I am in need of a 52mm and a 72mm UV and am wondering about quality. There are such varying degrees of price, that I'm not certain what I need to spend. :?: I see $15 filters, but are they any good? Can someone offer a bit of input on this one? I've normally spent very little on filters, but since my equipment and glass is by far much more expensive than ever, I am left wondering. Thanks for any help!! Jon The lense I'm fitting are the 24-120VR and the 50mm.
