Nikon blackout (anti reflective) lining in mirror box.

Hi, I have a D750 and have had problems with the Nikon black out anti reflective lining shedding black fibres on to the sensor. At first sight I thought it was hairs or dust from outside and just blew them away. Everybody shooting with a DSLR comes across 'dust' but mine comes from inside the camera. As the sensor resolution increases, anything landing on it for smaller apertures will be visible on the shot. I've posted in this general section because I'm wondering if Nikon have always used the same material in their other DSLRs. I'm short of info because I only have the D750 which has had both Nikon recall mods done. Strictly speaking I would say it is the lining of the mirror box. But if you remove the lens and look into the compartment, does your model have a 'furry' felt like lining, or is it a hard matte black coating?

If you also have a Canon DSLR, do they use the same type of soft felt lining inside their camera mirror boxes?

Feedback appreciated.

All of my bodies have that lining. I haven't had any such problems in 13 years of Nikon DSLR use, so I'm not much help. Good luck.

My old Canon XT had a similar problem. Had to clean off the stuff off almost every time I used it. Problem was it would get in between the focusing screen which wasn't so easy to clean.
That's why I have Nikon gear now. So far no problem's of that kind.
