Canon has released a barrage of firmware updates for a number of its mirrorless cameras and a single RF lens, bringing new and improved features, as well as the usual bug fixes. None of the updates offer major improvements in autofocus or other areas, but they all take care of a few ‘phenomena’ and offer support for newer Canon lenses.

We’ll go ahead and get the most minor firmware update out of the way first. The Canon RF 50mm F1.2 L USM lens has received a version 1.0.5 firmware update that ‘Reduces image noise when performing high sensitivity shooting with the RF50mm F1.2 L USM lens attached to the EOS C70 camera.’ How exactly a firmware update for a lens addresses noise issues is a bit intriguing, but it never hurts to have the latest update anyway. You can download firmware version 1.0.5 for the Canon RF 50mm F1.2 L USM lens on Canon’s website.
