My X-T2 had a battery die while shooting. It lead to a couple of corrupt files on the card and the Camera reverting back to Japanese language settings. I managed to reset the settings back to English but now I have 'ND' in the top left corner of the viewfinder/screen (attached image). it shows the ND both with and without the lens attached.
I have searched the internet and the X-T2 Handbook, posts seem to infer its a built in 'Neutral Density' filter? but I cannot find anywhere this can be turned on or off in the X-T2 Firmware is V4.40 - The Shutter speed is blank in the image because no light is getting into the lens.
Many Thanks
Paul...
