I've never written an Amazon review, but I've never been so excited about a product. I had this lens tentatively ordered to take some pictures at a birthday party without flash can, what should thanks to f / 1.8 be possible. In fact, I was not disappointed. But that's not all: in other recordings in daylight and in lit rooms me the images have really blown away. So a color brilliance and beautiful depth of field, I have not kept in a lens for ~ 100 euros for possible. This lens opens up completely new possibilities for me creatively to photograph and is from well be now at any time, for I would not have missed this gem not more. The problems with the autofocus of which reported partial could I find not so far. Of course, it does not focus so quiet like a USM and is not adjustable in the AF mode, but that does not bother me .... and even not at all for this price. Small and light, the good part is even. For you!
