If in any camera bag missing 1

This Reinigunspinsel is really worth the money.
At one of the ends is a brush, which is pushed over a small red lever. So it is when it is not needed whatsoever inside the casing and is always well protected during transport. At the other end there is a small round Flies with which applies a cleaning film on the glasses.
To use:

One removes larger particles of dust and fluff you first with the brush end and possibly a blower or by Leicht blow across the surface of the lens or filter. Then there are smudges such as fingerprints pushes you to brush back into the envelope and removed the lid contains the cleaning flow. Now you can use a circular motion to remove these contaminants.

Personal conclusion:

After the first use (especially the cleaning flow) was clear to me this brush I give her no more. I am fully satisfied, because it is not very expensive and you really very effective get any dirt on the glasses. He also has a practical clip to the side so that you can brush sometimes quickly to the shirt or trouser pocket hang without which he lost equal.
