I opted for this lens because I came to the taste of the Macro-Photography thanks to my "Canon 28-135mm IS USM" even if this was only partly feasible in the 28-135mm and I also have a good lens for portraits was looking for. Thanks to the consistently very positive reviews and the help of some hobbies, but also more professional photographer I am quite fast for this objective decided and am after 3 weeks of testing on my Canon 5D MK II more than satisfied, very fine workmanship, great image quality, madness sharpness , great bokeh, especially for portrait and macro shots exactly what I was looking for, and this objective can I only recommend highly!
