I got a good set of these when I got my first dslr for xmas 2010. I used them quite a lot with my 18-55 IS kit lens and really enjoyed what I got results wise. I eventually decided I liked macro that much I bought a 100 f2.8 L which was amazing. I didn't need the filters anymore so I sold them off a while back. I've just got an MP-E65 macro lens for this xmas and can't wait to give that a good go. The filters do take a bit of getting used to, but they are very rewarding for the price when you do get it right. You do need plenty of light though as the filter does take light away.
