Well I am trying my brother's camera a beautifull H4D40 with very low actuations. I encounter this recurrent problem : when I wake up the camera after few seconds of inactivity , the lens shutter close ; I have to press mirror up button two times to cock the shutter again. Very strange behaviour, isn't it ? This happens with the Hcd 100 and the Hcd 28 too.
Annoter strange thing : the autofocus motor won't work on the Hcd 35-90. I havé cleaned all the electrical contacts, but nada .
Have you ever heard about such behaviour on the H4D40 ? I havé to tell that the camera has never been upgraded since hé bought it.
