Used my led torch shone at and check my lens, noticed specks of dust that i can't clean it off no matter what. or blow with a blower. They just keep appear and appear.
is this normal?
And how do you guys clean the "most fragile and expensive piece of" all photog equipment?
I have been using a 3M Microfiber Lens Cleaning Cloth to just wipe the surface then use a blower to blow off the dust.
Anything more i should do or must get to properly keep my lenses clean and proper?
