Used mainly in macro (I put 2 customer images I realized grasshopper + fly) is a real treat! I will use that with a 1000d canon box, hand freestyle pictures lifted. Map fast, quiet, highly effective stabilizer (this is the important point of my choice) I do not regret my purchase, although I have long hesitated with Canon 100mm. The grip is fast although we must get used to the 3 position away, but it is also part of the stage for a beautiful picture! Tested in portrait or landscape, still great, but I prefer the 50mm 1.8 lighter. In short, a versatile macro lens and making beautiful pictures, it is the goal!
