"In summary, as you can clearly see from this review, the Nikon 18-300mm is a very average lens with average performance overall. It is optically worse than the 18-200mm and it is much bigger and heavier in comparison. It has plenty of distortion, chromatic aberration, vignetting and other issues, but worst of all – its optical performance and focus accuracy at long focal lengths is disappointing. Personally, I would rather opt for the 18-105mm kit lens or the 18-200mm, both of which are cheaper and better optically. Add the focus breathing “feature” and it becomes more like a 18-135mm lens, so you are not getting the full 300mm anyway (except if shooting objects at infinity)."
