Thanks Donald for answering my questions. Thanks everyone for the input..I appreciate it :-)....so even though I assumed the quantary filters would be good enough I may be better off w/ the slightly more costly hoya...It's not like I have the most elaborate lenses to begin w/...but now I am in a delima. I am thinking of returning some merchandise ;-) I hate doing that...oh well. The quantary filters were nearly as much as the popular hoya...so I am wondering. I wish I was some sort of expert w/a lab. Then I would know for sure. -jeff :-)
