For example, if you have the kit lens 18-55 mm f/3.5~f/5.6 that means the lens is capable to f/3.5 at the short end i.e. 18mm but in the long end at 55mm only f/5.6 is available.A variable aperture zoom changes the maximum aperture at one-sixth of a stop intervals, for example the 18-55 I mentioned above has these maximum apertures:* 18mm f/3.5* 20mm f/3.8 * 24mm f/4* 26mm f/4.2* 33mm f/4.5* 35mm f/4.8* 39mm f/5* 42mm f/5.3* 48mm and beyond f5.6(focal lengths are approximate, I read them from the lens barrel)The most popular wide aperture lenses new users often buy are AF-S DX 35mm f/1.8G and AF-S 50mm f/1.8G and perhaps AF-S 85mm f/1.8G. Those are prime lenses (single focal length) but they have a pretty big maximum aperture of f/1.8 while at the same time being very affordable. The top-of-the line f/1.4 versions tend to command much higher prices, even several thousand dollars a piece.If you prefer zooms, then Nikkor has for example the AF-S DX 17-55mm f/2.8 constant aperture zoom that opens up to f/2.8 at all zoom settings. It is a very solidly built full metal lens with very good optics, but that unfortunately means a little higher price tag too.</blockquote>
