Canon has released another firmware update for their popular EOS 7D Digital SLR. This update, version 1.1.2, corrects a phenomenon where the set aperture moves when shooting movies in manual exposure mode using select Canon lenses (such as macro lenses). The update also corrects the behavior of the AF point-selection of the C.Fn III-7 (Manual AF point selection pattern) custom function when set to  and corrects the AF point display for the viewfinder electronic level when shooting in the vertical position. It also corrects misspellings in the Spanish and Thai menus for applicable products.
The Version 1.2.2 firmware is for cameras with firmware up to Version 1.2.1. If the camera’s firmware is already Version 1.2.2, it is not necessary to update the firmware. Note that cameras with the Version 1.2.2 firmware (and also Versions 1.2.0, 1.2.1) cannot be downgraded to a previous firmware version (such as Version 1.1.0).
