Canon updates the 15-45, 18-150 and 55-200mm for the M50’s Dual Sensing IS
By| March 6, 2018
Canon has released updates for the three EF-M lenses to support dual sensing IS – which is a combination of both in camera body and lens based shake detection which is used by the lens to determine the amount of stabilization required.
Right now, only the EOS-M50 supports dual sensing IS.
The firmware can be found on the lens pages at Canon USA under “firmware”;
