Should the glass filter depress when pushed?
While I was cleaning this filter (which was mounted on a lens) with a lens pen, I noticed that even a slight push with the pen will cause the glass on the filter to depress downward. If I ease off the pressure on the pen, the glass will come back up. Is this behavior to be expected, or is my filter broken?
It seems like the circular piece of glass is held in place by a ring of rubber, which might explain why it allows for such movement, but the whole thing "feels" so flimsy that I thought I should ask this question.
