I have just changed my D200 for a D7000 with the kit 18-105 lens. However, the quality of the pictures is not comparable with those of my D200: not as sharp, not as much definition and overall a little wooly etc.
I am not the most advanced photographer, so tend to use it in auto setting, though I have tried different shutter speeds and ISO, but still can't get the results. Friends tell me the D7000 should give me even better results than the D200 and advise me the kit lens is not really that good, and that it is probably the lens that is the root of my problems (Wish I had kept all my lenses but sold them with the D200).
I tend to use the camera for fast sports in all conditions and of course the usual family stuff. I would preferably like a lens up to 300mm so was considering the 70-300 but also am worried I will regret not having the lower range. I would appreciate advice and views of suitable lenses.
