Since I was looking for an improvement to the 18-55 kit lens for my D40x and did not want to spend over 1000euro a 2.8er professional lens, I spontaneously this part for relatively little money, so to speak taken in the local art market to test times. Here are my impressions: visibly better image quality (sharper, better contrast) very good image stabilization, manual Fokossierung possible in Auto mode, the weight is higher, it is thicker and slightly longer than the 18-55 kit lens, the rotation zoom is better to use, total solidly constructed and very inexpensive! Suitable for everyone who are looking for an improvement to the series optics, but do not want to spend much endless, hence my recommendation - 5 stars! ! ! ! !
