I've had this lens for a few weeks and it is the best macro I have ever used. I have the Tokina a-tx 90mm f2.5, the Lester Dine 105mm f2.8, and I've used many other macros. This lens has the best color and IQ I have seen. I am a macro junky and I am addicted to this lens now. Just sorry I waited so long to get one. Here are some examples from a recent field trip.
