I tried a copy of this lens some weeks ago - with D7000 body. Performance open with F2.8 was wees, soft at 17, 35 and 55mm. With F4.0 ist was very okay... The Autofocus has similar speed as the big 2.8/24-70mm - therefore tried it. The 18-105 is so slow that many shots of kids are not in focus. The DX16-85 has similar slow Autofocus.
Is that normal behaviour of that lens? Should I test different used copies? To bus a used copy is a nice option today...
Thanks, Walter
