Filters come in all shapes and sizes… and qualities. This is a premium product, clear, well made, and a bit thinner than most of the cheap filters out there.
I use them when I am on the motorcycle, and when trekking. Usually I take them off when I shoot, but this filter seems well suited to possibly leaving on if the elements require a bit more protection.
