One of the first things that a friend said about W10 was that he could not load his older pictures.
Images from my now elderly TZ50 load to W7 without a problem, (Until a few days ago, during some copying, Bands starting appearing across the bottom of the recorded image ).
Clive, you will be leased to know that I bought the TZ50 because of the Leitz lens. A superb piece of optics!
(Too tight to spend the extra £90 to get the red dot! )
Maybe I released the shutter release too soon,,before writing was complete, because repeating the exercise, on the same memory card, worked perfectly!
But Clive's experience sounds another knell for W10 to my mind.
