xpan exposure accuracy

[Ian Sabell <ians@xxxxxxxxxx>]

Is anyone else using Hasselblads xpan having problems with under exposure?
I have found that unless I am very carefull not to include any sky in the
frame when
metering and set the exposure compensation dial to +-1 stop then my trans are
all way too dark.+AFs-up to 2 stops out+AF0-
Hasselblad UK. have had the camera back, tested it to an accuracy of 1/50
of a stop, and say it is 'well within normal operating parameters'.
I've also tried using 2 xpans side by side for a comparison and found the
exposures
to be identical.
