James:

I finally got my 9000 last week and have been experimenting with it since. 
The as-supplied medium format film holder is a joke indeed! How indeed could 
it be assumed that the film would be anywhere near flat and ttightly 
fitting? The non-rotating glass MF film holder looks to be idiot proof or so 
I've so far.

You mentioned below to select an autofocus point for each frame on an area 
of pure colour.

How does one auto focus on a particular point of a frame?

John
