I bought this filter to use with the Canon Powershot G1X. Since this camera offers no protection through a lens closure, but only a cap, the filter seems a truly obvious need. Without the filter, the cap must be removed and replaced for continuous protection while shooting casually. With the filter, you simply leave it in place after installing and shoot as you wish. This is what pro shooters do to protect their investment in expensive lenses; the 58mm filter offers the same protection for smaller cameras with mounting capabilities or accessories.
Bottom Line Yes, I would recommend this to a friend
