I've had this little gem in my Amazon wish list for about 5 months now. I would LOVE to have a macro lens for my camera, but those are a little out of my price range right now. Instead I thought I would try out some macro lens sets. I really couldn't go wrong. I saved up my Swagbuck's to cash in for Amazon gift cards and ended up only paying less than $5 out of pocket.
They came in a nice little case and fit my D40 perfectly, no adapter needed. For the price I'm quite happy with these. They take some getting used to, because they work like a magnifying glass really. You kind of have to play around with the focus some and I found that it was a bit easier to shoot in manual focus (although the bright sunlight was a bit blinding so some were not quite in focus). If you're looking into buying some lens filters, I would just recommend checking your lens diameter first. All mine were 52 mm so these fit all of them!
Anyway, I had fun playing around with my new toy when it conveniently came in the mail just a few days before we left for vacation. I have some knitting books and a recipe book in my wish list that I've been saving up for, but I went with these for now. I thought they would be fun to have on our trip!
