Unpopular opinion: stop using canned air on shutter curtains
I keep seeing folks blast dust off their focal plane shutters with canned air. In my experience, that's a fast way to bend a curtain or blow debris deeper into the mechanism. Last month a guy brought in a Nikon F2 where the shutter was dragging, and sure enough, a piece of grit was lodged behind the curtain from exactly this. I use a rubber bulb blower and a soft brush instead, it takes more time but saves you a repair down the line. Has anyone else seen damage from this, or am I being too cautious?
