f/2.8 is common for high-end zooms and f/3.5 to f/5.6 for cheap ones. Aperture is defined as the opening in a lens the. (Note that the maximum "wide open" aperture will vary based on each lens design. Aperture should be referred to as smaller or larger, not lower and higher. That's a bit confusing, so really it's better to avoid "small" and "large" (or "high" and "low") altogether and talk about "fast" and "slow". This means that a "smaller f-number" where the number is low is a larger aperture, not a smaller one. A wider aperture however also means a narrower depth of field. That in turn means that you can freeze action, reduce camera shake and get less noisy images. This allows you to use a faster shutter speed or a lower ISO. By: Search Advanced search Search titles.

Unless there's further context about physical size, "small aperture" almost always means a higher f-number. Aperture is the opening of the lens through which light passes.
