Last week when granddaughter visited she found a small, round container with a twisting lid that fascinated her. She practiced and practiced and practiced twisting that lid off. I didn't give it a second thought until she visited today and I learned that she can now twist all the rear lens covers off my lenses. How quickly they learn!
@leonbuys83 You are very observant. She did pick a couple of lenses and when I realized she was taking off the rear lens covers I took them away and let her hold the extension tubes for moment or two. She was easily diverted to blowing bubbles shortly after.
@vignouse that sounds like my father speaking, who was paranoid about children and stickiness, particularly his grandchild
