I just made a test and C1 4.14 was about 20 seconds (for a 63.7MB P 25 file) and
C1 DB 3.7.8 was about 25 seconds. C1 4 seamed a bit faster.
... then again, Potoshop CS3 did it in about 8 seconds, so there is space for C14 PRO to improve, after all this is only the "light" version of C14. Other programs have cached up with Phase One, but I would not say that they have a software problem. I feel at home with and generally process my work on the field with an old laptop. The tethered connection is extremely reliable and "can do" attitude, I use custom made ICC and the ones that came with Phase like "Easy gray" that works particularly well with installation shots when the white gallery walls have to look white. The profile was made for table top photographers that use a white seamless background.
The only thing missing for my type of work is lens correction and perspective control tools. (something like: edit>transform>skew )
On the down side is the idea that raw conversion instructions on C1 3 are nos compatible with C1 4 which means that you would have to do all the editing work when re-processing images.
If Phase One is consistent the new camera should be:
* Weather resistant and robust (something that the Hy6 and Leaf backs are not)
After all Phase backs can be completely frozen w/out stopping to work.
* Minimalistic interface to make things robust and simple to use. Mamiya has similar tendency.
* Low energy requirements. No fans, no large displays.
* Good, fast, reliable software (something that Mamiya has not)
If you package that with a good support and upgrade policy and competitive pricing they may interest a few photographers.
If I was them I would produce a Phase One ZD model, but that concept -- that failed not because it was a bad idea but because of what Phase One knows how to do well: firmware and the rest -- may be irreparably jinxed like Apple's Newton.
