Many thanks for the replies. Ray, I'm that guy too, putting the camera in the pockets & bag with everything else which hasn't been a problem with my mirrorless system, as any dust is swiftly moved by direct access to the sensor. Of course, no one expects any camera to be immune from dust, but it does seem that this is an issue that has been raised by GR owners whilst prior to this thread, there was not one concern or issue on the same subject that I could find from any Coolpix A users. I'm actually raising this query as part of my considerations for the new version of the Coolpix A which *should* be coming out later this year. Yes, I know that just because it may not be an issue with the current version that it won't crop up on the next version but still, every bit of info however seemingly small, helps. Thanks again.
