What if a camera lens has a high f number?
The f on a camera lens is the maximum aperture of the lens. It is sometimes listed as 1:X with X being the maximum aperture. For example:- Canon EF 50mm f1.4 is a 50mm prime lens with a maximum aperture of 1.4- Tamron 90mm f2.8 is a 90mm prime lens with a maximum aperture of 2.8- Canon 70-200mm f/4 is a lens with a focal length of 70-200mm and a maximum aperture of 4.
What is apperture?
The main function of a camera lens is to collect light. The aperture of a lens is the diameter of the lens opening and is usually controlled by an iris. The larger the diameter of the aperture, the more light reaches the film / image sensor.Aperture is expressed as F-stop, e.g. F2.8 or f/2.8. The smaller the F-stop number (or f/value), the larger the lens opening (aperture).
What determines the shallowest depth in field in photography?
The largest aperture which is the smallest number on the aperture ring/dial generally anything between f1.2 - f5.6 dependant on the lens and zoom. On most consumer digital cameras the more you zoom in the higher the smallest aperture becomes. eg. Lens at 35mm, widest aperture (shallowest depth of field) generally about f2.8 Zoom in and the largest aperture will reduce to about f5.6
What part of a camera controls the amount of light that enters the camera?
The functional opening is the aperture, the opening that controls the amount of light that hits the photosensitive surface. You may have a camera with interchangeable lenses that screw into and out of the camera's body. The opening into which the lens is screwed is not the aperture.

Why aperture start from 2.8?
In general, aperture does not start at 2.8. The aperture of a particular lens, however, can start at 2.8 depending on how the lens was built. Some lenses are designed so that the lowest f stop (aperture) is 2.8. Some lenses aperturef-stop may start at 1.4. Or 5.6. It just depends on the lens. So....again, in general, aperture does NOT start at 2.8.

What does the aperture dial do on a camera?
The aperture ring changes the lens aperture which controls how much light reaches the film or digital sensor. A large aperture f/1.4 to f/2.8 = lots of light, fast shutter speeds, narrow depth of field A small aperture f/9+ = much less light, slower shutter speeds, wide depth of field
Aperture?
Opening of the lens diaphragm through which light passes
