I'll echo the ideas in Howard's post. My midrange kit for film was a 35-70mm f/2.8 AF. I added a 24mm f/2.8 AFD for travel and an 85mm f/1.8 AF for kits/school. The lenses were added over time and kept me from having to make the whole expenditure all at once. I eventually added a 24-85mm f/3.5-4.5G AFS lens for travel and that became a workhorse much like the 18-70mm f/3.5-4.5 AFS DX lens is/was for folks with DX format cameras.
I still have all those lenses and they are hard at work on DX and FF cameras. The 35-70mm f/2.8 AFD lens has been compared on Nikonians to the venerable but much larger 28-70mm f/2.8 AFS lens. Optically it holds it's own very nicely. The 35-70 was my only lens for quite a while.
My kit over time has grown to include (for available light photography), 24mm f/2.8 AFD, 35mm f/2 AFD, 50mm f/1.4 AFD, 105mm f/2.5 AIS and 28mm f/2 AIS... the latter two are manual focus but some of the best optics for their purpose every to come in a Nikon label.
Roger It is still ISO, aperture and shutter speed, right?
