How do I attach a filter to my camera? How do I remove a filter from my camera?
To attach a filter to your camera, simply screw it on to the end of the lens, keeping in mind that polarizing filters are intended to spin even when properly attached.
To remove a lens filter, simply unscrew it from the lens by twisting it to the left. If you are removing a polarizing filter, then you will have to ensure you are not turning the outer lip of the filter as that portion rotates freely in order to allow you to set the plane for polarization.
