AF-S DX NIKKOR 16-85mm f/3.5-5.6G ED VR
AF-S DX Zoom-NIKKOR 17-55mm f/2.8G IF-ED
AF-S DX NIKKOR 18-55mm f/3.5-5.6G VR
AF-S DX Zoom-NIKKOR 18-55mm f/3.5-5.6G ED II
AF-S DX Zoom-NIKKOR 18-70mm f/3.5-4.5G IF-ED
AF-S DX NIKKOR 18-105mm f/3.5-5.6G ED VR
AF-S DX NIKKOR 18-200mm f/3.5-5.6G ED VR II
AF-S DX VR Zoom-NIKKOR 18-200mm f/3.5-5.6G IF-ED
AF-S NIKKOR 24-70mm f/2.8G ED
AF Zoom-NIKKOR 24-85mm f/2.8-4D IF
AF-S VR Zoom-NIKKOR 24-120mm f/3.5-5.6G IF-ED
All of the above lenses have a common zoom range of 24-55mm. Lets pick a focal length in that range, 40mm. Do you think that all of the above lenses at that focal length have the same minimum focal distance? I suspect that the minimum focal distance at that focal length (40mm) will determine the maximum magnification (for macro purposes) you will be able to achieve. Do you think they will all be equally sharp at a given magnification and focal length? Do you think the distortion will be equally corrected in all of them in that condition? I suspect that there might be more design trade-offs in say the 18-200mm lens which has a very large zoom range versus say some thing with a more limited zoom range like the 24-70mm (which is more than double the cost of the first zoom).

Sorry for the delay, been a busy couple of days for me. I was meaning that the D50 at work and the D3000 my neighbor have both had lenses that are 18-55mm. Like I said, I really don't know much about cameras. I know how to use the one at work to get really high res pictures of small electronic components, but beyond That I am lost. When I tried to do the same with her D3000, the picture was not quite as good. I assumed it was the same lens since it was 18-55 just like at work. I see you listed 2 different ones so I am assuming that is the difference from what you posted previously.
