Phase One 645DF shutter release issue

Postby sledder » Mon Oct 29, 2012 7:37 pm

I have been working with a photographer regularly and for the last month or so, I have been witnessing a really odd reoccurring issue when pressing the shutter release button on the body. He is using the Phase One 645DF with a P40 back

Every so often when shooting, pressing the shutter release does nothing. It simple doesn't respond. Sometimes it may come back to life, other times after a few presses it sounds like the shutter is being released but doesn't capture anything, either on the back or capture one.

I have tried all sorts of things to solve it, I cleaned all the contacts + restarting and removing batteries etc.

I am starting to think that this may be a hardware problem, but thought I would check on here to see if anybody has come across this problem as wel.

Any information would be greatly appreciated.

You do not mention firmware versions for either back or camera. I think regardless, this would be best handled either in a support case or in a dialog with the dealer.

Had this happen with mine where the shutter button doesn't respond then it suddenly fires and I usually get a really over exposed frame.

What seem to have solved it for me was stopping the camera going to sleep so quickly. From memory I think default the camera powers down after 15 seconds which is way too short a time between captures IMO. I have set mine to 60 second and not had the issue since. I think the camera and back get out of sync during power down and need a bit of time to connect together again causing these strange behaviours.
