Hi Tord,
I'm glad you like the 400mm. Like I reported before, I also have the focus problem. I can't rely on focus and a few shots are needed to make sure. I find that quite annoying. It gets worse as you increase distance.
I don't seem to experience the problem you have with focus refusing to work. On occasion at close range, it will hunt endlessly but focusing elsewhere fixes the problem.
IBIS works great on mine also, even with the 1.4X or the 2X TC.
I just had a look at the metabones web site and among Canon lenses reported as compatible by community can be found telephoto primes:
Canon EF 200mm f/2.0L IS USM
Canon EF 300mm f/2.8L IS USM (Mark I)
Canon EF 400/2.8L IS USM (Mark I) // comment: this is a heavy lens, so of limited interest.
(The 400mm f/5.6 USM is apparently not listed, for some reason.)

Dan, maybe you are right that about the reflexions.
Jules, I looked on their homepage, it looks like the program is only for free for a trial period of 30 days.
Can you post the same photo with the geese untreated for comparison reasons, please?
Anders
Jules,
#3, hmmm.... interesting. I haven't noticed that and I find it hard to imagine how it could have any effect on focus, but the AS=0 thing can have a big effect. Minute amounts of motion blur or shutter shock can make a shot look out of focus, especially when you don't see any obvious signs of motion blur.
Have to give that a test. Be interesting to find out. I have been using the silent shutter constantly. The fact that it is really silent is a big advantage. These guys are very shy and will take of at the first click.

Bad light, 1/80 wide open. He was only about 4 meters away stayed around much longer than they normally do.
Jules, thanks for the other untreated photo.
Why have they limited upper iso to 3200 while using silent shutter?
Anders
Here is an example of how the silent shutter is effected by rolling shutter. Two shots, hand held, about one second apart. Switch quickly back and forth between the two to see what I mean.

That's right, which is why I will continue to keep using it where silence is an advantage.
