aperture problem

Canon has issued a firmware update for the 5D Mark II.  Firmware version 2.0.7 addresses the following issues, which were introduced in firmware versions 2.0.4 and 2.0.3.

  1. Fixes a phenomenon in which the aperture exhibits abnormal movement when shooting movies in manual exposure mode and Aperture Priority AE (Av mode) using some Canon lenses (such as macro lenses).
  2. Fixes a phenomenon in which the exposure level shown in the LCD panel differs from what is shown in the viewfinder when shooting still images in manual exposure mode.
  3. Fixes a phenomenon in which the Wireless File Transmitter (WFT-E4 or WFT-E4 II) may not automatically power off when used for FTP transfers.

Download and installation instructions for the firmware are available on Canon’s website.
