After hearing all the praise for Sigma's Art line of lenses I decided to purchase the 35mm and I could not be more happy with my purchase. It is sharp wide open and the bokeh is beautiful. I'll be adding other prime lenses from their art line to my camera bag.
These lenses are clip-on style, which is preferable to the stick-on type. They are not professional quality lenses, but for the price they are acceptable. My wife wanted a macro, and that one works well. The fisheye would not focus on her phone, but worked okay on my daughter's phone. These are nice little lenses for occasional use. If you're looking for exceptional quality, use a good camera with proper lenses.
