My D7000 came with the 18-140 mm
Its a pretty good one all around. im also looking for "the next" lense, but as i have the 18.140 stock, i find that it overlaps or ofers almost no diference to other kits...
Youve got lot of lenses, i may say that theres no point to buy anotherone if its going to be f/4
If i where you, i may try to sold all the zooms, and just get a 18-210, or any zoom lens with a fixed F/2 or something similar.
Its more of a "pro lens" as i read about. and Bigger aperture its More Bokeh and more capable of getting better shots at night.
