Hi Frog and Charles.
Thanks for your advise Frog.
Have decided to study my D40x for now and see what I can learn.
Currently I have the AF-S 18-55mm,1.35-5.6 GII ED and AF-S 55-200, 1:4-5.6 ED VR lenses,
and would appreciate what you gents would consider a great lens upgrade for either on.
Assume for this exercise that money is no object
