Sigma 18-35 Art inaccurate with 80D DPAF?
1

This is strange. I found that my Sigma 18-35/1.8 Art consistently backfocuses when shooting in Live View with my 80D. This occurs in all three DPAF modes. The Canon lenses I tried focus correctly, and the Sigma focuses correctly in the 60D Live View (contrast-detect AF). The lens has the latest 1.02 firmware installed. Has anyone else encountered a similar problem?
