I just bought LensPen Propack today (it's now $18 already), and it has 4 pens inside, 3 of which are of different sizes and used for lenses of different camera types. I just wonder why do they have to produce 3 different types, each for a particular lens? Would anything happen if I use the wrong one?
Btw, I leave the 4th one (digiKlear) since it is used to clean display screen and i assume that the product may differ from the others. Am I right on this?
