Cleaning our sensors at home is a fairly straightforward thing to do. I’ve been doing it since I was shooting with a pair of Nikon D100 bodies back in 2002 because sending your camera off to be cleaned was prohibitively expensive back then. These days, most camera stores will offer some kind of cleaning service.
But how do they do it when you send it back to the manufacturer? Specifically, how does Leica do it? This 20-minute video from Leica Society member Hari Subramanyam lets us see the whole process after he took his Leica M (Typ 240) and Leica SL into Leica Camera AG for a sensor clean.
