As you know, I'm ignorant on the subject. I was looking around after the fact to do some price research on the lens I got, and stumbled across this: http://shop.everfull.com/items/item.aspx?itemid=711604 Is this something that would work well for me? What applications can I use it for? As far as the macro conversion goes, with the zoom of the lens, does that mean I can just get even closer with the macro filter on? Thanks for the help. Seems like a good deal, so I just wanted to check first.
