This is one of the better quality lens's I've seen.  I love how close you can get to things.  The only thing I wish it had were more than just this lens like a wide that were wide angle or super far away one.  

I work for  Gifts From Poseidon. Doing online and at even oysters openings for pearl jewelry. I now use this to show the pearls off. It lets me get up close without losing image quality or having to use multiple expensive pieces of equipment to take a photo or do a quick live video. As I can easily put this on my phone to show the pearl and than take it off
