At some point did Nikon change the material that is used for the monitor screen? On any of my previous Nikon digitals, the monitor screen is constantly in need of cleaning, e.g. D40, D3300, D5600. When I bought a Z50 I didn’t think it would be any different. To my surprise and satisfaction, the Z50 screen seems MUCH more resistant to finger marks etc. The glass must be made of different material a definite improvement, a schmutz free view!
