Title: Raynox DCR 150
Review: I bought this after reading an article in Popular Photography. The article said it was a good, cheap alternative to buying a macro lens. It also showed a sample photo taken with the product, and the quality was quite good. However, the product did not work well with my lens, the Tamron 18-250mm. The vignetting was so severe the image was just a circle in the center of a dark frame. The quality of the image in that circle was not bad, and with certain lenses the product might be worth the money. I would recommend researching what lenses it works well with before buying it. I also think it makes the most sense to use extension tubes for macro work. They don't add any glass in addition to your lens. The only reason I didn't use extension tubes is that they are not made for my camera.
