| (Slim) MC Lens Protector on screwed on top of my 18-55mm Lens |
The lens filter / protector... does it have a purpose? I have read up quite a bit the last couple of weeks to re-educate myself in order to make a determination if I should invest in it, or not...
Wiki describes it as follows:
"In photography and videography, a filter is a camera accessory consisting of an optical filter that can be inserted in the optical path. The filter can be a square or oblong shape mounted in a holder accessory, or, more commonly, a glass or plastic disk with a metal or plastic ring frame, which can be screwed in front of or clipped onto the lens."
