Since a few days there are videos showing a "problem" with the D750.
I read some other people have taken some D750 cameras back for issues with light on the top right, tried some D750 cameras and found some without the issue. It seems an exaggeration to me, people want to find issues with the latest (cameras) to show off they found it and thus deserve attention. (which I'm sadly giving here) Anybody here that believes there is an issue, somebody who experienced it?
