"you gave me some good advice a few weeks back with focus problems on my 5D. i dropped the camera and got 2 contax 645 with 35/45/120/140/210 lenses, i am delighted with my purchase of a P21 digital back."

No need for mockery here,

This is a centerfold error.  the chip sends data off both sides split evenly down the middle, hence the line.  Sometimes there can be a color discrepancy between the sides on some backs.  You just need to get 3.7.8 Beta 1 from Phase and the problem is solved.

Not sure if Leaf has a similar solution yet, had an Aptus 75 with the same problem and it had to go in for recalibration.

yeah i just posted the other, thanks for your answer, that problem is not so frequent as to dampen my enthousiasme for the back, and mainly at 400iso which i try to avoid anyway, in the end i can live with it,could be on shot 1 and noit on the others, i was wondering if it was only my back.
thanks
