I bought this lens to replace a 18/70 and 70/300 Sigma as traveling or walking one goal is more practical. Performance-wise, with 19 lenses there is necessarily a loss of light and we regret not having an opening 2.8 in certain circumstances. This is a good compromise but no more. The grip is very nice except the manual iris adjustment ring that is often confused with that of zooming Finally for those who like to have a "light" material on the shoulders, you will have to add 850g to your case and this is not anything especially if one has a D300S like me! In conclusion, this is the Nikon and the quality is there.
