS Kiss X9(EOS Rebel SL2, EOS 200D)

So it benefits mainly Canon shooters who use JPEG. I successfully updated my 18-35, made couple photos with 80D where I can see some differences but will have to test it more properly later.

By the way, there are updates in the works for most, if not all, of the Global series:
