Summary: The mid-priced 18-70mm f/3.5-4.5, is much more than just the ideal compromise. Not many years ago it would have been pure fancy to propose a £200 lens that featured ED glass, an aspherical element, internal focusing and instant manual intervention in AF mode yet that is precisely what Nikon offers...
Pros: Impressive zoom range and consistent image quality
Conclusion: What can we write in summary? We should congratulate users who have such a great lens, while others, for example, Canon users, are still waiting for an equivalent. When we compare the Nikkor 18-70 mm with the Canon 17-85 IS, the advantage goes to the former.
Cons: visible vignetting, especially at the ends of the focal lengths range, high distortion at 18 mm, visible astigmatism
