The Canon EF 2.8L IS USM is now part of one of my favorite lenses. I have previously worked with the EF-S 60mm 2.8L USM, which was also a very sharp lens. The 100mm is worlds better again and the images convince the macro and the Proträtbereich. For me, the lens gets clear 5 Stars. The plastic tube brings me advantages, since the lens with metal body would have even more weight. The image stabilization is needed in the macro range eh not so he is for me not necessary. When taking pictures of Bar is great. The processing, and the optics are very good. Who is on test values may like to look at Taumflieger.de after. There is the lens at the position 9 and therefore one of the sharpest lenses Canon. This lens is for me 100% in the photo backpack. I recommend it to everyone Macro friend.
