This kit is nice to use, can be superimposed 2 lenses to increase the approximation, so who can do more can do less, but pay attention to the loss of sharpness). The cover takes up little space and could be accompanied by an old cloth to clean the lenses (the + 10 tends to be in contact with the skin of the hand assembly and disassembly). We must train to manage its position and above all be perfectly still, every millimeter of variation and we fall into the fuzzy, tripod and remote control strongly recommended when conditions permit. In any case, this is an ideal product for a first experience in macro front breaking the bank for a good macro lens. I use it on a 18-105 mm zoom lens and the result is striking. The bokeh swished around the main focus but it gives a little style to the photo.
