Dear community, sorry for writing in english, but my german vocabulary is not enough.
My problem is that the viewfinder has a mask and I cannot take it out.
With or without light is impossible to distinguish if the object is in focus or not, only after the image is taken I can see in the display.
Attached are two pictures from a Nikon D750 bought 1 month ago. They were taken with a mobile throw the viewfinfer.
I went to the store to compare with another camera, and there the viewfinder is without any mask, the 3 sales guys had not idea how to remove it. Their advise was to send it to a special technical in Munich.
I've tried a lot of things to remove this blurry mask, from erasing all the settings (two green dots), change a lot of options, searched in internet, until now, adsolutly nothing...
The firmware is the last, I've checked in the Nikon website.
Can anyone please help me.
Vielen Dank.
