OK I've been a bit of an idiot and marked the focusing screen on my 1Dx. It came back from Canon Service today after getting the sensor cleaned for the issue described in this post; http://www.canonrumors.com/forum/index.php?topic=11331.0
. Sensor a lot cleaner but not perfect, 3 noticeable bodies on it, tried activating the sensor cleaning several times to no avail.
Anyway on taking the camera out of the box I looked through the viewfinder to see a foreign body right in the middle of the viewfinder. How it could leave the Service Centre with that I don't know. So got the blower out to give it a couple of gentle wafts and it slipped and its marked the focusing screen. Does anyone know if there are focusing screens out there that fit the 1Dx? I can see the EC-D fits the 1 Series camera but apart from a place in New Zealand which says that fits the 1Dx I cant see anywhere else that says there is one.
Its not the end of the world, only really noticeable if I'm looking at a plain'ish image that I can see it but if I have to send it off to Canon to get it replaced I would.
Any help appreciated.
