Nikon 24-70 on my D4, Nikon 70-200 on my D800, Nikon 28-300 on my D610, Nikon 18-200 on my D7000, Sigma 18-35 on my D7100 and Nikon 50 on my D2X. On my Sony A900 Sony Zeiss 24-70, A850 G70-300 and on my A77 Zeiss 18-300.
Surely you don't walk around with all that hardware!
On my D5100 I use de 18-200mm Zoom as my walk-around lens and th 35mm for street photography. On the D600 I use the 24-120 mm zoom. For macro photography I prefer the 105mm MicroNIKKOR ... sharper lens was never made. Best of luck and happy shooting !
