Well ... provided at the base to protect the lens, I'm a little disappointed because there is a small stain on the glass .... it is not scratched but it looks like a trace of product but do not go away. This does not seem to affect the quality of images but insofar as I am a fussy hair, this is the kind of detail that annoys me. Otherwise, the filter will fit properly on the lens of my HS30 and always turns the lens cap.
