I am sure that is part of it. The Olympus expert on the German Oly forum explains it roughly that the Mark II tries to evaluate the quality of the image in the field and concentrate on that, whatever "quality" means. More often than not, it will be the object closer to the camera. His examples show a nice sharp main object in the foreground and blurred objects in the background. So our problem goes against the way the camera "thinks", and we have to try and find ways to trick it into doing what we want it to.
That all said, I repleat that my mFT 75-300 II is not only blazingly fast focusing, it is also more selective because it uses both CDAF and PDAF, which gives us more freedom of choice. CDAF points can be made really small, and they still work, where PDAF points are crosses that have to cover a larger area in order to work at all. CDAF points are NOT cross type, they are just small areas of the image.
Here is his article on the subject:

Part way down, after the picture of the sprayer, is the crux of the mater. I will follow with a rough English translation after breakfast, though Google translate may do OK.

Would you expect the pana 100-400 to work more like the oly or more like the canon lens in this respect? I am relatively sure that will be my choice but still contemplating oly vs pana camera to pair with it.

As it is a native mFT lens, I would assume that it uses both systems. From what I have heard, it focuses very quickly, so I think it is safe to say it would be more like the little Oly zoom in that respect. I myself am not wild about the IQ on the long end though, which is why I will stay with the Canon/Metabones setup, at least for now, in spite of the slow AF. If I had to choose between the PanaLeica and the Oly 300/4+ MC-14, it would be a no brainer as I seldom need the convenience of the zoom. It would get stuck at 400mm, which is where it is weakest.
What I would love to see Oly make would be a 200-500/3.5-6.3. No need for them to make a 100-400 unless they make it a LOT better, which means bigger lenses, more weight etc. The Canon 100-400 II is superb, but I found it to be too slow focusing with the Metabones. Optically in a class by its self.

Hi Dan, that's a great write up!
I have been holding back on purchasing the mk2
I am still with the mk1. I have also been using the meta/siggy 500f4.5 combo and it is great but heavy. I have arranged a test and wow for the mk2 to try it out with my OLY 300f4, which is super sharp! Like many other birders I have been frustrated by the focusing of the mk1 for BIF. Could you give me some settings for BIF with the Mk2. As your aware the test and wow is only 3 days so dont won't to spend a heap of time experimenting with settings. Is there a great difference between the mk1 and mk2 for BIF. And how would you rate it against the 7dmk2.
Kind regards Mike

Hi Mike,
I haven't had much chance to do BiF with the II yet because of the weather and lack of flying birds. But... I have basically the same setup, that is all AF points active, release priority off, 10fps normal with the I and 15 electronic with the II. The II has much less rolling shutter with the electronic shutter. Much more usable. IS-1, or IS-OFF if you have really good light. The biggest help though has been my action finder. With 400mm it is very hard to keep a bird in the VF, but very easy with the action finder. I point and hope ... er... shoot. It will be easier with the 300mm.
ISO 400 to 800 depending, and anywhere from 0 to + 1 EV against the sky depending on whether it is blue or not. If the lens has a focus limiter, use it! Great feature on the Mark II! Let me know if anything isn't clear or if I can be of further help.
Sold my WE-M1 yesterday. Was actually a bit sorry to see it go. I have really enjoyed that camera!
