FIRMWARE UPDATE 1.0.8

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 also helped other users. This time the update has been released for the EOS 1D Mark IV and EOS Rebel T2i/550D.

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