you do not know that too? Dust settles after repeated use on the lens down and you try desperately to wipe away, in the worst case, you still behind fingerprints on the lens. That's why I've let these bellows of Hama come into the house and am sher satisfied. Unpack and get started, it MUST not be plugged together or otherwise.
It blows the dust directly from the lens and that really works, I'm thrilled and highly recommend this little helper CONTINUE.
Bravo! : D
