Phase have in the past years made some updates to their AF, but so have Canon, Nikon, and yes, Hasselblad who have all moved substantially ahead themselves.
I've also used the AFD II, and it was a pretty terrible camera.
In normal light, normal distance, normal objects - you would still have a lot of hunting, slowness and errors.
That is what I call bad AF.
That does not happen anymore.
AF is now fast - not lightning fast - accurate, and no hunting.
That is all I need for my type of work.
In the past I did work that required optimal AF - so I used various 1D models.
Those have an absolutely spectacular AF with 45 points.
I don't know how they upgraded them since, but it doesn't really matter.
What Canon had 10 years ago is much better than any of the MFDs today.
I am now looking for a system with the consideration of 80% image quality and not even 20% AF.
DF+ gives me that, as the new AF gives me no trouble.
If I was looking for a system based on 80% AF and 20% IQ, or even 50-50, then 35mm wins.
I would be very surprised if any MF shop comes with an AF system that can rival any generation 1D.
That is not what most of their clients are looking for.
My understanding based on some conversation with H users, is that even the newest H bodies are much closer to Mamiya than to Canon.
No one is contesting that H AF is better than Mamiya.
We are just saying it's not so bad anymore, and good enough for tripod mounted kind of work.
