So we spent a week up north hanging out on gorgeous beaches etc, and what happens? One of my lenses gets sand in it.
I'm pretty good at caring for my lenses and gear, so was quite surprised to find 1 or 2 grains of sand under the focus ring (not inside the glass etc). Manually focusing does make a grinding noise, but auto focussing doesn't.
It's not a big deal to me, the lens still works perfectly, but how can I get these grains out from under the ring?
