For the hardcore camera aficionado, owning the thingy with a brush on one end and a bulb on the other is a must. It allows dusting your prized lenses without actually touching the lens itself preventing ugly scratches and smudges unseen with the naked eye.
It may seem clean but an unseen smudge can bend light in a variety of ways leaving you with a totally ruined shot. The brush softly brushes away the dust from the lenses surface while pressing the bulb as you go blows it away. Best to do this each and every time you use the camera so you get crisp and clear shots every time. One more thing, do use the lens cap(the name suggest its proper use) for it saves on a lot of cleaning due to fingerprints and dust.
