I have seen my dealer and given him example images. He is sending reports to Phase One. We will see how they answer.
Gotfred sent me some images he made with his back @ISO 800 (Thank You!), I haven't yet fully checked them out.
One unfortunate fact is that once you have noticed the lines your eyes pick them out on every image that has them. I guess if an AD gets one really bad image she might then start to get picky even about the acceptable ones.
Based on some conversations I have had with industry insiders, I am starting to wonder whether this is not a signal processing issue linked to the speed at which the CCD is clocked in the new P+ backs. I don't think it's really a sensor issue. Pure conjecture of course.
The good new in this story is that the current generation of non-microlens sensors with the current electronics in the P+ backs appear to be capable of images processed to at least 1600 ISO if you were happy with the grain of 1600 ISO film and if they fix this striation/banding issue.

These lines shouldn't be there, sure an incorrectly exposed file will have certain noise problems but lines, I dont think so. When you pay 30 grand for something you deserve to have it work correctly. And by the way, I heard from a little birdy in one of the major phase one dealers that strange lines on high iso files with the plus backs is a known issue. I'd demand a refund or a back that didnt have the problem, the non plus backs dont have this issue I heard, mine certainly doesnt, what a great upgrade eh?
