Interesting read.
His comments on the DF or DF+ bodies, are common. Hopefully with the XF Phase has addressed some of these issues.
The comments on being too expensive, many would agree with that also. It's my personal belief that Phase One missed the market entirely with the IQ150 due to their pricing structure and I think if you look at total sales of the 150 in the US alone they have been very small. The fact that it took Adobe almost a year to add support for the IQ150 points to the small overall demand. It was just added with LR 6.4. But the IQ250 was added almost immediately on it's announcement. But due to the fact that Phase One has always allowed a upgrade program, I guess deems the fact that they can't price the IQ150 in the same market as the Hasselblad 50c. And it's a toss up to say the two backs are direct competitors. But I think that the general impression of the buying public is that the 50MP Phase IQ150 is grossly overpriced. Again overall sales numbers will support this in my opinion.
AF issues, same complaints as those from years ago, only 1 center AF point and not accurate AF. The later seems to have been addressed with the XF (however as he points out at a cost as the upgrade from the DF or DF+ to XF was not inexpensive), the former, looks like just can't be done. Phase had years to work on this with Mamiya (now they are all one happy family) and after 4 years, they came out with 1 AF point again. They make a big deal about the Honeybee AF system, and I hope that there will be enhancements to it via firmware, but I don't see how they can add more focus points. Looks like it's going to be 1 center point forever, at least as long as you use Phase systems.
