Compatibility with Newer Canon EOS Bodies
Please note that when using a Sigma lens on newer Canon EOS bodies, the MO (manual overrid) function is unavailable. When using a Sigma lens on a Canon EOS body, setting lens corrections to DISABLE is recommended as peripheral illuminaition correction, chromatic abberation correction, diffraction correction and distoration correction are not supported when using these lenses. If these functions are not disabled, the performance of the lenses may be inaccurate and/or may cause artifacts in your images.
