I have in addition to my camera kit D5100 Nikkor 18-55 for macro shooting the 40mm Micro 1: 2.8 for just under 250, - increased and must say that I am absolutely delighted with the image quality and sharpness of the images. When compared to the acceptable kit lens that is better 40mm in my opinion two classes. Thanks to sufficient resolution can be for normal users and more distant objects yet passable larger (by clipping). Impressive is the sharpness of the images and the color brilliance. I have not seen anything better in this price league. Only the old 60mm possibly is still a touch better - but also three times as expensive. The only shortcoming is the very light version, which suggests not too much long-term durability. But as I leave the lens on it with very few exceptions to my 5100, I hope that keeps everything for a while. For the price there must be a total of 5 star but then, as a devaluation of the lightweight construction of the outstanding qualities in the illumination are more than compensated. if it eventually breaks down I'll buy again one.
