I took Nikon 18-105mm f / 3.5-5.6 focuses quickly and clearly, When buying, be sure to do a back / front test, I bought only the third copy, So take it, you won't regret it.
With its pros:
Sharp enough for a zoom, lightweight, compact, well-built, quiet autofocus, excellent stub, inexpensive.
With its cons:
In low light conditions it takes a long time to focus.
