This too happened to me yesterday on a, for me, important photosession - luckily I had my truthfull workhorse Canon 1Ds2 with me - saved my butt.
I adress this to Hasselblad :
This camera, H3D2-39, which has just passed 4.000 exposures comes out with a calibration error.... .... you can´t be serious ??? I have had this camera for less than 1 year, bought directly from a Hasselblad representative, and not sure if I have a warranty on this purchase...
If not, I´m going Phase One or Leaf directly and don´t look back. Really like the feel the Hasselblad lenses provide, but this camera - I just don´t trust it. Have been with me on 3 weddings, and everytime i had to rely on my Canon.
I have been using Hasselblad for over 20 years, but for the first time, I don´t trust Hasselblad.
Tell me what to do Hasselblad
Pictures where taken on 50 Iso, with a 100mm/2.2@F8 and with a sync cable connected to Elinchrome RX1200 system - and after just 20 pictures, my exposures started show up in display correct for 2 seconds, and then goes into black, with 2 purple stripes and later it turned black and with a green random area. After this, all the other pictures on card where destroyed too.
I cannot firmware upgrade from Phocus 2.5 - the menu for upgrade is greyed out.
Tried remove the prism, battery and lens - still no function to upgrade.
If i have to throw any kind of money after this - in case of repair, you just lost a Hasselblad user for good. So much money spend on .... what.... a camera you cannot trust.
