Never had any Gaffer Tape. Maybe I should pick some up for my camera bag.
I recently bought a new (old stock I suppose now) Ricoh GR ll and carry it about in my small Vanguard (attaches to trouser belt) camera bag. I wanted to get an Air Dust Blower / Soft Brush to clean the lens of dust to fit into the camera bag. I was surprised how difficult it was to get. No one seem to carry it in their store anymore, but I was able to order one online.
Maybe a sign of the times and a sign that I'm an old geezer
...who considers one of these little blower brushes as an essential piece of camera kit.
I've been using these little brushes since the late '60's and I was surprised how rare...in local stores anyway.... they seem to be. At one time they were staple stock.
