for the second time since I bought the iq250 back I am having a serios problem -
first the button is pressed but the camera won't take the photo
then even after refreshing - batteries , CF card , re attaching lens and back - the shutter of the 645 DF+ remains up and does not go down.
and then the camera is "paralised"
for the first time I had to send the back to Denmark but they said it had a firmware update ( which I did myself)
now for the second time I am a little out of answers
also there is and icon in the viewfinder that looks like this - -u-
( needless to say the camera works fine with other digital backs and lenses , the problem is in the back )
(almost every photoshoot day comes with its errors and malfunctions ... )
