As expected and mentioned in our last article, Canon has just announced a firmware update that fixes the “iris jitter” issue that we previously reported here and here for the Canon 5D Mark II on April, 2010, especially affecting macro lenses (but not limited to that kind of lenses).

Fortunately all those efforts to report that issue did help all Canon customers using all HDSLR cameras.

The fix was firstly released for the EOS 5D Mark II and then for EOS 1D Mark IV and EOS Rebel T2i/550D.

Now it’s time for the EOS 7D! This firmware update also fixes other issues as detailed below.

We thank Canon once again for listen to their customers. That really makes a difference.


Extracted from Canon website:

Firmware Version 1.2.2 incorporates the following fixes.

  1. Fixes a phenomenon in which the set aperture moves when shooting movies in manual exposure mode using some Canon lenses (such as macro lenses).
  2. Fixes the AF point-selection behavior of the C.Fn III-7 (Manual AF pt. selec. pattern) custom function when set to [1].
  3. Fixes the AF point display for the viewfinder electronic level when shooting in the vertical position.
  4. Corrects misspellings in the Spanish and Thai menus for applicable products.
