Make sure that you are aware of the way this lens operates.  It is almost like using a microscope.  I have included the two photos I took with this lens so you can get an idea of what it is capable of.  The focus ring on the lens is used to adjust magnification from life size to five times life size.  You can literally fill the frame with a grain of rice.  Focus is achieved by moving the camera or moving the subject.  A tripod is a must and good lighting is also very helpful with depth of field.
