Depends on the port; do you mean the regular port with the red plastic front? The batteries were dead in my digital calipers, but it looks like it measures 120mm. Yours probably won't work, but I believe that Reefnet has a swing away adapter designed specifically for it. There's also an older 4/3 flat port- I used to run that with a swing away adapter along with the 12-40; it was a good option for fish portraits and near-macro shots (with a diopter)- the 12-40 is sharp enough to give you some head room to crop. For what it's worth, I've since gone to a dome and the dedicated macro port (which has 67mm threads) for all around better performance- I just have to choose one or the other.
