Just done a quick read (will reread later). Nice review!
I am quite busy lately but if I get some time I will have to read through your blog well. You wrote some interesting points in there.
I used to want this camera, so did much research; as the format is suitable for travel (more frames with great quality) but the P&S thing might make it a bit dull at times. For me MF should be for full control (of course varies if you got another big one).
As for the focus/recompose, all RF's should have the same issue.
And hey, didn't you crave a GW690 too? Heh. I just have it as an option for a future upgrade to MF. Price is similar to the GA645 for the mk I-II models, RF, biiig negative and not so heavy (compared to the P67).
I see where is the wage of the summer job going to...😀
