Not bad. I was curious how those cheap filters would work, I ended up getting a set of extension tubes instead which were like $60 and a PITA to deal with so I don't ever end up using them. At least they have contacts so the AF still works, but I am going to have to look into getting a set of these filters now that I know they do something worthwhile. People were trying to get me to buy the Canon filters, like $150 a piece and only one size. I still want that Canon EF 50mm macro lens though.

I love that Duncan. That has to be one of my favorite corals.
