As promised, Canon has released a new firmware for the 400 DO II lens! I will shortly try it out today.

Release notes
"Firmware Version 1.0.9 incorporates the following fix.

Fixes a phenomenon, in rare cases, the IS mechanism may cause the image to jump.

Firmware Version 1.0.9 is for lenses with Firmware Version 1.0.8 or earlier. If the lens' firmware is already Version 1.0.9, it is not necessary to update the firmware.

The lens' firmware version can be checked from the camera's menu."


Suggestion: You may want to post a separate topic about the firmware update, so other owners will see it and it won't be buried in this thread. I think it would help it it's on it's own. I would post it, but I don't own the lens and you or others who have the lens could better explain the issue and why there's an update.

Just One Man's Opinion...
