The label says 18-200m F/3.5-5.6G Nikkor lens. Focal length and G type are clear. From the lens specs I see that min aperture is F/3.5 and max is F/22. So what does the label aperture range means?

It means that as you zoom the max aperture increases from f3.5 at 18mm to f5.6 at 200mm

  • and in specs f3.5 and f22 are both with 18mm(with minimal focal length)? Is it kind of standard in the specs? – Pablo Dec 17 '11 at 12:43

    Pablo, at 18mm you can set the aperture anywhere between f/3.5 and f/22. At 200mm you can set it between f/5.6 and f/22. If you are at 18mm, and set the aperture to f/3.5, then start zooming the lens to 200mm, you will see the aperture gradually move from 3.5 to 5.6 in your viewfinder. If you start at 18mm and set aperture to f/11, then zoom to 200mm, it will remain fixed at f/11. – MikeW Dec 17 '11 at 19:24
  • @GraemeHutchison - Not true. The minimum aperture has a range too. f/22-f/36 on this particular lens (from 18mm to 200mm respectively) (Reference) – Om Nom Nom Dec 18 '11 at 07:01
