Eh, these nanotech dust mites are nuthin' new. Years ago I had a family of
these living in the pentaprism of an OM-1. Every now and again I'd be
looking through the VF and one or two would be wandering across the
screen. Which made it hard to focus if you suffer from arachnophobia like
I do.
But these little buggers are effective, I never had a dirty sensor.
