I have been perplexed by the range of prices for UV filters so thought I'd try a couple of these. I figured that at this price if they turned out to be unsuitable I wouldn't have paid out lots of money. They came nicely packaged in plastic foam lined containers and easily fitted my lens. They certainly seem substantial and clear. They have the dual thread so I have easily been able to attach other filters, without having to first remove these filters from the lens. Even if you decide to upgrade to more expensive filters at a later date, these appear to more than serve their purpose, allowing you to put the money you save towards more pricey camera equipment!
