*note I incorrectly named the EF 70-300 f/4-5.6L IS as the lens pertaining to the issue, when in fact it is the brand new EF 70-300mm f/4-5.6 IS II USM lens. Sorry about that.

Canon appears to have updated every legacy DSLR that has aberration correction to fix an issue with the EF 70-300mm f/4-5.6 IS II USM.

  1. Corrects a phenomenon in which when using the camera with the EF 70-300mm f/4-5.6 IS II USM lens, even if lens aberration correction is set to “Enable”, correction will not be applied.

The following DSLRs have available firmware updates.

Happy firmware updating!
