RX 10 III Viewfinder cropped when zoomed out

[glecatte]

Not sure this is the correct board. 

We've just gone on holiday with our Rx10 iii, when you view the live picture (either viewfinder) when zoomed out the top right and bottom left have a blurred black crop.

It disappears when zoomed in a little. 

Any ideas / suggestions?

Hey glecatte, that's odd! Does it affect the picture taken?

Also, try the basics: https://helpguide.sony.net/dsc/1610/v1/en/contents/TP0000808749.html
