|This handy little lens pen from Hama is a must – it easily shifts dust and greasy marks from your lens and other glass surfaces, like your LCD screen or viewfinder. One end of the pen is a soft retractable brush for getting rid of small loose particles, whilst the other end is a special velvet-like pad. It’s the special carbon-based compound though which is the true hero. This dry cleaning agent is contained within the cap and the pad is replenished with this compound when the cap is on, ready for use the next time. Rub the pad gently over greasy marks and fingerprints and watch them disappear.
