I figured it was time to showcase an invaluable little tool I carry around it my kit. This is the top of my useful Lenspen.
This little device has saved me from a bad picture due to dirty glass. It clears away smudges, dirt, and anything else that may have made it's way onto my lenses in the course of a shoot. It's the most useful thing for cleaning my lenses - and I've tried most things on the market.
Hold tight another update is on its way.
