Tuesday, August 21, 2012
Canon EF 40mm f/2.8 STM Lens firmware v1.2.0 is now available for download (for Mac OS only at this time).
Firmware Version 1.2.0 addresses the following phenomenon
1. If pressure is applied to the lens barrel while the lens is mounted to the camera (pressure can be applied even while attaching the lens cap or while carrying the camera with the lens attached in a bag), the autofocusing function of the lens may stop working.
A Canon EOS 1D X, 5D III (at v1.1.3 or later) or a Rebel T4i/650D is needed to install the upgrade. Alternatively, the lens can be sent to Canon Service to have the firmware upgrade installed.
